Gibraltar SN-8-G Swivel Hex Nut 3/4-10 Unc Steel

Product Description

The GIBRALTAR SN-8-G is a 3/4-10 UNC swivel hex nut manufactured from steel with a black oxide finish. A swivel hex nut features a rotating pad that pivots to seat flush against angled or uneven surfaces, distributing clamp load without binding the fastener thread. This makes it a preferred choice for jigs, fixtures, workholding setups, and structural clamping applications in metalworking, fabrication, and general industrial use. The black oxide finish provides mild corrosion resistance and reduces surface glare. The part is sized with a 7/8-inch width across flats, stands 1 inch tall, and carries a 1/2-inch thread depth with a 1-inch swivel pad diameter. Sold as a single unit.

This swivel hex nut is well suited for machine shop fixtures, weld positioning setups, and tooling plates where fasteners must bear against non-perpendicular surfaces. It is also used in hydraulic press fixtures, manual clamps, and t-slot table setups. Its inch-series 3/4-10 UNC thread mates with standard threaded rods, studs, and clamp bolts commonly found in industrial clamping systems. Both professional machinists and maintenance technicians regularly use this style of nut when standard hex nuts would rock or apply uneven load.

Key Features

• Swivel pad pivots to compensate for angled clamping surfaces and reduce thread binding
• 3/4-10 UNC thread standard for compatibility with common inch-series threaded fasteners
• Steel construction provides durability under clamping and torque loads
• Black oxide finish offers mild corrosion resistance and low-glare appearance
• 1-inch swivel pad diameter distributes clamping force across a wider contact area
• Compact profile at 7/8-inch across flats and 1-inch overall height

Compatibility

Designed for use with standard 3/4-10 UNC threaded rods, studs, and bolts in inch-series industrial clamping and fixturing systems.

Installation Notes

Installation is performed by hand-threading onto a compatible 3/4-10 UNC stud or rod, then torquing with a standard 7/8-inch wrench. Ensure the swivel pad seats fully against the workpiece surface before applying final torque. De-energize or de-pressurize any associated machinery before adjusting fasteners in live fixturing setups. Follow applicable workplace safety and machinery guarding standards during installation.
