Value Collection 307110PR Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 307110PR is a hex socket cap screw designed for secure mechanical fastening in industrial and trade applications. Sized at 5/16-18 UNC with 1 inch of length under the head, this fastener is fully threaded and driven with a 7/32 inch hex key. It is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and a clean, low-reflectance appearance. Conforming to ASTM A574, it meets the strength and dimensional standards required for high-load fastening in machinery, equipment assembly, and structural fixturing. Licensed tradespeople and maintenance technicians across manufacturing and mechanical service trades rely on this grade of socket cap screw for consistent clamping performance.

This screw is suited for use in machinery assembly, equipment maintenance, jig and fixture construction, and general mechanical fastening where a recessed drive is preferred over an external hex head. The fully threaded shank allows engagement along the entire length, making it effective in thin-material applications and blind-hole installations. The black oxide finish makes it a common choice where a uniform dark appearance is required alongside adequate corrosion resistance in indoor or lightly protected environments.

• 7/32 inch hex socket drive accepts standard hex keys and bit drivers
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish provides moderate corrosion resistance and low-reflectance appearance
• Minimum order quantity of 100 pieces supports production and maintenance stocking needs

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 5/16-18 UNC tapped hole with 1 inch of thread engagement.

Installation Notes

Installation requires a 7/32 inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before driving. Apply appropriate thread lubricant or threadlocker per the assembly specification. Do not exceed the torque rating specified by the equipment manufacturer for this fastener size and grade.
