1/2 in. Drive Torque Limiting Extension
The Capri Tools CP30083-BAR100 is a 1/2 in. drive torque limiting extension bar rated at 100 ft. lbs. (135 Nm). It is designed for use with an impact wrench to deliver consistent torque accuracy on every fastener. Premium Chrome Molybdenum steel construction provides durability for professional automotive work. The 8 in. length includes a colour coded ring for quick identification.
Practical Limits of Impact Wrench Torque Control
An impact wrench alone cannot guarantee repeatable torque output, so this extension bar acts as a mechanical limiter to prevent overtightening. It absorbs excess energy once the 100 ft. lbs. threshold is reached, protecting wheel studs and other critical fasteners. The tool is calibrated for a single torque value and does not offer adjustable settings. Users must verify the required specification for each application before use.
Replaces Guesswork and Uncontrolled Impact
This bar replaces the practice of relying on impact wrench feel or unverified torque sticks that may exceed the target value. The jump is worth it when consistent 100 ft. lbs. torque is specified, such as on many lug nut applications, and when repeatable accuracy reduces comebacks. It does not suit jobs requiring different torque values or where a calibrated torque wrench is mandated.

Questions about this item
Is this the 100 ft. lbs. version or does Capri Tools make other torque limits for the same drive size?
This bar is the 100 ft. lbs. (135 Nm) model; Capri Tools offers additional torque-limiting extensions in different limits, each identified by its own colour-coded ring.
What does the 100 ft. lbs. rating actually do when I use the bar with my impact wrench?
The bar flexes internally once 100 ft. lbs. is reached, preventing the impact wrench from applying more torque so each fastener stops at the same value.
The bar has a 1/2 in. drive — does that limit the sockets or impact wrenches I can use with it?
Any 1/2 in. drive socket or impact wrench anvil will fit; the 1/2 in. square drive is the only interface specification for this tool.
