Value Collection R63003686 Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R63003686 is a hex socket cap screw designed for secure, high-torque fastening in applications where a low-profile head and internal hex drive are required. Threaded 5/16-18 UNC, this fastener measures 3/4 inches under the head and accepts a 1/4-inch hex key drive. Constructed from 316 stainless steel, it offers strong corrosion resistance in wet, marine, and chemical-exposure environments. This screw is a standard choice for mechanical assemblies, equipment mounting, and structural connections across HVAC, plumbing, electrical, and general trade applications.

This fastener suits residential and commercial trade applications where a socket-drive cap screw is preferred over hex-head styles. The 5/16-18 UNC thread is a common coarse-thread specification found in a wide range of equipment frames, brackets, panels, and enclosures. The 316 stainless steel construction makes it well suited for outdoor installations, humid mechanical rooms, poolside equipment, and any environment where mild-steel fasteners would corrode prematurely.

Key Features

• 5/16-18 UNC coarse thread for broad compatibility with standard tapped holes
• 3/4-inch length under head for shallow-to-medium depth fastening
• 1/4-inch internal hex drive for use with standard Allen keys and hex bit sockets
• 316 stainless steel construction provides superior corrosion resistance over 304 grade
• Low-profile socket cap head allows installation in space-constrained assemblies

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use in any application requiring this thread size and head style. Consult equipment documentation to confirm thread engagement depth and torque requirements before installation.

Installation Notes

Installation is performed using a 1/4-inch hex key or Allen-type bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before fastening near live components. Do not overtighten — follow the torque specifications listed in the equipment manufacturer's documentation for 5/16-18 fasteners.
