Diversitech 1937888 Reversible Magnetic Nut Driver 4 in 30 Pack

Product Description

The DIVERSITECH 1937888 is a 30-pack counter display of 4-inch reversible magnetic nut drivers designed for HVAC and mechanical trade professionals. Each driver features a high-performance socket that drives fasteners from the flats rather than the corners, reducing slippage and fastener damage. The socket reverses between 1/4-inch and 5/16-inch tip sizes, covering the two most common hex fastener sizes found in HVAC equipment. The 1/4-inch magnetic hex shaft sheds metal shavings and debris with a simple wipe. Sockets are forged from 6150 alloy steel and hardened above 48 HRC for strength and durability. The driver meets or exceeds ASME B107.110 standards.

These nut drivers are suited for residential and commercial HVAC installation and service work, including both ducted and ductless system applications. The tapered socket design improves access in tight spaces common in air handler cabinets, condenser panels, and equipment enclosures. The 4-inch shaft length suits general-purpose fastening tasks. The counter display pack of 30 is sized for distributor counters and supply house point-of-sale placement, making it a practical stocking item for trade supply locations.

Key Features

• Reversible socket switches between 1/4-inch and 5/16-inch tip sizes without a tool change
• Drives from fastener flats, not corners, to minimize cam-out and fastener damage
• Tapered socket design for improved reach in confined spaces
• 1/4-inch magnetic hex shaft — metal debris wipes off cleanly
• 6150 alloy steel construction hardened above 48 HRC
• Meets or exceeds ASME B107.110 standards
• Black oxide finish; color-coded red and yellow for quick tip-size identification

Compatibility

Designed for use on ducted and ductless HVAC systems. The 1/4-inch hex shank is compatible with standard power drills, impact drivers, and nut driver handles accepting 1/4-inch hex bits.

Installation Notes

HVAC technicians and installers are the primary users of this tool. Always de-energize equipment before accessing fastened panels or covers. Inspect the magnetic tip for retained metal debris before each use to avoid contaminating electrical components. Follow applicable NEC and equipment manufacturer guidelines when working inside energized enclosures.
