Value Collection R56000264 Hex Head Cap Screw 7/8-9

Product Description

The VALUE COLLECTION R56000264 is a fully threaded hex head cap screw designed for industrial and trade applications requiring corrosion resistance and structural integrity. Sized at 7/8-9 x 4 inches with a Unified National Coarse (UNC) thread standard, this fastener is manufactured from Grade 316 stainless steel and left uncoated, making it well suited for wet, chemical-exposure, or marine environments where standard carbon steel fasteners would corrode prematurely. Measurement is taken as length under head, providing consistent reference for flange and joint assembly work. Installation requires a standard hex wrench or socket set appropriate for the 7/8-inch head size.

This fastener is used across a broad range of mechanical, structural, and process-equipment applications. It is a common choice in HVAC equipment mounting, plumbing support systems, pump and pipe flange connections, pool and water treatment equipment, and general industrial fabrication. The fully threaded shank allows engagement along the entire bolt length, which is particularly useful in thin-material or through-bolt installations. Tradespeople in plumbing, mechanical contracting, and maintenance work will encounter this fastener in new construction and retrofit scenarios alike.

Key Features

• Grade 316 stainless steel construction provides superior resistance to chlorides, acids, and corrosive environments
• Fully threaded shank for maximum thread engagement across the entire 4-inch length
• 7/8-9 UNC thread form ensures compatibility with standard inch-system nuts and tapped holes
• Uncoated finish eliminates coating delamination concerns in submerged or chemical-wash applications
• Hex head drive style accepts standard sockets, wrenches, and impact tools

Compatibility

Designed for use with standard 7/8-9 UNC hex nuts, washers, and tapped components conforming to inch-series fastener specifications.

Installation Notes

Installation should be performed by qualified mechanical or maintenance tradespeople familiar with fastener torque requirements for the applicable joint and material. Always confirm thread engagement depth and mating nut grade before final assembly. In stainless steel fasteners, anti-seize compound is strongly recommended to prevent galling during installation and future removal. Follow applicable ASME, ANSI, or project-specific fastener standards for proper joint design.
