Value Collection 33636 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 33636 is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies, fixtures, and equipment. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and moderate corrosion resistance in indoor and light industrial environments. The 3/8-16 UNC thread pattern is a standard coarse-thread designation widely used across North American trade and industrial applications. Drive size is 5/16 inch hex, accommodating a standard Allen or hex key. Overall length under head is 1-1/2 inches with full threading along the shank. Meets ASME/ANSI B18.3 and ASTM A574 standards.

This screw is suited for machine assembly, equipment mounting, and structural fastening tasks where a recessed drive head is required for flush or countersunk installations. The coarse 3/8-16 UNC thread engages quickly and resists cross-threading in field conditions. Typical installers include millwrights, HVAC fabricators, pipefitters, and maintenance technicians working on equipment panels, brackets, and component mounting. The black oxide coating reduces surface glare and provides light corrosion inhibition, making it appropriate for dry or lightly oiled assemblies.

Key Features

• 3/8-16 UNC coarse thread for fast engagement and wide compatibility with standard tapped holes
• 5/16 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 1-1/2 inch length under head with full threading along the entire shank
• Alloy steel construction for high tensile strength and load-bearing capacity
• Black oxide finish provides light corrosion resistance and low-glare appearance
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard OEM-style replacement or new-installation fastener for any application requiring a 3/8-16 UNC hex socket cap screw with a 1-1/2 inch length under head.

Installation Notes

Install using a 5/16 inch hex key or Allen bit driver rated for the required torque. Confirm the receiving thread is clean and free of debris before driving to avoid galling or cross-threading. Follow applicable torque specifications from the equipment manufacturer or relevant ASME standards for 3/8-16 alloy steel fasteners. Do not use impact drivers without a torque-limiting socket to avoid overstressing the socket head.
