Value Collection 011201P Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 011201P is a hex socket cap screw designed for applications requiring a strong, compact fastener with a recessed drive. Manufactured from alloy steel with a black oxide finish, this screw provides corrosion resistance and a clean, low-profile appearance. The 5/16-18 UNC thread and 7/8-inch length under head make it suitable for precision assemblies where a flush or countersunk fastener profile is needed. It is installed with a 1/4-inch hex key drive and is fully threaded along its length. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, indicating it is rated for high-strength structural and mechanical applications. Machinists, millwrights, and maintenance technicians are the typical installers.

This screw is used across a wide range of industrial, mechanical, and light structural applications. Common use cases include securing machine components, fixtures, brackets, and assemblies where access space is limited and a socket-drive tool is preferred over a standard hex head. The fully threaded shank allows engagement along the entire fastener length, which is advantageous in thin-material or nut-driven installations. It is well suited for use in both original equipment manufacturing and field maintenance contexts.

Key Features

• 5/16-18 UNC thread for broad compatibility with standard inch-series tapped holes
• 7/8-inch length under head with full threading along the entire shank
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 1/4-inch hex socket drive accepts standard hex keys and socket bits
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard-dimension hex socket cap screw compatible with any 5/16-18 UNC tapped hole per ASME/ANSI B18.3 specifications.

Installation Notes

Installation is performed using a 1/4-inch hex key or T-handle driver; torque to the fastener specification appropriate for the joint material and class of fit per the applicable engineering standard. De-energize or lock out any equipment before replacing fasteners on operating machinery. Verify thread engagement depth in the mating part before final tightening to avoid stripping or under-engagement.
