Value Collection -33614-1 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION -33614-1 is a fully threaded hex socket cap screw designed for general mechanical fastening applications. Sized at 5/16-18 UNC with a 3/8-inch length under head, this fastener uses a 1/4-inch hex drive and is manufactured from alloy steel with a black oxide finish for added corrosion resistance. Compliant with ASME/ANSI B18.3 and ASTM A574 standards, it is suited for use in structural assemblies, machinery, and equipment maintenance where a reliable, high-strength fastener is required. Each package contains 50 screws.

This screw is appropriate for a wide range of industrial and mechanical applications including HVAC equipment assembly, electrical enclosure fastening, plumbing fixture mounting, and general equipment repair. The black oxide coating reduces light reflection and provides mild surface protection in indoor environments. The 1/4-inch hex socket drive allows use with a standard Allen key or hex bit driver, making it accessible in tight clearance areas where conventional fastener heads cannot be used.

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw suitable for use in any application requiring an ASME/ANSI B18.3 compliant fastener with a 3/8-inch length under head and 1/4-inch hex drive.

Installation Notes

Installation is performed with a 1/4-inch hex key or hex bit driver. Ensure the mating threads are clean and free of debris before fastening. Do not over-torque alloy steel cap screws in tapped aluminum or cast-iron housings, as thread damage can result. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific assembly.
