Value Collection B8MSTFE0500C525 Fully Threaded Stud

Product Description

The VALUE COLLECTION B8MSTFE0500C525 is a fully threaded stud in 1/2-13 UNC thread size with an overall length of 5.25 inches. Manufactured from 316 stainless steel with an uncoated plain finish, this stud meets ASTM B8M standards and carries a Class 2A thread fit. Fully threaded along its entire length, it provides maximum engagement flexibility for nuts, flanges, and threaded assemblies. The 316 alloy grade delivers strong corrosion resistance, making it well suited for wet, chemical, or marine environments. Installers and maintenance mechanics rely on this type of fastener where standard carbon steel would be inadequate due to exposure conditions.

This fully threaded stud is used in mechanical, plumbing, HVAC, and industrial piping assemblies where a continuous thread length is required. Common applications include flange bolting, equipment mounting, pump connections, and pressure-vessel fastening in corrosive or high-moisture environments. The 1/2-13 UNC thread pattern is one of the most widely used coarse-thread sizes in trade and industrial work, compatible with standard 1/2-13 hex nuts and flanged hardware. The right-hand thread direction follows standard convention for the vast majority of fastening applications.

Key Features

• Fully threaded along the entire 5.25-inch overall length for maximum installation flexibility
• 316 stainless steel construction provides superior corrosion resistance in wet, chemical, and marine service
• 1/2-13 UNC coarse-thread profile — one of the most common trade fastener sizes
• Class 2A thread fit meets standard tolerance requirements for general mechanical assemblies
• Meets ASTM B8M standards for austenitic stainless steel bolting
• Uncoated plain finish — no plating that could introduce dimensional variation or galvanic concerns

Compatibility

Designed for use with standard 1/2-13 UNC hex nuts, coupling nuts, and threaded flanges in mechanical, plumbing, and industrial fastening applications where 316 stainless steel material and ASTM B8M compliance are required.

Installation Notes

Installation is typically performed by millwrights, pipefitters, plumbers, or maintenance mechanics using standard 1/2-inch drive tooling and appropriately rated nuts. Follow applicable mechanical and piping codes for torque sequencing on flanged connections — do not rely on feel alone when fastening pressure-rated assemblies. Inspect threads for damage before installation and apply an anti-seize compound compatible with stainless steel to prevent galling, which is a common failure mode with austenitic alloys. Never use impact tools at full torque on stainless fasteners without proper anti-seize treatment.
