The WERA 05060427001 is a magnetic nutsetter power screwdriver bit designed for use with power drivers and impact-rated screwguns in professional trade applications. Measuring 2 inches in overall length with a 1/4 inch hex drive, this bit accepts 12mm hex fasteners and relies on its integrated magnetic tip to retain nuts and bolts securely during driving. The 1/4 inch drive shank seats directly into standard power bit holders, quick-release chucks, and bit extensions common on cordless and corded screwguns. Electricians, HVAC technicians, plumbers, and general contractors reach for magnetic nutsetters when driving sheet metal screws, hex-head bolts, or equipment fasteners in tight or overhead locations where dropped hardware is a problem.
This nutsetter suits residential and light commercial work wherever a 12mm hex fastener is driven repetitively. Typical applications include ductwork and equipment panel assembly in HVAC installations, electrical enclosure hardware, plumbing bracket fasteners, and general mechanical assembly. The 2-inch overall length provides clearance from surfaces without excessive flex, making it a practical everyday-carry bit for service technicians and installers working out of a van or tool bag.
Designed as an OEM-style power bit for use with any 1/4 inch hex drive power tool, screwgun, or bit holder accepting standard 2-inch insert bits.
Install this bit into a 1/4 inch quick-release chuck or bit holder before applying power. Ensure the chuck fully seats and locks around the hex shank before driving. Match the 12mm nutsetter to the fastener head before driving to avoid rounding. Replace the bit if the magnetic tip loses retention strength or the hex shank shows visible wear or deformation.
