Value Collection 30255 Hex Head Cap Screw 7/16-20 Grade 5

Product Description

The VALUE COLLECTION 30255 is a fully threaded hex head cap screw designed for general-purpose mechanical fastening in trade and industrial applications. Sized at 7/16-20 UNF with a 1-1/4 inch length under head, this fastener is manufactured from Grade 5 steel with a zinc-plated finish for corrosion resistance. Conforming to ASME B18.2.1, it meets the dimensional and strength standards required for structural and equipment assembly work. This package contains 100 pieces, making it a practical stocking item for service trucks, maintenance shops, and job sites. HVAC, plumbing, and electrical tradespeople commonly use Grade 5 UNF fasteners when assembling equipment frames, mounting brackets, and panel components.

This screw is suited for residential and light commercial mechanical applications where a fine-thread UNF fastener is required. The 7/16-20 thread pitch is commonly specified in equipment assemblies that demand tighter thread engagement than a coarse UNF alternative provides. The zinc-plated finish offers a baseline level of corrosion protection appropriate for indoor and sheltered outdoor installations. Sold in a quantity of 100, this SKU supports bulk stocking for recurring fastener needs on service and installation jobs.

Compatibility

Designed as a standard UNF hex head cap screw suitable for use in any application requiring a 7/16-20 fully threaded Grade 5 fastener conforming to ASME B18.2.1.

Installation Notes

Install using a standard hex wrench or socket driver sized for a 7/16-inch hex head cap screw. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque range for Grade 5 steel fasteners as specified by the equipment manufacturer. Always follow applicable mechanical codes and equipment service documentation when replacing or installing fasteners in pressurized or load-bearing assemblies.
