Apex 185-2MM Hex Insert Bit 1/4 in Drive 1 in Oal M2.5

Product Description

The APEX 185-2MM is a hex screwdriver insert bit designed for use with 1/4 inch drive power tools and manual bit holders. Machined from steel, this bit measures 1 inch in overall length and is sized for M2.5 metric cap screws. The standard insert format fits the most common quick-change and power screwdriver systems used in mechanical assembly, HVAC equipment installation, and electrical panel work. At 0.01 pounds, it is a compact, single-piece consumable intended for repetitive fastening tasks where a dedicated hex bit keeps work moving without tool changes.

This insert bit is suited for residential and light commercial trade applications where M2.5 metric fasteners appear on equipment covers, control boards, junction boxes, and terminal enclosures. HVAC technicians, electricians, and general mechanical contractors will find it useful during equipment installation and service calls. The 1/4 inch drive shank is compatible with standard power screwdriver chucks and manual bit holders commonly found in trade tool kits.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or bit damage. Always de-energize equipment and follow applicable NEC or equipment manufacturer lockout procedures before accessing fastened covers or enclosures. Inspect the bit tip for wear or rounding before use, as a damaged tip can strip M2.5 fastener heads. This bit is intended for manual or low-speed power driver use typical of trade service work.
