Value Collection D39360 Hex Cap Screw 3/8-24 X 2-1/2 in Grade 8

Product Description

The VALUE COLLECTION D39360 is a 3/8-24 hex head cap screw designed for high-strength fastening applications where vibration resistance and load integrity matter. Manufactured from Grade 8 steel, this fastener delivers significantly higher tensile and proof load ratings than standard Grade 5 hardware. The zinc yellow dichromate finish provides a corrosion-resistant barrier suitable for general industrial and mechanical assemblies. At 2-1/2 inches under the head with partial threading, it allows for a full bearing grip in the unthreaded shank zone, making it appropriate for applications requiring precise clamping force without thread engagement along the full length. Machinists, millwrights, and maintenance technicians are the primary installers.

This screw is suited for structural and mechanical fastening in industrial equipment, automotive assemblies, heavy machinery, and general fabrication where UNF fine-thread engagement and high-strength steel are specified. The 3/8-24 UNF thread series offers finer thread pitch than coarse equivalents, providing better torque control and holding power in applications involving thin materials or precision-fit joints. The partial threading allows the unthreaded shank to serve as a locating or shear surface in bolted connections.

Key Features

• Grade 8 steel construction for high tensile and proof load strength
• 3/8-24 UNF fine-thread series for precise torque control and strong thread engagement
• Partially threaded shank provides a clean bearing surface for shear and clamping applications
• Zinc yellow dichromate finish offers corrosion resistance in general service environments
• Conforms to ASME B18.2.1 dimensional standards for consistent fitment with standard hex tooling

Compatibility

Designed as an ASME B18.2.1 standard hex head cap screw in 3/8-24 UNF thread, compatible with standard 3/8-24 UNF nuts, inserts, and tapped holes requiring Grade 8 strength fasteners.

Installation Notes

Install with appropriate hex wrench or socket rated for Grade 8 fastener torque requirements per applicable engineering specifications. Ensure mating threads are clean and free of debris before installation. Do not mix Grade 8 fasteners with lower-grade nuts or inserts, as this can compromise joint integrity. Follow applicable ASME or equipment manufacturer torque tables for 3/8-24 UNF hardware.
