Wiha 71345 Hex Insert Bit 1/4 in Drive Impact Rated

Product Description

The WIHA 71345 is a hex screwdriver insert bit designed for use in 1/4 inch drive power tools, impact drivers, and bit holders. Built from steel and rated for impact use, this bit handles the torque demands of fastening and driving standard hex fasteners in professional trade applications. At 1 inch overall length, it fits standard quick-change chucks without extending tool reach. The impact rating means the steel is engineered to absorb the rotational shock generated by pneumatic and cordless impact drivers, reducing tip breakage and cam-out during high-cycle work. Electricians, HVAC technicians, plumbers, and general tradespeople use insert bits like this one as consumable tooling for daily fastening tasks.

This bit suits residential and commercial service work where 1/4 inch drive insert bits are the standard format. It fits bit holders, extension bars, and direct-chuck impact drivers. The standard hex fastener drive profile makes it appropriate for machine screws, cap screws, and hex-socket fasteners encountered in electrical panel work, equipment mounting, and mechanical assembly. Sold individually per unit, it is available in a package quantity of 10, making it practical to stock as a replacement supply item in a service van or shop.

Installation Notes

Insert bits should be seated fully into the bit holder or chuck before operating the tool. Inspect the bit tip for wear or deformation before each use, as a damaged tip increases the risk of fastener cam-out and stripped heads. No special tools or codes are required for bit replacement, but standard PPE including eye protection is recommended when operating impact drivers at high speed.
