Apex EX-501-2 Hex to Square Extension Bit 2 Inches

Product Description

The APEX EX-501-2 is a hex to square extension power screwdriver bit designed for use with power tools and impact drivers requiring a transition between drive types. With a 7/16-inch hex shank input and a square drive output, this bit bridges hex-drive tool holders to square-drive sockets and accessories. The pin lock retention feature secures the bit during operation, reducing the chance of slippage or dropout under torque. At 2 inches overall length, it provides a compact reach suitable for tight-clearance fastening work. This bit ships as a single piece and is suited for use by electricians, HVAC technicians, plumbers, and general trade professionals who rely on power screwdrivers or impact-rated bit holders.

This extension bit is appropriate for residential and light commercial service work where a hex-to-square drive conversion is needed at the tool. It fits into standard power screwdriver and impact driver bit holders with a 7/16-inch hex input, then accepts square-drive sockets or accessories on the output end. The pin lock design makes it practical in overhead or vertical fastening positions where bit retention is critical. Typical applications include panel work, equipment assembly, and general mechanical fastening tasks.

Installation Notes

Installation is performed by trade professionals using power screwdrivers or impact drivers with compatible hex bit holders. Verify that the tool holder is rated for the drive size before use. Engage the pin lock fully before applying power to prevent bit ejection. Inspect the bit for wear or damage before each use, and replace if the drive surfaces show rounding or deformation.
