The APEX AM-2.5MM is a hex power screwdriver bit designed for use with power drivers and torque-controlled screwdriving equipment. It features a 2.5mm hex size and a 1/4-inch hex drive shank, making it compatible with standard power driver chucks used in production assembly, maintenance, and mechanical service work. The overall length of 1-15/16 inches suits inline and pistol-grip power drivers. Weighing just 0.017 pounds, this is a single-piece bit suited for M5 set screw applications where precise hex drive engagement is required.
This bit is appropriate for mechanical assembly, equipment maintenance, and general fastening tasks involving M5 set screws or similarly sized hex fasteners. It is commonly used by maintenance technicians, assembly line workers, and trade professionals who require reliable hex drive tooling in tight or repetitive fastening applications. The 1/4-inch drive shank fits standard quick-change bit holders found on most power screwdrivers and electric drivers.
Designed as a replacement or spare hex power screwdriver bit for use with standard 1/4-inch hex drive power screwdrivers and quick-change bit holders.
Insert the 1/4-inch hex shank fully into the power driver chuck or quick-change bit holder before operation. Ensure the driver is powered off or the trigger is locked before changing bits. Verify the hex size matches the fastener recess to avoid cam-out or fastener damage. This bit is intended for power driver use and should be matched to an appropriate torque setting for the application.
