Value Collection R92412912 Hex Head Cap Screw 7/8-9 X 8 in

Product Description

The VALUE COLLECTION R92412912 is a partially threaded hex head cap screw designed for use in demanding fastening applications where corrosion resistance is critical. Manufactured from Grade 316 stainless steel with an uncoated finish, this fastener measures 7/8-9 thread size by 8 inches in length under the head, conforming to the Unified National Coarse (UNC) thread standard. The partial threading allows for a smooth shank section that improves shear strength and maintains alignment in bolted assemblies. Weighing approximately 0.008 pounds, it is suited for precision mechanical, structural, or fluid-system installations where material integrity matters.

This hex head cap screw is used across a wide range of industrial and trade applications including HVAC structural mounting, plumbing equipment fastening, pool and water treatment equipment assemblies, and general mechanical work where exposure to moisture, chemicals, or corrosive environments is a concern. Grade 316 stainless steel provides superior resistance to chlorides and saline environments compared to Grade 304, making this fastener well-suited for coastal, marine, or chemical-process settings. It is installed using standard hex drive tooling and is sold individually.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in harsh or wet environments
• 7/8-9 UNC thread size conforms to standard Unified National Coarse specifications
• 8-inch length under head accommodates deep or thick-stack fastening applications
• Partially threaded shank provides improved shear strength and bolt alignment
• Uncoated finish maintains dimensional consistency and is compatible with stainless hardware

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for assemblies requiring 7/8-9 UNC partially threaded hex head cap screws in Grade 316 stainless steel.

Installation Notes

This fastener is typically installed by mechanical, HVAC, or plumbing technicians using a standard hex wrench or socket rated for the 7/8-inch head size. Always ensure mating threads and hardware are compatible with 316 stainless steel to prevent galvanic corrosion. Shut down or de-energize the relevant system before fastening structural or equipment-mounting hardware. Follow applicable mechanical codes and manufacturer specifications for proper clamp load in the assembly.
