Value Collection MP39327 Hex Cap Screw 5/16-24 X 3/4 in Grade 8

Product Description

The VALUE COLLECTION MP39327 is a fully threaded hex head cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade 8 steel, this fastener delivers a higher tensile and proof load than Grade 5 hardware, making it appropriate where joint integrity under load is critical. The zinc yellow dichromate finish provides corrosion resistance and is identifiable by its characteristic yellow iridescent coating. Thread size is 5/16-24 UNF with a 3/4-inch length under head. Conforms to ASME B18.2.1 standards. Sold in a package of 50 pieces.

This fastener is used across a wide range of applications including machinery assembly, automotive components, hydraulic and pneumatic equipment mounting, and general fabrication where a fine-thread, high-strength hex cap screw is required. The 5/16-24 UNF thread pitch is commonly specified where vibration resistance or finer torque adjustment is needed compared to coarse-thread equivalents. Suitable for use in production shops, maintenance facilities, and field service environments by machinists, millwrights, mechanics, and general tradespeople.

Key Features

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 5/16-24 UNF fully threaded fastener conforming to ASME B18.2.1 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using the appropriate hex wrench or socket. Always verify that the mating thread material and grade are compatible with Grade 8 fastener requirements before installation. Do not mix inch and metric fasteners in the same joint. Apply torque in accordance with the equipment manufacturer's specifications for the joint being assembled.
