Value Collection 2-H-87C-500 Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION 2-H-87C-500 is a 7/8-9 hex head cap screw measuring 5 inches in length under the head, manufactured from Grade 316 stainless steel with no finish coating applied. The partially threaded shank provides a bearing surface along the unthreaded portion, making it suited for clamping applications where shank engagement with a clearance hole is required. Grade 316 stainless steel offers superior corrosion resistance compared to Grade 304, particularly in chloride-rich and marine environments. This fastener is sized for standard inch-series tooling and is sold individually.

This cap screw is used across a wide range of commercial and industrial applications including HVAC equipment mounting, plumbing system fabrication, pool and aquatic equipment installation, and general structural assembly wherever corrosion resistance is a primary concern. The 7/8-9 thread form is a coarse UNC thread, compatible with standard hex nuts, lock nuts, and tapped holes of the same thread designation. It is a common choice in coastal, chemical-exposure, and wet-service environments where carbon steel fasteners would corrode prematurely.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in wet and chemical environments
• Partially threaded shank allows precision clamping and shear-load transfer through the unthreaded body
• 7/8-9 UNC coarse thread for compatibility with standard inch-series nuts and tapped holes
• Uncoated finish preserves base material properties without additional surface treatment
• 5-inch length under head accommodates thicker assemblies and flange stack-ups

Compatibility

Designed as a standard inch-series hex head cap screw for use with any 7/8-9 threaded nut, insert, or tapped hole per ASME B18.2.1 or equivalent fastener standards.

Installation Notes

Installation should be performed by a qualified tradesperson using a properly sized hex wrench or socket. Torque to the value specified in the applicable engineering or equipment documentation for the joint material and lubrication condition. Stainless steel fasteners are susceptible to galling during installation; apply an appropriate anti-seize compound to the threads before assembly. Never mix stainless and carbon steel fasteners in the same joint without evaluating galvanic corrosion risk.
