Why this one

Hammer-strike loosening power

This manual screwdriver bit set converts the force of a hammer blow into high-torque rotation on contact, generating the controlled burst needed to break free corroded, seized, or overtightened fasteners.

Four fastener profiles

The included 5/16 inch hex drive bits cover Flat, Phillips, Hex, and Torx profiles, so one compact impact driver set handles the most common recessed-head fasteners found in engine bays, machinery panels, and equipment housings.

Reversible mechanism

A built-in directional selector switches between counterclockwise loosening and clockwise tightening without removing the tool from the fastener.

17 impact-rated bits

Every one of the 17 impact bits included is rated for impact duty, meaning they are designed to absorb the sudden torque spike of a hammer strike without cracking or chipping.

TT1 tray organization

All 20 pieces nest into a purpose-molded TT1 tool tray that integrates directly into Teng Tools roller cabinets, top boxes, and portable cases.
