Value Collection MP39060 3/8-16 X 2-1/2 in Grade 8 Hex Cap Screw

Product Description

The VALUE COLLECTION MP39060 is a Grade 8 steel hex head cap screw with a 3/8-16 UNC thread and a 2-1/2-inch length under head. It features partial threading and a zinc yellow dichromate finish that provides corrosion resistance in demanding environments. Manufactured to ASME B18.2.1 standards, this fastener delivers the high tensile strength required in structural, mechanical, and heavy equipment assemblies. Installers across HVAC, plumbing, electrical, and general mechanical trades reach for Grade 8 hardware when joint integrity under load and vibration is a priority. Sold in a package of 25 pieces.

This cap screw is suited for bolted connections in ferrous and non-ferrous assemblies where a standard UNC thread pitch and partial threading are specified. The hex head design accommodates standard open-end, box-end, and socket wrenches, making it practical in confined spaces common to mechanical and equipment installations. The zinc yellow dichromate finish meets general-purpose corrosion resistance requirements for indoor and light-duty outdoor applications. Grade 8 classification indicates a minimum proof load appropriate for high-stress fastening applications.

Installation Notes

Installation is performed by mechanical and general trade technicians using standard hand or power tools rated for the fastener size. Always verify mating thread condition and thread engagement depth before torquing. Do not mix Grade 8 hardware with lower-grade nuts or threaded inserts, as this can compromise joint integrity. Follow applicable equipment manufacturer specifications and relevant codes for torque requirements and joint design.
