Apex EX-250-B-3 Hex to Square Extension Bit 1/4 in

Product Description

The APEX EX-250-B-3 is a hex-to-square extension power screwdriver bit designed for use with power screwdrivers, impact drivers, and pneumatic tools in trade and industrial applications. It accepts a 1/4 inch hex drive input and provides a square drive output extension, allowing technicians to reach fasteners in confined or recessed locations. The overall length of 3 inches gives added reach without sacrificing torque transfer. At 0.05 pounds, the bit is lightweight and suitable for repetitive use. HVAC technicians, electricians, plumbers, and general mechanical contractors will find this bit useful when standard-length drivers cannot access tight panel or cabinet fasteners.

This bit is suited for residential and commercial service work where panel access, equipment installation, or cabinet assembly requires extended reach. It fits standard 1/4 inch hex quick-change chucks common on cordless and pneumatic power drivers. Typical applications include equipment panel fastening, electrical enclosure work, and mechanical assembly tasks where inline driver access is restricted by surrounding structure or components.

Installation Notes

Installation does not require electrical isolation, but always ensure the power tool is powered off and the trigger is locked before changing bits. Seat the hex shank fully into the chuck until the retention mechanism engages before applying torque. Inspect the bit for wear or deformation before use, as damaged bits can slip under load and damage fastener heads.
