5-Piece Torque Limiting Extension Bar Set

Brief Overview

This five-bar torque limiting extension set is engineered to protect fastener integrity by preventing over-tightening on critical bolts and nuts. Using proven torsion bar technology, each extension bar is calibrated to slip at a specific torque threshold—a practical safeguard that reduces warranty returns and on-site comebacks. The color-coded design accelerates identification under time pressure, while the comprehensive torque range (75–150 ft-lbs / 100–150 NM) covers most passenger car and light commercial vehicle applications. For shops looking to standardize torque discipline across teams, this set works alongside standard 3/8-inch extension bars to build a complete fastening solution.

Key Features

• Five Calibrated Bars: 75, 80, 90, 100, and 150 ft-lbs (100, 110, 120, 135, 150 NM respectively)
• Torsion Bar Slip Design: Prevents bolt over-tightening; torque release occurs automatically at rated threshold
• Color-Coded for Speed: Black, yellow, red, blue, and orange finishes eliminate guesswork during busy service schedules
• Square Male Drive: Standard 1/2-inch or 3/8-inch drive compatibility (verify drive size with your torque wrench)
• Molded Carrying Case: Organized storage with individual recessed slots; protects bars and ensures team accountability
• Stamped/Printed Markings: Clear torque ratings and model identification on each bar shaft

Why Resellers Choose This Set

Margin Opportunity: Torque limiting bars are repeat-sale items. Once a shop integrates them into fastening protocols, they return for replacements as bars wear or are lost.

Turnkey Solution: The included carrying case removes excuses for poor torque discipline. One package, zero setup time for your customer.

Team Training Advantage: Color-coding reduces training burden. Technicians don't need to memorize torque values; they pick the color and go.

Liability Reduction: Shops using these bars document torque compliance. This shields your customers from warranty disputes and customer comebacks.

Passenger Car & Light Commercial Focus: Tight fit for the market segment with the highest volume and most predictable buying cycles.
