Value Collection B8MSTFE0500C275 Threaded Stud 1/2-13

Product Description

The VALUE COLLECTION B8MSTFE0500C275 is a fully threaded stud machined to ASTM B8M standards in 316 stainless steel with an uncoated plain finish. The stud runs 1/2-13 UNC thread along its entire 2.75-inch overall length, providing maximum engagement depth in both mating components. Thread fit is Class 2A, the standard external thread tolerance used in most fastener assemblies where normal fit and easy installation are required. Right-hand thread direction. 316 stainless provides corrosion resistance in wet, chemical, and marine environments. Mechanical and structural trade professionals select this grade when carbon steel or 18-8 stainless is insufficient for the service environment.

This fully threaded stud is suited for use in flanged connections, structural assemblies, equipment mounting, and piping applications where double-nut or through-bolt installation is required. The 316 stainless material grade makes it appropriate for chemical processing, marine, food-service, and outdoor infrastructure applications where chloride or corrosive media exposure is a concern. It is commonly installed by pipefitters, millwrights, and maintenance mechanics working on industrial or commercial equipment.

Key Features

• Full thread engagement along the entire 2.75-inch length for maximum holding strength
• 316 stainless steel construction provides superior resistance to chloride corrosion compared to 304 or 18-8 grades
• ASTM B8M standard compliance for use in pressure vessel and structural fastener applications
• 1/2-13 UNC thread size — one of the most common coarse-thread sizes in industrial fastener work
• Class 2A external thread fit for reliable engagement with standard Class 2B nuts and tapped holes
• Uncoated finish maintains dimensional accuracy and avoids coating interference in tight-tolerance assemblies

Compatibility

Designed as a standard 1/2-13 UNC fully threaded stud for use with Class 2B tapped holes or standard hex nuts conforming to ASTM B8M specifications.

Installation Notes

Installation is typically performed by a pipefitter, millwright, or maintenance mechanic using standard hand tools. Torque the stud using a double-nut method to avoid direct contact with the stud body. In pressure vessel or piping service, verify that fastener material grade meets the system design specification and applicable code requirements before installation. Do not mix stainless fastener grades in galvanic-sensitive assemblies without reviewing compatibility with the mating material.
