Proto J61406 Hex to Square Adapter Screwdriver Bit

Product Description

The PROTO J61406 is a hex to square adapter power screwdriver bit designed to convert a hex drive tool to a square drive output. This adapter bit allows technicians and tradespeople to use square drive sockets and accessories with hex-shank power tools and impact drivers. The J61406 features a 0.25 inch hex drive input and a 6 inch overall length, giving it sufficient reach for recessed fasteners and tight working envelopes. It is suited for assembly, service, and maintenance work across HVAC, electrical, plumbing, and general mechanical trades.

This adapter bit is a practical addition to any service kit where mixed drive systems are in use. The 6 inch length makes it useful in panel boxes, equipment cabinets, and other confined spaces where a standard-length bit or socket extension would not provide adequate clearance. It is intended for use with power screwdrivers and impact drivers equipped with a hex shank chuck, and pairs with square drive sockets for fastening applications.
