Bsc Preferred QJDIB-NS-002 Magnetic Nut Driver Bit

Product Description

The BSC PREFERRED QJDIB-NS-002 is a 5/16-inch magnetic nut driver bit sized at 1-7/8 inches in length, built for use with impact drivers and standard drill drivers. An industrial-strength internal magnet holds hex nuts and fasteners firmly on the bit, reducing drop risk and improving placement accuracy in tight spaces. The bit is constructed to resist torque stress under repeated impact loads, making it suitable for high-cycle fastening tasks on job sites where downtime is not an option. Licensed electricians, plumbers, HVAC technicians, and general contractors reach for this style of bit when driving sheet metal screws, hex-head fasteners, and equipment panel hardware.

This nut driver bit is appropriate for light commercial and residential trade work. It fits standard 1/4-inch hex shank impact drivers and drill drivers commonly used across the electrical, HVAC, and mechanical trades. The 5/16-inch drive size suits the hex fasteners found on electrical panels, ductwork flanges, equipment covers, and structural connectors. Sold individually, it integrates easily into an existing bit set or serves as a direct replacement for a worn or lost bit.

Key Features

• 5/16-inch drive size for hex nuts and fasteners common in trade applications
• 1-7/8-inch overall length provides reach in recessed or obstructed fastener locations
• Industrial-strength magnet retains nuts on the bit during placement
• Torque-resistant construction rated for use with impact drivers
• Fits standard 1/4-inch hex shank impact and drill drivers

Compatibility

Designed as a standard 1/4-inch hex shank nut driver bit compatible with impact drivers and drill drivers that accept 1/4-inch quick-change hex tooling.

Installation Notes

This bit is installed and removed by hand into any 1/4-inch hex quick-change chuck. Confirm the chuck is fully seated and locked before driving under impact load. Inspect the bit for wear, cracking, or magnet degradation before each use and replace if the hex profile shows rounding. Follow applicable NEC or trade-specific fastener torque requirements for the assembly being worked on.
