Value Collection B8MSTFE0500C550 Threaded Stud 1/2-13

Product Description

The VALUE COLLECTION B8MSTFE0500C550 is a fully threaded stud machined to 1/2-13 UNC thread form with an overall length of 5.5 inches. Manufactured from 316 stainless steel with an uncoated plain finish, this stud meets ASTM B8M standards and is classified to Thread Fit Class 2A with right-hand thread direction. Fully threaded along its entire 5.5-inch length, it provides maximum fastening flexibility in corrosive or high-moisture environments. Licensed plumbers, pipefitters, and maintenance technicians working in marine, chemical, or sanitary applications will find this stud suited to demanding service conditions where carbon steel fasteners are not appropriate.

This stud is suited for use in piping assemblies, pump mounting, flange connections, and structural fastening applications where 316 stainless steel is specified for corrosion resistance. It is commonly installed in commercial plumbing, HVAC equipment mounting, and industrial process piping. The 1/2-13 thread size and 5.5-inch length make it a practical choice for through-bolt applications requiring a standard coarse-thread fastener with full thread engagement across the entire shank.

Key Features

• Fully threaded 5.5-inch length allows flexible nut positioning anywhere along the shank
• 316 stainless steel construction resists corrosion in wet, marine, and chemical environments
• 1/2-13 UNC coarse thread, right-hand direction, Class 2A fit for standard tolerance applications
• Meets ASTM B8M standards for austenitic stainless steel bolting
• Uncoated plain finish — no coating to interfere with thread engagement or torque values

Compatibility

Designed as a standard 1/2-13 UNC fully threaded stud for use with any 1/2-13 compatible nut, coupling, or tapped hole requiring a Class 2A thread fit in stainless steel.

Installation Notes

Installation is typically performed by pipefitters, plumbers, or maintenance mechanics using standard open-end or box wrenches and appropriate 1/2-13 nuts. De-energize or shut down any connected system before replacing or installing fasteners in pressurized assemblies. Apply an appropriate anti-seize compound to stainless threads to prevent galling during installation. Follow applicable ASME, ASTM, or facility torque specifications for the joint design — do not overtorque stainless studs as they are susceptible to galling and thread damage.
