Value Collection 872265PR Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 872265PR is a hex socket cap screw designed for secure mechanical fastening in structural and machine assembly applications. It features a 3/8-16 UNC thread size and a 5/16 inch internal hex drive, requiring an Allen key or hex bit for installation. The 2.25 inch length under head and partial threading allow for strong clamping force in bolted joint assemblies. Manufactured from alloy steel with a zinc-plated finish, this fastener resists corrosion in moderate-exposure environments. It conforms to ASME B18.8 and ASTM A574 standards, making it suitable for demanding mechanical and industrial fastening work.

This cap screw is suited for use in general industrial machinery, fabricated metal assemblies, maintenance and repair operations, and light structural connections. Partial threading is appropriate for applications requiring a shoulder length or where the fastener passes through a clearance hole before engaging a tapped hole. It is commonly installed by machinists, millwrights, and maintenance technicians in both production and field settings.

Key Features

• 3/8-16 UNC thread for reliable engagement in standard tapped holes
• 5/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 2.25 inch length under head, partially threaded for clearance-hole applications
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Zinc-plated finish provides moderate corrosion resistance
• Conforms to ASME B18.8 dimensional standards

Compatibility

Designed as a standard replacement or service fastener for any application requiring a 3/8-16 UNC partially threaded hex socket cap screw with a 2.25 inch length under head, conforming to ASME B18.8 and ASTM A574 specifications.

Installation Notes

Installation requires a 5/16 inch hex key or Allen-style bit driver rated for the applicable torque. Ensure the mating tapped hole is clean, free of debris, and cut to 3/8-16 UNC specification before driving the fastener. Always torque fasteners according to the equipment manufacturer's specifications for the joint material and application. De-energize or lock out any machinery before servicing fasteners on moving or pressurized assemblies.
