Apex EX-250 Hex to Square Extension Bit 1-3/8 in

Product Description

The APEX EX-250 is a hex to square extension power screwdriver bit designed for use with power screwdrivers and impact drivers in professional trade and industrial assembly applications. With a 1/4-inch hex drive and an overall length of 1-3/8 inches, this bit provides a compact, rigid connection between a power tool and a square drive socket or adapter. The pin lock design secures the bit during operation, reducing the chance of slippage or bit ejection under load. It is suited for licensed electricians, HVAC technicians, plumbers, and other tradespeople who work with power-driven fastening tools daily.

This bit is intended for use in environments where a hex shank drive tool needs to interface with a square drive accessory. The short overall length makes it appropriate for tight-clearance applications where a longer extension would interfere with surrounding components or panels. It is a single-piece unit sold individually, making it a straightforward replacement or addition to an existing bit set in a service vehicle or tool bag.

Installation Notes

Installation is performed by tradespeople using standard 1/4-inch hex chuck power drivers or impact tools. Ensure the tool is powered off and the trigger is locked before inserting or removing the bit. Verify the pin lock is fully engaged before applying load to prevent bit disengagement during fastening. Inspect the bit for wear or deformation before each use and replace if the drive surfaces show rounding or cracking.
