Value Collection 204134 Hex Cap Screw 1/4-20 2.5in 316 Ss

Product Description

The VALUE COLLECTION 204134 is a hex head cap screw designed for general fastening applications requiring corrosion resistance. Sized at 1/4-20 with a 2.5-inch length under head, this fastener is manufactured from Grade 316 stainless steel, which provides strong resistance to chlorides, chemicals, and marine environments. The 7/16-inch hex drive allows standard wrench or socket installation. It follows Unified National Coarse (UNC) thread standards, making it compatible with the widest range of standard tapped holes and nuts. Plumbers, HVAC technicians, and industrial maintenance trades commonly specify 316 stainless fasteners where moisture or chemical exposure is a regular service condition.

This screw is well suited for use in wet, coastal, or chemically active environments such as pool and spa equipment enclosures, HVAC condensate pan assemblies, plumbing fixture mounting, and outdoor electrical panel applications. The UNC thread form and inch-system dimensions make it straightforward to source matching hardware on any standard job site. It is sold individually but carries a minimum order quantity of 25 units, making it practical for stocking service vehicles or shop inventory.

Key Features

• Grade 316 stainless steel construction resists chlorides, salt spray, and mild chemical exposure
• 1/4-20 UNC thread form fits standard inch-system tapped holes and nuts
• 2.5-inch length under head suits deeper fastening applications where longer engagement is needed
• 7/16-inch hex head accepts standard wrenches and sockets
• Inch measurement system for compatibility with domestic trade hardware

Compatibility

Designed as a standard inch-system hex head cap screw for use with any 1/4-20 UNC tapped hole, nut, or threaded insert requiring a Grade 316 stainless steel fastener.

Installation Notes

Installation is performed by hand-starting the screw into a clean, properly tapped 1/4-20 UNC hole before applying a wrench or socket to the 7/16-inch hex head. Do not use impact tools at full torque on stainless steel fasteners, as galling can occur and seize the thread permanently. Apply an anti-seize compound rated for stainless steel when installing into stainless or aluminum tapped holes. Follow applicable mechanical or building codes for fastener selection in structural or pressure-bearing applications.
