Wera 05060155001 Power Screwdriver Bit 1/4 in Hex Square Recess

Product Description

The WERA 05060155001 is a square recess power screwdriver bit set designed for use with 1/4 inch hex drive power tools and impact drivers. This 4-piece set features bits with a 1-5/16 inch overall length and a 3.50 mm body diameter, sized for consistent seating in standard quick-change chucks. Square recess bits are a preferred choice for HVAC, electrical, and general mechanical work where Robertson-head fasteners are common. Licensed tradespeople and experienced technicians rely on these bits for repetitive fastening tasks where secure bit engagement and reduced cam-out matter.

These bits are suited for residential and light commercial installation work involving Robertson-head screws found in electrical boxes, HVAC equipment panels, ductwork, and general mechanical assemblies. The 1/4 inch hex shank is compatible with standard power screwdrivers, cordless drills, and impact drivers equipped with a 1/4 inch hex quick-change chuck. The 4-piece count makes the set practical for stocking a tool bag or service van kit.
