Diversitech 1937881 Reversible Magnetic Nut Driver 3 Pack

Product Description

The DIVERSITECH 1937881 is a 3-pack of reversible magnetic nut drivers designed for HVAC installation and service work. Each driver features a dual-tip socket that switches between 1/4-inch and 5/16-inch hex sizes without tools, covering the two most common sheet metal screw sizes found in ducted and ductless systems. The 2-3/4-inch shaft length suits confined equipment spaces. Sockets are forged from 6150 alloy steel and hardened above 48 HRC for durability under daily trade use. The 1/4-inch magnetic hex shank seats securely in any standard power drill or impact driver. Black oxide finish resists corrosion.

These nut drivers are suited for residential and light commercial HVAC work involving both ducted and ductless systems. The tapered socket design improves access in tight equipment cavities, junction boxes, and panel enclosures. The socket drives fasteners from the flats rather than the corners, which reduces cam-out and fastener damage during high-volume installation. The magnetic hex shaft allows quick bit changes and easy wipe-down when metal shavings or debris accumulate on the shank.

Key Features

• Reversible socket switches between 1/4-inch and 5/16-inch hex tip sizes
• Forged 6150 alloy steel sockets hardened above 48 HRC for strength and longevity
• Drives from the flats, not the corners, to minimize fastener slippage and cam-out
• Tapered socket profile improves access in tight spaces and equipment enclosures
• 1/4-inch magnetic hex shaft seats in standard drills and impact drivers; debris wipes off easily
• Meets or exceeds ASME B107.110 standards

Compatibility

Compatible with both ducted and ductless HVAC systems. Fits any drill or impact driver with a standard 1/4-inch hex chuck. Suitable for driving 1/4-inch and 5/16-inch hex-head sheet metal screws common in HVAC equipment installation and service.

Installation Notes

HVAC technicians should power down and lock out equipment before accessing panels or enclosures where fasteners are being driven or removed. Confirm the driver is fully seated in the chuck before applying torque. When using with an impact driver, verify the tool is set to an appropriate torque range to avoid stripping sheet metal screw heads.
