Value Collection 204123 Hex Head Cap Screw 1/4-20 316 Ss

Product Description

The VALUE COLLECTION 204123 is a 1/4-20 hex head cap screw machined from Grade 316 stainless steel. It measures 1-1/2 inches under the head with a 7/16-inch hex drive and follows the Unified National Coarse (UNC) thread standard. Grade 316 stainless offers higher corrosion resistance than 304, making it suitable for wet, chemical, or marine environments. This fastener is sized for standard 1/4-20 tapped holes and is used by mechanical contractors, plumbers, HVAC techs, and electricians wherever a corrosion-resistant threaded fastener is required in structural or equipment-mounting applications.

This cap screw is suited for use in corrosive or high-moisture environments such as pool equipment enclosures, HVAC condensing unit frames, plumbing fixture mounting, and electrical panel or enclosure assembly. The UNC thread form is the most common inch-series thread standard in North American trade applications, ensuring broad compatibility with standard tapped holes and nuts. It is sold individually with a minimum order quantity of 100 pieces.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• 1/4-20 UNC thread for compatibility with standard North American tapped holes and hardware
• 1-1/2 inches length under head for typical through-and-tapped fastening applications
• 7/16-inch hex drive accommodates standard wrenches and sockets
• Inch system of measurement — direct replacement for standard 1/4-20 hardware

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw for use in any application requiring Grade 316 stainless steel fasteners in an inch-series thread size.

Installation Notes

Install using a 7/16-inch open-end wrench, box wrench, or socket. De-energize or shut down any equipment before replacing fasteners on live assemblies. When fastening into stainless steel tapped holes, apply an anti-galling compound to prevent thread seizure, as 316 stainless is susceptible to galling under torque. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque requirements.
