Value Collection R63003842 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R63003842 is a hex socket cap screw designed for fastening applications that require corrosion-resistant hardware. Manufactured from 316 stainless steel, this screw features a 5/16-18 UNC thread size and a 2-inch length under head. The 1/4-inch hex drive allows engagement with standard Allen keys and hex bit drivers. Grade 316 stainless steel provides superior resistance to chlorides and harsh environments compared to 304 grade, making this fastener well suited for marine, chemical, and outdoor industrial applications. Licensed tradespeople and maintenance technicians rely on socket cap screws like this for secure, recessed fastening where a low-profile head is required.

This hex socket cap screw is appropriate for use in mechanical assemblies, equipment mounting, and structural fastening across residential and commercial service environments. The 5/16-18 UNC coarse thread pattern is compatible with standard tapped holes and hex nuts of the same specification. Its 316 stainless steel construction makes it a common choice in plumbing, pool equipment, and coastal or chemical-processing installations where fastener corrosion is a primary maintenance concern.

Key Features

• 316 stainless steel construction for high corrosion resistance in harsh or wet environments
• 5/16-18 UNC coarse thread for compatibility with standard tapped holes and nuts
• 2-inch length under head for secure engagement in deeper assemblies
• 1/4-inch hex drive accepts standard Allen keys and hex bit drivers
• Low-profile socket cap head allows recessed fastening in tight clearances

Compatibility

Designed as an OEM-style replacement or maintenance fastener for any application requiring a 5/16-18 UNC hex socket cap screw with a 2-inch length under head in 316 stainless steel.

Installation Notes

Installation is performed with a 1/4-inch hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before driving the screw. Do not overtighten stainless steel fasteners, as galling can occur — apply an anti-seize compound to the threads when working in high-moisture or dissimilar-metal environments. Follow applicable mechanical and structural codes for the specific assembly being fastened.
