Hillman Fasteners 150021 Hex Nut 5/8-11 Coarse Thread 25 Pack

Product Description

The HILLMAN FASTENERS 150021 is a 5/8-11 coarse thread hex nut made from zinc plated steel, sold in a 25-pack. This standard hex nut provides reliable threaded fastening for structural, mechanical, and general trade applications. The zinc plating adds corrosion resistance for use in both interior and exterior environments. Each nut conforms to the 5/8-11 UNC thread standard, making it compatible with commonly available 5/8-inch coarse thread bolts and threaded rod. Licensed tradespeople and contractors rely on this hardware for equipment mounting, structural assembly, and general utility connections across HVAC, plumbing, and electrical installations.

These hex nuts are suited for residential and commercial construction and maintenance work. The 5/8-11 coarse thread pattern is widely used in structural steel connections, equipment bases, conduit supports, and mechanical equipment anchoring. The 25-pack quantity is practical for service vans and job-site supply, reducing the need for frequent restocking on multi-point fastening tasks. Suitable for indoor and light outdoor use where mild corrosion resistance is required.

Installation Notes

Installation is performed by hand-threading onto a compatible 5/8-11 coarse thread fastener, then tightening with an appropriately sized wrench or socket. Ensure mating threads are clean and free of debris before assembly. Follow applicable mechanical or structural codes for torque requirements specific to the connection type and load rating. Zinc plated hardware is not recommended for highly corrosive or submerged environments where stainless or hot-dip galvanized fasteners would be more appropriate.
