Value Collection R56000852 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R56000852 is a hex socket cap screw designed for fastening applications that demand corrosion resistance and reliable clamping strength. Machined from 316 stainless steel with a bright, uncoated finish, this screw measures 4 inches under the head and carries a 5/16-18 UNC thread form. The 1/4-inch hex drive allows engagement with standard hex keys and Allen-type drivers. It is suited for use in marine, chemical, food-service, and industrial environments where 316-grade material is specified for elevated chloride or chemical exposure. Trade professionals in mechanical, HVAC, and plumbing service routinely stock these for panel fastening, equipment mounting, and structural hardware replacement.

This screw fits general-purpose fastening tasks across residential and commercial applications where a 5/16-18 UNC thread pitch is required. The 4-inch under-head length accommodates thicker stack-ups, spacer assemblies, and bracketed connections. The 316 stainless steel grade is commonly called out in coastal installations, pool and spa equipment enclosures, and any setting where 304-grade fasteners have shown early surface corrosion. It is sold individually but subject to a minimum order quantity of 5 pieces per transaction.

Key Features

• 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• 5/16-18 UNC thread for broad compatibility with standard inch-series tapped holes
• 4-inch length under head accommodates thicker material stack-ups and spacer assemblies
• 1/4-inch hex socket drive engages standard Allen keys and hex-bit drivers
• Bright uncoated finish maintains dimensional accuracy and resists galling when properly lubricated

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any tapped or through-hole application requiring a 5/16-18 UNC thread and a 4-inch under-head length.

Installation Notes

Installation is performed with a 1/4-inch hex key or Allen-bit driver; confirm the receiving thread is clean and free of debris before driving. Apply an anti-seize compound when threading 316 stainless fasteners into stainless tapped holes to prevent galling. Torque to the value specified by the equipment manufacturer or applicable structural standard. De-energize and de-pressurize any assembly before removing or replacing structural fasteners.
