Capri Tools 1/2 in. Drive Torque Limiting Extension Bar — 8 in., 100 ft·lbs preset, Cr-Mo steel

Capri Tools 1/2 in. Drive Torque Limiting Extension Bar is an 8-inch Chrome Molybdenum extension that limits output to 100 ft·lbs for consistent torque when using impact wrenches.

When you’re fastening with an impact tool, over-torquing can damage threads, hardware, or assemblies. This Capri Tools torque limiting extension bar sits between your impact wrench and socket to mechanically cap the applied torque at 100 ft·lbs (135 Nm), producing repeatable results without changing your wrench settings. Built from premium Chrome Molybdenum steel and finished for workshop use, it’s a compact solution for assembly, maintenance, and repair jobs where consistent torque matters.

How does this extension bar prevent overtightening?

The tool uses an internal slip mechanism that disengages once the preset torque threshold is reached. Instead of transmitting additional rotational force, it allows controlled slipping so the fastener doesn’t see excess torque. This mechanical approach works with impact wrenches, removing guesswork from repetitive fastening tasks.

• Preset torque limit: 100 ft·lbs (135 Nm)
• Mechanical slip design for repeatable stops
• Works inline with standard 1/2 in. drive impact wrenches
• No electronic calibration or batteries required

Will it fit my tools and fasteners?

The extension bar is designed for 1/2-inch drive sockets and most commercial impact wrenches. Its 8-inch length gives extra reach while keeping control over torque transfer. Color coding on the ring helps you identify the torque rating quickly in a busy toolbox or tool cart.

• Drive size: 1/2 in. compatible with standard sockets
• Length: 8 in. for added access to recessed fasteners
• Color-coded ring for fast identification in sets
• Made to pair with common impact wrench models

What materials and durability features does it have?

Manufactured from Chrome Molybdenum (Cr-Mo) alloy, the extension bar offers high strength and wear resistance under impact loading. The finish resists corrosion and workshop grime, while the internal mechanism is engineered for repeated cycles at the rated torque. These choices help the tool stay reliable through daily garage or shop use.

• Chrome Molybdenum steel construction for toughness
• Durable finish to resist rust and abrasion
• Internal components rated for repeated use at 100 ft·lbs
• Built for professional and DIY environments

How should I use it safely and get best results?

Install the extension between your impact wrench and socket, then operate the wrench as usual. Stop once the bar slips—this indicates the torque limit has been reached. For accuracy, use clean sockets and confirm drive engagement; do not exceed the rated torque by forcing the tool.

• Attach between impact wrench and socket securely
• Run impact until slipping signals torque stop
• Keep sockets and drives clean for reliable engagement
• Do not use to measure torque—use calibrated torque tools for verification

Who is this for: This Capri Tools torque limiting extension bar is aimed at mechanics, fleet technicians, fabricators, and serious DIYers who use impact wrenches and need consistent, repeatable torque without changing wrench settings. It’s ideal for assembly lines, maintenance bays, and home shops where preventing overtightening saves time and protects components.
