Apex EX-370 Hex to Square Extension Bit 1-5/8 in

Product Description

The APEX EX-370 is a hex to square extension power screwdriver bit designed for use with power screwdriving equipment in professional assembly and fastening applications. Built with a pin lock retention feature, this bit maintains a secure connection between the drive tool and the fastener, reducing slippage and dropped sockets during high-speed operation. The 0.25-inch drive size and 1-5/8-inch overall length make it a compact, direct-fit solution for tight-clearance work. This type of extension bit is typically installed and used by electricians, HVAC technicians, plumbers, and general trade professionals who rely on power drivers for repetitive fastening tasks.

This extension bit is suited for residential and commercial trade applications where a hex shank power tool needs to interface with a square drive socket. The compact 1-5/8-inch overall length allows access in confined spaces common in panel work, equipment installation, and mechanical assembly. The pin lock design is particularly useful in overhead or angled fastening scenarios where socket retention is critical to workflow efficiency and safety.
