Value Collection 92039 Hex Socket Cap Screw 5/16-18 Unc

Product Description

The VALUE COLLECTION 92039 is a hex socket cap screw designed for secure, high-torque fastening in mechanical, plumbing, and light industrial assemblies. It features a 5/16-18 UNC thread size and a 1/2-inch length under head, driven by a 1/4-inch hex key. Constructed from 18-8 stainless steel, it offers good corrosion resistance in damp or mildly caustic environments. This screw is a standard choice where a clean, flush-driven fastener is needed and wrenching clearance is limited. Sold in multiples of 25.

This cap screw is suited for residential and light commercial applications where a socket-driven fastener is required in tight spaces. Common installation scenarios include equipment panels, pipe hangers, brackets, junction boxes, and mechanical assembly work across HVAC, plumbing, and electrical trades. The 18-8 stainless steel construction makes it appropriate for indoor and outdoor service environments where mild corrosion resistance is a factor.

Key Features

• 5/16-18 UNC thread — standard coarse thread for broad hardware compatibility
• 1/2-inch length under head — compact profile for shallow fastening applications
• 1/4-inch hex drive — compatible with standard hex keys and socket sets
• 18-8 stainless steel construction — resists rust and corrosion in wet or humid conditions
• Minimum order quantity of 25 — suited for service stock and batch fastener replenishment

Compatibility

Designed as a standard 5/16-18 UNC hex socket cap screw for use wherever a 1/4-inch hex drive, 1/2-inch under-head fastener of this thread size is specified.

Installation Notes

Installation is performed with a 1/4-inch hex key or Allen-head socket driver. Torque to the specification called out in the equipment or assembly documentation — do not exceed rated values for 18-8 stainless hardware, as this grade is susceptible to galling under excessive torque. De-energize and lock out any equipment before accessing fastened panels or components. Apply a suitable anti-gall lubricant when threading into stainless or aluminum tapped holes.
