Value Collection B8MSTFE0500C325 Fully Threaded Stud

Product Description

The VALUE COLLECTION B8MSTFE0500C325 is a fully threaded stud machined from 316 stainless steel and supplied with a plain, uncoated finish. It carries a 1/2-13 UNC thread form with a Class 2A fit, a right-hand thread direction, and a 3.25-inch overall length that is fully threaded from end to end. The B8M designation indicates conformance to ASTM A193 alloy and austenitic stainless steel specifications. This fastener is suited for structural, pressure-boundary, and process-piping applications where corrosion resistance and tensile strength are the primary concerns. Installation is performed by pipefitters, millwrights, and maintenance mechanics.

This fully threaded stud is a standard choice in industrial and commercial applications involving flanged pipe connections, pressure vessel assemblies, heat exchangers, and structural bolting in corrosive environments. The 316 stainless steel material grade provides elevated resistance to chlorides and oxidizing media compared to 304-grade fasteners, making it appropriate for marine, chemical, and food-processing installations. The 1/2-13 thread size and 3.25-inch length are among the most common dimensions specified in ASME and ASTM B8M fastener standards.

Key Features

• Fully threaded 3.25-inch length — no plain shank, full engagement across the entire body
• 1/2-13 UNC thread with Class 2A fit for standard-tolerance mating nuts and flanges
• 316 stainless steel construction for superior chloride and corrosion resistance
• Right-hand thread direction, compatible with standard hex nuts and coupling nuts
• Plain, uncoated finish — no plating or coating that could affect dimensional tolerances
• Conforms to ASTM A193 B8M standard for high-temperature and corrosive-service bolting

Compatibility

Designed as an OEM-style and aftermarket replacement fastener for applications requiring ASTM A193 B8M fully threaded studs with a 1/2-13 thread and 3.25-inch overall length.

Installation Notes

Installation is typically performed by pipefitters, millwrights, or maintenance mechanics. Always de-energize, depressurize, and isolate the system before removing or installing fasteners in flanged or pressure-boundary assemblies. Apply an appropriate anti-seize compound to stainless steel threads before installation to prevent galling — this is standard practice for austenitic stainless fasteners. Torque to the value specified by the flange standard or equipment manufacturer, and verify alignment before final tightening.
