Value Collection B8MSTFE0875C450 Threaded Stud 7/8-9

Product Description

The VALUE COLLECTION B8MSTFE0875C450 is a fully threaded stud machined to a 7/8-9 UNC thread form with a 4.5-inch overall length. The stud is manufactured from 316 stainless steel and meets ASTM B8M specifications, making it appropriate for corrosive or high-moisture service environments. Thread fit is Class 2A, indicating a standard external thread tolerance suitable for general industrial fastener applications. The uncoated plain finish leaves the base metal exposed, which is typical for 316 stainless installations where galvanic compatibility or weld prep is a concern. Licensed tradespeople and maintenance mechanics install this type of stud in flanged connections, structural assemblies, and equipment mounting applications.

This fully threaded stud is used in industrial, commercial, and marine service environments where 316 stainless steel is specified for corrosion resistance. Typical applications include pipe flange bolting, pump and valve mounting, and structural connections subject to moisture, chemicals, or outdoor exposure. The B8M designation aligns with ASTM standards for austenitic stainless fasteners used in pressure equipment and piping systems. Sold individually, this stud suits replacement or low-volume maintenance work where exact material traceability to the B8M standard is required.

Key Features

• 7/8-9 UNC thread form, fully threaded across the entire 4.5-inch length
• 316 stainless steel construction meets ASTM B8M specification for corrosion-resistant fastener service
• Class 2A external thread fit for standard tolerance fastener assemblies
• Right-hand thread direction, uncoated plain finish
• Suitable for pressure piping, marine, and chemical-exposure environments

Compatibility

Designed as an OEM-style replacement or direct-use fastener for industrial assemblies requiring a 7/8-9 fully threaded stud in 316 stainless steel with ASTM B8M compliance.

Installation Notes

Installation is typically performed by licensed millwrights, pipefitters, or maintenance mechanics working to ASME or ASTM fastener standards. Ensure mating nuts and tapped holes are rated for 316 stainless and Class 2A thread engagement before installation. Do not mix stainless fasteners with dissimilar metals in wet environments without verifying galvanic compatibility. Apply an anti-seize compound rated for stainless steel threads to prevent galling during assembly.
