Value Collection 204283B Hex Head Cap Screw 5/8-11 2.5in 316SS

Product Description

The VALUE COLLECTION 204283B is a hex head cap screw designed for fastening applications that demand corrosion resistance and dimensional accuracy. Sized at 5/8-11 thread with a 2-1/2 inch length under head, this fastener is manufactured from Grade 316 stainless steel, which offers superior resistance to chlorides, acids, and marine environments compared to standard 304 stainless. The 15/16 inch hex drive accommodates standard wrenches and sockets. This screw follows Unified National Coarse (UNC) thread standards, ensuring compatibility with standard tapped holes and nuts in the same thread family. It is suited for trade professionals who need a reliable, corrosion-resistant fastener for structural or mechanical assemblies.

This fastener is commonly used in HVAC equipment mounting, plumbing system assembly, pool and spa equipment installation, and general mechanical applications where exposure to moisture, chemicals, or outdoor conditions is a concern. Grade 316 stainless is the preferred choice for coastal installations, chemical processing environments, and anywhere standard steel fasteners would corrode prematurely. Suitable for both new construction and maintenance or retrofit work across commercial and residential settings.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chloride resistance
• 5/8-11 UNC thread for compatibility with standard tapped holes and hardware
• 2-1/2 inch length under head for medium to heavy fastening depth requirements
• 15/16 inch hex drive fits standard wrenches and sockets
• Inch measurement system with UNC thread standard for broad compatibility

Compatibility

Designed as a standard UNC hex head cap screw compatible with any 5/8-11 tapped hole or matching nut in inch-measurement applications.

Installation Notes

This fastener is installed by licensed trades and maintenance technicians using a standard 15/16 inch wrench or socket. Always de-energize and isolate the equipment being serviced before accessing fastener locations on electrical or mechanical assemblies. Do not mix stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern. Apply a anti-seize compound rated for stainless fasteners when installing in high-heat or marine environments to prevent galling during future removal.
