Value Collection R50000115 Hex Nut 1-1/8-12 Grade 8

Product Description

The VALUE COLLECTION R50000115 is a Grade 8 steel hex nut with a 1-1/8-12 UNF thread profile and a zinc yellow dichromate finish. Designed for high-strength fastening applications, this nut delivers the clamping force and corrosion resistance required in demanding mechanical and structural assemblies. The zinc yellow dichromate coating provides a baseline level of corrosion protection while meeting standard finishing requirements for Grade 8 hardware. At 0.4 pounds, it is a solid, heavy-duty fastener suited for use where standard Grade 5 hardware is insufficient. Tradespeople and maintenance professionals working on industrial equipment, heavy machinery, or structural connections will find this a reliable standard-specification nut.

This hex nut is appropriate for use in mechanical maintenance, equipment assembly, and structural fastening applications where UNF thread engagement and Grade 8 strength ratings are specified. The right-hand thread direction follows standard convention, making it compatible with the vast majority of threaded rod, bolt, and stud configurations encountered in trade and industrial settings. It is commonly installed by millwrights, maintenance mechanics, and general contractors working on equipment frames, mounting brackets, and load-bearing assemblies.

Key Features

• Grade 8 steel construction for high-strength fastening requirements
• 1-1/8-12 UNF right-hand thread for standard engagement
• Zinc yellow dichromate finish for corrosion resistance
• 1-11/16 inches (1.6875 inches) across flats for standard wrench sizing
• 31/32 inch height for proper thread engagement depth

Compatibility

Designed as a standard-specification replacement or supplemental fastener for any application requiring a 1-1/8-12 UNF Grade 8 hex nut with a zinc yellow dichromate finish.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with high-strength fastener specifications. Always ensure mating threads are clean, undamaged, and properly lubricated before installation. Use a calibrated torque wrench and follow the torque specifications outlined in the equipment manufacturer's service documentation for Grade 8 fasteners of this thread size. Never substitute a lower-grade nut in applications where Grade 8 is specified.
