Macomb Group Approved 062375B8MS 316SS Stud 5/8-11 Unc

Product Description

The MACOMB GROUP APPROVED 062375B8MS is a fully threaded stud machined from 316 stainless steel to Grade B8M specifications under ASTM A193. It measures 5/8 inch in diameter with a 5/8-11 UNC thread pattern and an overall length of 3-3/4 inches. Grade B8M material delivers a minimum tensile strength of 75 KSI and a minimum yield strength of 30 KSI, making it well suited for moderate-load fastening applications where corrosion resistance is a primary concern. Licensed tradespeople and industrial maintenance professionals use this stud in bolted flange assemblies, pressure vessel connections, and piping systems requiring reliable stainless fasteners.

This stud is intended for use in environments where exposure to moisture, chemicals, or corrosive media rules out carbon steel hardware. Typical applications include process piping flanges, pump and valve assemblies, and marine or coastal mechanical installations. The 316 stainless steel alloy provides enhanced chloride resistance compared to 304 SS, making it a common choice in chemical processing, food-service equipment, and coastal HVAC or plumbing infrastructure. Installers working under ASME or ANSI flange standards will find the ASTM A193 B8M designation meets common material requirements for those specifications.

Key Features

• 316 stainless steel construction provides superior corrosion and chloride resistance
• Grade B8M per ASTM A193 - a recognized material standard for pressure and high-temperature fastener applications
• 5/8-11 UNC thread form for broad compatibility with standard hex nuts and flange hardware
• 75 KSI minimum tensile strength and 30 KSI minimum yield strength
• 3-3/4 inch length suits typical flange stud bolt configurations

Compatibility

Designed as an OEM-style replacement or maintenance stud for bolted flange assemblies, pressure vessel connections, and piping systems requiring ASTM A193 Grade B8M 316 stainless steel fasteners with a 5/8-11 UNC thread.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or mechanical contractor familiar with ASME bolted flange procedures. Disengage all system pressure and isolate the line before removing or replacing flange hardware. Use calibrated torque tooling and follow the applicable flange or equipment manufacturer torque sequence - do not rely on feel alone for pressure-boundary fasteners. Verify nut material compatibility with 316 SS studs to avoid galvanic or galling issues.
