Stripped fasteners aren’t just a technician’s annoyance—they’re a symptom of deeper process issues that can lead to production delays, scrapped parts, and even safety hazards. Whether you’re building aircraft components, servicing heavy vehicles, or assembling sensitive electronics, stripped threads usually mean torque wasn’t applied properly.
Thankfully, a variety of precision-engineered torque tools exist to make stripped fasteners a thing of the past. In this article, we’ll cover the most effective tool types for prevention and explain why they work.
Why Fastener Stripping Happens
Stripping occurs when torque applied to a fastener exceeds the tensile or shear strength of the threads—damaging either the bolt, nut, or mating material. Common causes include:
- ❌ Over-tightening due to operator error
- ❌ Worn-out or miscalibrated tools
- ❌ Poor tool selection for delicate or soft materials
- ❌ Lack of torque verification before shift start
In high-volume assembly environments, even a handful of stripped fasteners per shift can result in rework, failed quality audits, or costly warranty claims.
✅ The Right Tools Prevent Stripped Threads
The best torque tools prevent over-torqueing before it becomes a problem. These tools are designed with built-in mechanisms that:
- Enforce strict torque limits
- Prevent operator over-rotation
- Deliver consistent, repeatable results regardless of technique
Let’s break down the top options.
Cam-over tools are engineered to slip or disengage once the preset torque is reached—physically preventing the user from applying additional torque. These are among the safest tools for avoiding stripped threads.
Why It Works:
- Torque-limiting clutch slips automatically
- Operator technique doesn’t affect torque output
- Preset torque value factory-calibrated for accuracy
Best For:
- Electronics and PCB assembly
- Medical device manufacturing
- Aerospace components with fragile fittings
Need flexibility? FGA screwdrivers combine cam-over safety with a user-adjustable torque scale—making them ideal for facilities working with multiple fastener sizes and torque specs.
Why It Works:
- Slip mechanism still protects threads
- Torque range adjustable with external scale
- More versatile than preset models
Best For:
- Repair shops and R&D labs
- Multi-line production environments
- Technicians who rotate between assemblies
Sturtevant Richmont Preset Click Wrenches (LTC, SLTC-FM)
When working with larger bolts or industrial materials, click-style torque wrenches offer a tactile and audible cue when the preset torque value is reached—ensuring controlled tightening without guesswork.
Why It Works:
- Factory-preset torque values
- Heavy-duty design for daily use
- Built-in click limits reduce over-tightening
Best For:
- Aircraft structural panels
- Automotive drivetrain assemblies
- Industrial pipe fittings and bracketing

Torque Testers & Verification Systems
A tool that was accurate six months ago may no longer be within tolerance. Verifying your torque tools daily—especially before mission-critical shifts—helps identify drift and avoids problems before they reach the assembly.
Recommended Products:
- Mountz EZ-TorQ III Analyzer: A portable, audit-friendly tester used for click and cam-over screwdrivers
- Mountz Rotary & Inline Torque Sensors: Ideal for production tool validation and real-time data feedback
Why It Works:
- Confirms accuracy before use
- Prevents “unknown” over-torque events
- Keeps QA and compliance logs up-to-date
Pro Tips to Avoid Stripped Fasteners
Even the best tool fails if used incorrectly. Pair good gear with good habits:
- ✅ Never use torque tools to loosen fasteners
- ✅ Don’t apply extra turns after a “click” or “slip” cue
- ✅ Recalibrate torque tools regularly
- ✅ Store tools in clean, protective cases

Real-World Application
In a medical device assembly line, engineers at one facility found frequent thread failures in their aluminum enclosure screws. After switching from basic manual screwdrivers to Mountz cam-over torque tools preset at 10 in-lbs, failure rates dropped by 95%.
Similarly, in an automotive HVAC production cell, switching to preset click wrenches with slip detection eliminated overtightening in high-volume bolt applications—improving inspection pass rates and reducing operator strain.
Prevent Damage with the Right Torque Tools
Stripped threads aren’t inevitable—they’re preventable. With smart torque control strategies and tool choices like cam-over drivers, click wrenches, and regular verification equipment, your team can work faster, safer, and with fewer costly mistakes.
