Value Collection 33633 Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 33633 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 and measures 7/8 inches under the head with full threading along its entire length. The fastener is manufactured from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection. The 5/16 inch hex drive allows installation with a standard hex key or socket driver. This screw is sized and rated for general-purpose industrial and mechanical use, and is commonly installed by machinists, millwrights, and general maintenance technicians.

This screw is suited for residential and commercial maintenance, machine assembly, fabrication, and repair work where a recessed drive fastener is required. The 3/8-16 UNC thread is a widely used coarse-thread specification compatible with standard tapped holes in steel, aluminum, and other metals. The fully threaded shank maximizes thread engagement across the entire grip length, making it appropriate for through-hole and shallow tapped applications alike.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded shank for maximum thread engagement
• 5/16 inch hex socket drive for use with hex keys or socket drivers
• Alloy steel construction for high tensile strength
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard replacement or stock fastener for any application requiring a 3/8-16 UNC hex socket cap screw with a 7/8 inch length under head.

Installation Notes

Installation is performed using a 5/16 inch hex key or T-handle driver. Ensure the receiving tapped hole is clean and free of debris before driving. Power down or de-energize any equipment before replacing fasteners on live assemblies. Follow applicable ASME or equipment manufacturer torque specifications for the 3/8-16 thread size based on material and joint requirements.
