Value Collection MP39360 Hex Cap Screw 3/8-24 X 2-1/2 in Grade 8

Product Description

The VALUE COLLECTION MP39360 is a partially threaded hex head cap screw designed for high-strength fastening in demanding mechanical and structural applications. Built from Grade 8 steel with a zinc yellow dichromate finish, this fastener delivers superior tensile strength and corrosion resistance compared to lower-grade alternatives. The 3/8-24 UNF thread profile provides fine-thread engagement suited to applications requiring precise torque control and vibration resistance. Conforming to ASME B18.2.1, this screw meets standardized dimensional and performance requirements relied upon by maintenance professionals, millwrights, and industrial mechanics across a wide range of assemblies.

This cap screw is suited for use in heavy equipment maintenance, industrial machinery assembly, automotive applications, and structural fabrication where Grade 8 strength is specified. The partially threaded shank allows for a bearing surface along the unthreaded portion, which is advantageous in applications requiring a close-tolerance fit or where shear loads are a primary concern. Sold in a package of 25 pieces, this item is appropriate for shop stock, field service kits, and production line use.

Key Features

• 3/8-24 UNF fine thread for precise torque control and vibration resistance
• Partially threaded shank supports shear load applications and close-fit assemblies
• Conforms to ASME B18.2.1 for standardized dimensional compliance
• Package quantity of 25 pieces for shop stock or field service use

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 3/8-24 UNF tapped hole or nut requiring a Grade 8 fastener per ASME B18.2.1 specifications.

Installation Notes

Installation is typically performed by mechanics, millwrights, or maintenance technicians using a standard hex wrench or socket set sized for a 3/8-24 fastener. Ensure mating threads are clean and free of debris before installation. Apply thread lubricant or thread-locking compound only as specified by the equipment manufacturer. Always torque to the value specified for Grade 8 fasteners in the applicable equipment service documentation.
