What is an easy out tool? An easy out tool, often called a screw extractor, is a specialized device used to remove screws, bolts, or studs that have broken off flush with a surface or have heads that are too damaged to grip. Can I use an easy out on any broken fastener? Generally, yes, but the success often depends on the material and how tightly the fastener is seized.
This guide will give you clear, step-by-step stripped screw remover directions to successfully complete damaged screw extraction. We will focus on easy out tool usage for common workshop and home repairs, detailing the entire process from preparation to final removal.
Deciphering the Anatomy of an Easy Out Tool
Before diving into the steps, it helps to know what your tools are. A standard screw extractor kit instructions usually include a set of extractors and often a matching drill bit set.
Components of a Screw Extractor Set
- Reverse Drill Bits (Left-Handed Bits): These drill bits spin counter-clockwise. Sometimes, drilling with these alone can loosen the fastener.
- Tapered Screw Extractor (The ‘Easy Out’): This tool has sharp, left-hand spiral threads. These threads bite into the metal as you turn them counter-clockwise, allowing you to twist the fastener out.
- Extractor Handle/Taps Wrench: Used to hold and turn the extractor by hand.
Table 1: Tool Comparison for Fastener Removal
| Tool Name | Primary Function | Best Used When… | Key Feature |
|---|---|---|---|
| Standard Drill Bit | Creating a pilot hole | Head is intact or accessible | Spins clockwise (usually) |
| Reverse Drill Bit | Creating a pilot hole and potentially removing the fastener | Fastener is lightly seized | Spins counter-clockwise |
| Easy Out Tool | Gripping and twisting out the fastener | Head is sheared off or completely stripped | Left-hand spiral threads |
| Using a Bolt Extractor | Removing large, seized bolts | Bolt head is rounded off severely | External gripping teeth |
Preparation: Setting the Stage for Success
Proper prep work makes the whole process easier. Rushing here often leads to a broken tool inside the broken fastener—a much bigger problem. This part covers the initial steps for broken screw removal guide.
Safety First
Always protect yourself. Wear safety glasses. You will be drilling metal, and shards can fly off.
Cleaning the Area
Use a wire brush to clean around the broken fastener. Remove rust, dirt, or paint. A clean surface helps your drill bit stay centered.
Marking the Center Point
This step is crucial for accuracy. If you drill off-center, you risk widening the hole too much or hitting the surrounding material.
- Center Punch: Use a center punch and a hammer to make a small dent exactly in the middle of the broken piece. This dent guides your drill bit perfectly.
- Lubrication: Apply cutting oil or penetrating oil to the area. Let it soak for 15 minutes. This reduces heat and friction during drilling.
Step-by-Step Guide: Extracting the Fastener
This section details the core process for easy out tool usage, covering drilling and extraction. If you are extracting a broken bolt, these steps apply, though larger bolts might require more power tools.
Step 1: Selecting the Right Drill Bit Size
The size of your drill bit depends on the size of the fastener you are trying to remove. You must drill a hole deep enough for the extractor to grip, but not so large that you destroy the threads of the surrounding material.
- Rule of Thumb: Use a drill bit slightly smaller than the diameter of the screw’s shank (the unthreaded part).
- Consulting Charts: Many screw extractor kit instructions include a chart showing which drill bit corresponds to which extractor size. Always check your specific kit’s guide.
Step 2: Drilling the Pilot Hole
This is often the most challenging part of damaged screw extraction.
Using Standard Drill Bits
- Start Slow: Begin drilling very slowly. High speed generates excessive heat, which can harden the surrounding metal, making extraction harder.
- Use Proper Speed: Use a slow to medium speed setting on your drill. Keep the drill perfectly perpendicular (straight up and down) to the surface.
- Maintain Pressure: Apply steady, firm pressure. If the screw is steel, you may need a cobalt bit for durability.
Considering Reverse Drill Bits
If you are using a bolt extractor or a screw extractor, many professionals suggest trying a reverse drill bit first.
- The Benefit: As the reverse bit spins counter-clockwise, the friction and torque might actually cause the broken screw to back itself out before you even need the actual extractor.
- Procedure: Drill slowly with the reverse bit. If the screw starts turning, stop immediately and let the drill remove it. If it doesn’t move, proceed to Step 3.
Step 3: Preparing for the Extractor
If the pilot hole is complete, clear out any metal shavings before inserting the extractor. Use compressed air or a small pick.
Step 4: Inserting the Easy Out Tool
This is where the tapered screw extractor method comes into play.
- Choose the Right Extractor: Select the extractor that fits snugly into your newly drilled pilot hole.
- Insert: Place the tapered end of the extractor into the hole.
- Engage: Attach your tap wrench or T-handle to the end of the extractor. You want to turn this counter-clockwise.
Step 5: The Extraction Process
This requires patience and consistent force.
- Apply Turning Force: Begin turning the extractor slowly counter-clockwise. You should feel the extractor bite into the metal of the pilot hole wall.
- Listen and Feel: As the threads of the extractor wedge deeper, they exert rotational force on the broken screw. If you feel significant resistance, stop. Forcing it too hard risks snapping the extractor inside the hole, which is extremely difficult to drill out.
- If Stuck (Heat and Penetrating Oil): If the screw won’t budge, apply more penetrating oil and gently heat the surrounding material with a small propane torch (if the material allows for heat—avoid heat on plastics or near flammable materials). The heat causes the surrounding material to expand slightly, loosening its grip on the screw threads. Let it cool slightly, then try turning the extractor again.
Step 6: Successful Removal
Once the extractor bites firmly, continue turning slowly and steadily counter-clockwise. The broken screw should start backing out. Once it is loose enough, you can usually finish removing it by hand or with pliers.
Advanced Techniques: When the Easy Out Fails
Sometimes, even following the screw extractor kit instructions perfectly, the fastener remains stuck, or worse, the extractor breaks. This section covers handling these difficult scenarios.
Dealing with a Snapped Extractor
If the hardened steel of the extractor snaps inside the hole, you face a major challenge because extractors are harder than most drill bits.
Option 1: Using a Tap and Die Set for Removal
If the extractor breaks flush or slightly recessed, you might be able to use a tap and die set for removal.
- Drill Out the Extractor (Carefully): You need a specialized carbide or diamond-tipped drill bit, as standard bits will not cut the hardened extractor steel. Drill a hole inside the broken extractor piece, slowly widening it.
- Using the Tap: Once you have drilled a pilot hole inside the broken extractor, you can use a slightly undersized tap (which cuts internal threads) to try and break up the remaining extractor material or create new threads that might help pull it loose. This is advanced work.
Option 2: EDM or Grinding
For professional shops, Electrical Discharge Machining (EDM) can vaporize the broken extractor. For DIYers, careful grinding or Dremel work to chip away the remaining metal might be the only physical option if you cannot drill it.
Alternative Extraction Methods
If you are extracting a broken bolt or screw and the easy out method seems too risky for the material:
1. Welding a Nut
For larger, broken bolts, a common technique is welding a new nut onto the stub of the broken bolt. The heat from the welding process helps break the rust bond, and the new nut gives you a large, strong surface to grip with a wrench. This requires welding equipment.
2. Using a Bolt Extractor (External Grip)
If the bolt head is just rounded off (not sheared), a dedicated using a bolt extractor tool is often better than an easy out. These tools grip the outside diameter of the rounded head, providing excellent leverage.
3. Creating a New Slot
If the break is accessible and you have a rotary tool (like a Dremel):
- Cut a straight, deep slot across the top of the broken fastener.
- Use a large, flat-head screwdriver or a chisel to try and turn the screw out. This is similar to how you would use a stripped screw remover directions method for a standard stripped head.
Maintaining Your Tools
Proper care extends the life of your screw extractor set. Extractors are hardened steel and can be brittle if dropped or subjected to side loads.
- Cleaning: Always clean oil and metal dust from the threads after use.
- Storage: Store them in their original case. Avoid letting them bang around with other metal tools, which can chip the fine threads.
- Heat Management: When drilling, use lubrication religiously. Excessive heat dulls bits and can weaken the extractor itself, leading to breakage during the critical turning phase.
Comprehending Torque and Resistance
When you use an easy out, you are applying torque (turning force). The key to success is applying enough torque to overcome the friction holding the screw in place, but not so much that you exceed the shear strength of the extractor itself.
Factors Influencing Resistance
- Corrosion/Rust: Rust acts like glue, bonding the screw threads to the material. Heat and penetrating oil are essential here.
- Material Hardness: Hard steel screws are harder to drill and grip. Softer screws might be easier to drill but can cause the extractor threads to strip if you turn too fast.
- Depth of Break: If the break is deep below the surface, the pressure needed to engage the extractor is much higher.
Comparing Extraction Methods by Difficulty
| Scenario | Recommended Initial Method | Difficulty Level |
|---|---|---|
| Screw head slightly stripped | Wax or friction grip compound | Easy |
| Screw head completely rounded | External Bolt Extractor | Medium |
| Screw head sheared off, accessible | Easy Out Tool (Tapered Screw Extractor Method) | Medium to Hard |
| Screw head sheared off, deep recess | Easy Out Tool followed by heat treatment | Hard |
| Extractor breaks inside the hole | Carbide drilling or professional EDM | Very Hard |
FAQ About Easy Out Tools
Q: Can I reuse an easy out tool after it breaks a screw?
A: If the easy out breaks cleanly and is not damaged itself, you might reuse it. However, if it breaks inside the fastener, it is usually ruined for that specific hole, and the broken piece must be dealt with first.
Q: Should I use a hammer on the easy out tool?
A: Yes, often you should gently tap the end of the extractor (while it is in the hole) a few times with a hammer before turning. This jarring action can help set the sharp threads deeper into the metal, improving the grip necessary for extracting a broken bolt.
Q: What is the difference between an easy out and a screw extractor?
A: These terms are often used interchangeably. “Easy Out” is a common brand name that has become generic for the spiral-fluted tool. A screw extractor kit instructions typically contains these spiral-fluted tools.
Q: Can I use a Dremel tool instead of drilling?
A: A Dremel can be useful for cutting a slot into a stripped head (see Advanced Techniques), but it cannot create the precise, deep pilot hole necessary for a standard easy out.
Q: Is it better to drill slowly or quickly?
A: Always drill slowly. Fast drilling generates immense heat. This heat can temper (harden) the broken fastener, making it nearly impossible to drill through later, and it increases the risk of snapping your drill bit or the extractor. Slow speed maximizes control.
