Value Collection 207891 Hex Head Cap Screw 7/8-9 X 2 in 18-8 Ss

Product Description

The VALUE COLLECTION 207891 is a 7/8-9 hex head cap screw designed for general fastening applications in corrosion-resistant assemblies. Manufactured from 18-8 stainless steel, this screw provides reliable performance in environments where moisture, chemicals, or oxidation are a concern. The fastener measures 2 inches in length under the head and features a 1-5/16 inch hex drive. The Unified National Coarse thread form ensures broad compatibility with standard tapped holes and hardware. Installation requires a standard hex wrench or socket. This screw is sold individually and is well-suited for trade professionals needing a single replacement or low-quantity fastening solution.

This hex head cap screw is appropriate for use in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure hardware, and general mechanical applications where a corrosion-resistant fastener is required. The 18-8 stainless steel construction makes it a practical choice for both indoor and outdoor installations, including light marine-adjacent environments. It is commonly installed by HVAC technicians, plumbers, electricians, and mechanical contractors during equipment installation or field repair.

Key Features

• 18-8 stainless steel construction for corrosion and oxidation resistance
• 7/8-9 UNC thread for compatibility with standard inch-system tapped holes
• 2 inches length under head for adequate grip in typical structural and equipment fastening
• 1-5/16 inch hex drive for use with standard wrenches and sockets
• Sold as a single unit, eliminating the need to purchase in bulk

Compatibility

Designed as a standard inch-series hex head cap screw suitable for use in any application requiring a 7/8-9 UNC thread fastener in 18-8 stainless steel.

Installation Notes

Installation is performed by hand-threading the fastener into a pre-tapped or nut-bearing hole, then tightening with a properly sized hex wrench or socket. Always verify thread engagement before applying torque to avoid cross-threading. Ensure mating hardware is compatible with stainless steel to prevent galling — the use of anti-seize compound on the threads is a common field practice. Follow applicable mechanical codes and equipment manufacturer guidelines for fastener torque and installation requirements.
