Value Collection 204288 Hex Head Cap Screw 5/8-11 X 3 in

Product Description

The VALUE COLLECTION 204288 is a 5/8-11 hex head cap screw with a 3-inch length under head, manufactured from Grade 316 stainless steel. The 316 alloy provides superior corrosion resistance compared to standard 304 stainless, making it well suited for wet, chemical, or marine environments. The hex drive measures 15/16 inches across the flats. Thread standard is UNC (Unified National Coarse), and the fastener is dimensioned in the inch measurement system. This screw is typically installed by maintenance technicians, pipefitters, plumbers, and general industrial trades working on equipment assemblies, brackets, flanges, and structural connections.

This fastener is appropriate for use in residential and commercial mechanical applications where corrosion resistance and material compatibility are required. Common install scenarios include plumbing equipment supports, HVAC equipment mounts, pool and spa mechanical assemblies, and general industrial or marine hardware connections. The UNC thread form is widely compatible with standard tapped holes and hex nuts in 5/8-11 sizing.

Key Features

• Grade 316 stainless steel construction for elevated corrosion and chemical resistance
• 5/8-11 UNC thread for broad compatibility with standard inch-system tapped holes and nuts
• 3-inch length under head suits medium-depth fastening applications
• 15/16-inch hex drive fits standard SAE hex sockets and wrenches
• Inch measurement system dimensioning for use with standard American fastener tooling

Compatibility

Designed as a standard 5/8-11 UNC hex head cap screw for use in any application requiring a 3-inch Grade 316 stainless steel fastener in the inch measurement system.

Installation Notes

Installation requires a 15/16-inch hex socket or open-end wrench. Ensure mating threads are clean and free of debris before driving the fastener. When installing stainless steel fasteners, apply an anti-seize compound to the threads to prevent galling, which is a common issue with stainless-to-stainless assemblies. Follow applicable mechanical codes and equipment manufacturer torque guidelines for the specific joint being assembled.
