Value Collection 203051 Hex Head Cap Screw 5/8-11 X 2 in

Product Description

The VALUE COLLECTION 203051 is a 5/8-11 UNC hex head cap screw measuring 2 inches under the head, manufactured from Grade 316 stainless steel. Grade 316 stainless offers superior corrosion resistance compared to Grade 304, making it a common choice in wet, chemical, or marine environments. The 15/16-inch hex drive accepts standard combination wrenches and sockets. This fastener is sold individually with a minimum order quantity of 25 pieces, suitable for procurement by maintenance technicians, pipefitters, plumbers, and mechanical contractors who need corrosion-resistant hardware for structural and equipment assembly applications.

This screw is appropriate for use in residential and commercial applications where moisture, chlorides, or mild chemical exposure is present. Typical install scenarios include pipe supports, HVAC equipment mounting, pump and valve assemblies, pool and spa mechanical rooms, and marine or coastal equipment installations. The UNC thread form is the standard coarse-thread series used throughout North American mechanical construction, making this fastener broadly compatible with standard tapped holes and hex nuts in that thread class.

Key Features

• Grade 316 stainless steel construction for enhanced corrosion resistance in wet and chemical environments
• 5/8-11 UNC thread form for compatibility with standard coarse-thread hardware
• 2-inch length under head for medium-depth fastening applications
• 15/16-inch hex drive accepts standard wrenches and sockets
• Inch measurement system, consistent with North American trade standards

Compatibility

Designed as a standard 5/8-11 UNC hex head cap screw compatible with any tapped hole, nut, or threaded insert conforming to the UNC coarse-thread standard in 5/8-inch diameter.

Installation Notes

Installation is performed by mechanical contractors, pipefitters, plumbers, or maintenance technicians using a standard combination wrench or socket set sized for a 15/16-inch hex. Ensure mating threads are clean and free of debris before installation. When fastening into dissimilar metals, consider galvanic compatibility to prevent accelerated corrosion at the joint. Follow applicable mechanical and structural codes for torque and fastener spacing requirements.
