Wera 05057471001 Screwdriver Insert Bit Set 19 Piece

Product Description

The WERA 05057471001 is a 19-piece screwdriver insert bit set designed for professional tradespeople who need a broad range of drive types in a single kit. The set covers five point types: Hex-Plus, Phillips, Pozidriv, Slotted, and Torx, making it a versatile bench or bag addition for electricians, HVAC technicians, plumbers, and general service pros. It includes a stubby bit holder (811/1) and spans Hex-Plus sizes from 2 to 5.5 mm, Phillips sizes 1 and 2, Pozidriv sizes 1 and 2, Slotted sizes, and Torx profiles. The compact packaging measures 4.53 x 3.94 x 2.36 inches and weighs 0.59 pounds.

This bit set is suited for residential and light commercial service work where a technician encounters mixed fastener types across panels, equipment covers, terminal blocks, and mechanical assemblies. The 811/1 stubby bit holder expands usability in tight access situations common in control panel work, junction boxes, and equipment cabinets. The variety of included drive types reduces the need to carry multiple individual bit sets on a service call.

Installation Notes

Insert bits should be seated fully into the bit holder before applying torque to avoid cam-out or bit damage. Inspect bits for wear regularly, especially on Pozidriv and Phillips profiles where tip geometry directly affects fastener engagement. Store the set in its tray or case to prevent bit mixing and loss. No special tools or trade licensing are required for use, though application in electrical panels should follow applicable NEC lockout/tagout procedures.
