Value Collection R82230434 Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION R82230434 is a 5/16-18 hex head cap screw manufactured from 18-8 stainless steel with no coating applied. It features a 2-1/4-inch length under head and a Unified National Coarse (UNC) thread form. The 18-8 stainless steel construction provides solid corrosion resistance in general industrial and mechanical applications. This fastener is suited for use by maintenance technicians, millwrights, HVAC installers, plumbers, and electricians who need a reliable, corrosion-resistant threaded fastener for structural or equipment-mounting work.

This screw is appropriate for indoor and outdoor installations where moisture exposure is a concern and where a standard hex drive tool can be used. It is commonly used in equipment panels, framing brackets, pipe supports, and mechanical assemblies across residential and light commercial applications. The UNC thread pattern makes it compatible with the vast majority of standard tapped holes and hex nuts in inch-measurement applications.

Key Features

• 18-8 stainless steel material provides corrosion resistance without a coating requirement
• 5/16-18 UNC thread for broad compatibility with standard inch-system tapped holes and nuts
• 2-1/4-inch length under head suits medium-depth fastening applications
• Uncoated finish eliminates coating thickness variation for consistent thread fit
• Meets multiple MS military standards for dimensional and material compliance

Installation Notes

Install using a standard hex wrench or socket driver sized for a 5/16-18 fastener. De-energize or depressurize any equipment before replacing or installing fasteners in live assemblies. When installing stainless steel fasteners into stainless tapped holes, apply an anti-seize compound to the threads to prevent galling. Follow applicable mechanical and structural codes for torque and thread engagement requirements specific to the assembly.
