Gibraltar SN-2-G Swivel Hex Nut 1/4-20 Unc Steel

Product Description

The GIBRALTAR SN-2-G is a swivel hex nut designed for 1/4-20 UNC threaded applications where a standard fixed nut cannot make full contact with an angled or irregular surface. The swivel pad pivots to self-align, distributing clamping load evenly without distorting the workpiece. Machined from steel with a black oxide finish for corrosion resistance, this nut measures 5/16 inches across the flats, 13/32 inches in overall height, and 3/16 inches of thread depth. The 3/8-inch diameter swivel pad provides a stable bearing surface. It is installed by maintenance technicians, machine builders, and industrial tradespeople wherever secure, adjustable clamping is required.

This swivel hex nut is suited for fixturing, clamping, and assembly applications where mating surfaces are not perfectly perpendicular to the fastener axis. Common uses include jig and fixture builds, machine guarding, structural clamping in fabrication shops, and general mechanical assembly. The black oxide finish makes it appropriate for light-duty indoor environments where mild corrosion protection is needed. The inch-based 1/4-20 UNC thread makes it compatible with standard American fastener hardware widely used across manufacturing and trade work.

Key Features

• Swivel pad self-aligns to uneven or angled clamping surfaces
• 1/4-20 UNC thread for compatibility with standard inch-series hardware
• Steel construction for durability under clamping loads
• Black oxide finish provides mild corrosion and abrasion resistance
• 3/8-inch diameter pad distributes bearing load across the contact surface
• Compact profile: 5/16 inches wide, 13/32 inches tall, 3/16 inches thread depth

Compatibility

Designed for use with 1/4-20 UNC inch-series threaded rods, bolts, and studs in standard American fastener assemblies.

Installation Notes

Installation requires only standard wrenches or sockets sized for a 5/16-inch hex. Ensure the mating threaded component is clean and free of debris before threading the nut. The swivel pad should be allowed to float freely to self-seat against the clamping surface. De-energize or lock out any machinery before performing fastener work on live equipment per applicable safety standards.
