Value Collection 207829 Hex Head Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 207829 is a 5/16-18 hex head cap screw with a 1-1/4 inch length under head, manufactured from 18-8 stainless steel. This fastener features a Unified National Coarse (UNC) thread standard and a 1/2 inch hex drive size. The 18-8 stainless steel construction provides solid corrosion resistance in wet, outdoor, and chemically active environments. It is a standard inch-system fastener used across mechanical, HVAC, plumbing, electrical, and general fabrication applications by trade professionals and maintenance technicians alike.

This cap screw is suited for residential and commercial maintenance, equipment assembly, panel mounting, and structural fastening tasks where corrosion resistance is a priority. The UNC thread form is the most common inch-system thread standard, making this screw compatible with a wide range of tapped holes, nuts, and threaded inserts found in trade equipment and structural components. It is typically installed by hand-starting and driven with a standard hex wrench or socket.

Key Features

• 18-8 stainless steel construction for corrosion resistance in wet and outdoor environments
• 5/16-18 UNC thread for compatibility with the most common inch-system threaded fittings
• 1-1/4 inch length under head for standard-depth fastening applications
• 1/2 inch hex drive size compatible with standard sockets and wrenches
• Inch measurement system for use with standard SAE tooling and hardware

Compatibility

Designed as a standard 5/16-18 UNC inch-system hex head cap screw suitable for general mechanical and trade fastening applications where an 18-8 stainless steel fastener is specified.

Installation Notes

This fastener is installed by mechanical, HVAC, plumbing, and electrical tradespeople using a standard 1/2 inch hex socket or wrench. Ensure the mating thread is clean and free of debris before installation. Do not exceed the torque capacity of the stainless steel material, as 18-8 stainless is susceptible to galling if over-torqued or driven without lubrication. Apply an anti-seize compound when fastening into dissimilar metals or in high-moisture environments.
