Value Collection R40691404 Hex Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION R40691404 is a hex socket cap screw designed for fastening applications that demand a compact drive profile and reliable corrosion resistance. This screw uses a 5/16-24 UNF thread, which is a fine-pitch unified thread commonly specified where vibration resistance or precise thread engagement is critical. The drive is a 1/4 inch internal hex socket, accepting a standard hex key or Allen-type driver. Fabricated from 18-8 stainless steel, this fastener provides good resistance to rust and oxidation in moderate environments. Licensed tradespeople and assembly technicians working in HVAC, plumbing, electrical, or general mechanical applications will encounter this fastener type on equipment panels, brackets, and structural hardware.

This screw is suited for applications requiring a fine-thread cap screw in stainless steel, including equipment enclosures, mechanical assemblies, and fixtures where a flush or low-profile fastening method is preferred. The 1/2 inch length under head accommodates thin material stacks and standard bracket thicknesses common in trade equipment. The fine 5/16-24 UNF thread pitch is commonly used in precision mechanical and industrial assemblies.

Key Features

• 5/16-24 UNF fine-thread profile for improved vibration resistance
• 1/4 inch hex socket drive compatible with standard hex keys and bit drivers
• 1/2 inch length under head for thin-material fastening applications
• 18-8 stainless steel construction for corrosion resistance in moderate environments
• UNSPSC Code 31161501 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring a 5/16-24 UNF hex socket cap screw in 18-8 stainless steel with a 1/2 inch length under head.

Installation Notes

Installation should be performed by a qualified technician familiar with torque requirements for stainless steel fasteners in the relevant application. Use the correct 1/4 inch hex key or driver bit to avoid rounding the socket. De-energize or shut down any equipment before accessing fastening points on live assemblies. Avoid mixing stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion.
