Value Collection R57001046 Hex Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION R57001046 is a hex socket cap screw in 5/16-24 UNF thread with a 7/8-inch length under head. It is driven by a 1/4-inch hex key and manufactured from 18-8 stainless steel with a bright uncoated finish. This fastener is suited for general mechanical assembly, structural connections, and equipment maintenance tasks where corrosion resistance and thread integrity are required. Machinists, maintenance technicians, and tradespeople working on pumps, equipment enclosures, and similar assemblies regularly specify this type of cap screw for its clean seating and precise thread engagement.

This screw is appropriate for applications in HVAC equipment, plumbing fixtures, pool and pump assemblies, and light structural fabrication. The 5/16-24 UNF fine thread offers tighter thread engagement than coarse-thread equivalents, making it well suited for thin-material assemblies or installations where vibration resistance is a factor. The 18-8 stainless steel construction provides solid resistance to moisture, mild chemicals, and general atmospheric corrosion in both indoor and outdoor environments.

Key Features

• 5/16-24 UNF fine thread for increased vibration resistance and tighter engagement
• 7/8-inch length under head for consistent clamp load in standard-depth applications
• 1/4-inch hex drive for use with standard hex keys and socket drivers
• 18-8 stainless steel construction for corrosion resistance in wet or outdoor environments
• Bright uncoated finish with no added plating or treatment

Compatibility

Designed as a standard 5/16-24 UNF hex socket cap screw suitable for use in any assembly or equipment requiring this thread size and length specification.

Installation Notes

Install using a calibrated 1/4-inch hex key or T-handle driver to avoid rounding the socket drive. Ensure mating threads are clean and free of debris before installation. De-energize or shut down any equipment before fastener service. Avoid mixing stainless steel fasteners with dissimilar metals in high-galvanic environments without appropriate isolation.
