The L H Dottie Co 5HN34 is a Grade 5 hex nut threaded to 3/4 inch-10 UNC specifications. It is a standard six-sided fastener used to secure bolts, rods, and threaded hardware in structural and mechanical assemblies. Grade 5 designation indicates a medium-strength carbon steel nut that meets recognized SAE performance standards for tensile and proof load requirements. Electricians, HVAC technicians, plumbers, and general contractors use this nut wherever a reliable, load-bearing threaded connection is required in trade installations.

This hex nut is suited for use in residential and light commercial construction, equipment mounting, panel support structures, conduit strut systems, and similar hardware applications.

Installation Notes

Installation is performed by hand-starting the nut onto the mating threaded fastener, then tightening with an appropriately sized wrench.
