Value Collection MPC703121 Hex Cap Screw 3/8-24 Grade 8 25pk

Product Description

The VALUE COLLECTION MPC703121 is a Grade 8 steel hex head cap screw sized 3/8-24 x 2-1/2 inches, supplied in a pack of 25. It features a unified fine thread (UNF) form and partial threading along the shank. Grade 8 steel delivers high tensile strength suitable for demanding fastener applications in mechanical assemblies, equipment mounting, and structural connections. The uncoated finish keeps the fastener in bare steel condition, which is typical for applications where a coating is applied separately or where bare steel is specified. This screw conforms to ASME B18.2.1 dimensional standards, ensuring consistent head geometry and thread accuracy across the lot.

This hex head cap screw is used in general industrial, mechanical, and trade assembly work wherever a high-strength fine-thread fastener is required. Partially threaded shanks are preferred in applications requiring clamping force between two members without thread engagement in the grip zone. Typical install scenarios include equipment frames, flanged connections, motor mounts, and heavy-duty bracket assemblies. The 3/8-24 UNF thread is common in precision mechanical and automotive-adjacent applications. Each package contains 25 screws, making it appropriate for both single-job use and small-quantity stocking.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/8-24 UNF thread form for fine-pitch engagement and vibration resistance
• Partially threaded shank allows full grip-length clamping
• Uncoated bare steel finish for applications requiring a specific field-applied coating
• Meets ASME B18.2.1 dimensional standards for consistent fitment
• Sold in a pack of 25 for efficient small-quantity procurement

Compatibility

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

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 3/8-inch hex head cap screw. Torque to the fastener joint specification provided by the equipment manufacturer or applicable engineering standard for Grade 8 hardware. De-energize and lock out any equipment before fastener service work. Inspect thread engagement and mating surfaces for damage or contamination before assembly.
