MIDWEST FASTENER CORP 03737 Hex Nut 3/4"-16 Steel Grade 8 Zinc Yellow 10 PK

3/4"-16 Grade 8 Hex Nuts

These 3/4"-16 hex nuts are made from Grade 8 steel with a zinc yellow finish. The pack contains 10 pieces for securing bolts and machine screws in automotive and industrial assemblies. Builders and mechanics use them where high-strength fastening is required. They suit applications that demand a durable, corrosion-resistant fastener.

Coarse-thread limit

The 3/4"-16 thread is a coarse series, so it resists stripping in softer materials but offers less fine adjustment than a fine-pitch alternative. Grade 8 strength handles heavy clamping loads, yet the zinc yellow coating provides only moderate corrosion protection in harsh environments. Users needing stainless steel or a finer pitch must select a different product. The nuts are not suited for applications that require lock-nut features or prevailing torque.

Simple wrench installation

Installation is straightforward with a standard wrench or socket that matches the hex size. The main issue is cross-threading if the bolt is not started straight, which can damage both threads. Over-torquing can stretch the bolt beyond its yield point despite the nut's high grade. Always verify thread pitch matches the mating part before assembly.
