Klein Tools 8660110 Magnetic Hex Driver 5/16 in 1/4 in Drive

Product Description

The KLEIN TOOLS 8660110 is a magnetic hex driver designed for driving sheet metal screws in HVAC, electrical, and light fabrication work. It features a 1/4 inch hex shank with a quick-release groove for fast bit changes, and a 5/16 inch socket end sized for standard sheet metal screw heads. Strong rare earth magnets hold fasteners securely during placement, reducing dropped screws in tight spaces. Overall length is 1.75 inches. The size is engraved directly on the tool for quick identification in a crowded pouch or bag.

This driver is a go-to for HVAC technicians and electricians installing ductwork, electrical enclosures, junction boxes, and sheet metal panels. The 1/4 inch drive shank is compatible with standard hex-drive power tools and manual nut drivers. The compact 1.75 inch length suits confined spaces where longer drivers cannot reach or maneuver. Suitable for residential and light commercial service work where sheet metal screw installation is routine.

Installation Notes

Installed and used by HVAC technicians and electricians in standard sheet metal fastening applications. Ensure the quick-release groove is fully engaged in the tool holder before driving fasteners under load. Magnetic drivers should be kept away from sensitive electronic components or magnetic media that could be affected by rare earth magnets.
