Value Collection 31-S-25C-800 Hex Socket Cap Screw

Product Description

The VALUE COLLECTION 31-S-25C-800 is a hex socket cap screw designed for threaded fastening applications requiring corrosion resistance and precise torque engagement. It features a 1/4-20 UNC thread size and an 8-inch length under the head, making it suitable for deep-reach fastening tasks. The 3/16-inch internal hex drive accepts a standard hex key or Allen wrench for installation. Constructed from 18-8 stainless steel with a bright, uncoated finish, this fastener delivers solid strength in environments where oxidation resistance matters. Machinists, maintenance technicians, and fabricators use this type of hardware in equipment assembly and structural fastening.

This screw is appropriate for use in light industrial, commercial, and mechanical assembly applications where a 1/4-20 UNC thread pattern is specified. The 8-inch length under head suits applications requiring extended thread engagement or through-fastening of thick materials. The 18-8 stainless steel construction makes it a practical choice in wet, food-service, or mildly corrosive environments. It is sold individually and suits both field repair and original equipment assembly work.

Key Features

• 1/4-20 UNC thread size for standard inch-series threaded holes
• 8-inch length under head for extended reach and deep-thread engagement
• 3/16-inch internal hex drive for positive torque transfer with a hex key
• 18-8 stainless steel construction for corrosion resistance in wet or humid conditions
• Bright, uncoated finish maintains dimensional tolerances and accepts further treatment if needed
• Sold as a single unit for exact-quantity purchasing

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in any application calling for that thread size, a 3/16-inch hex drive, and an 8-inch length under the head in stainless steel.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver; ensure the tool seats fully in the socket before applying torque to avoid rounding the drive. De-energize or lock out any equipment before fastening into live assemblies. In threaded metal applications, verify the receiving hole thread is clean and free of debris before driving the screw. Stainless fasteners can be prone to galling in stainless-to-stainless applications; use an appropriate anti-seize compound if specified for the application.
