Value Collection B8MSTFE0625C425 Fully Threaded Stud

Product Description

The VALUE COLLECTION B8MSTFE0625C425 is a fully threaded stud in 5/8-11 unified coarse thread, manufactured from 316 stainless steel to ASTM B8M standards. The stud measures 4.25 inches overall length with full thread engagement from end to end and carries a Class 2A thread fit, which is the standard external thread tolerance for general fastener applications. The uncoated plain finish leaves the base stainless steel alloy exposed for corrosion resistance in demanding environments. This fastener is installed by millwrights, pipefitters, plumbers, and mechanical contractors in applications where high corrosion resistance and material traceability are required.

The B8MSTFE0625C425 is suited for use in marine, chemical processing, food service, and industrial piping environments where 316 stainless steel is specified for its elevated chloride and corrosion resistance over standard 304 alloy. The fully threaded design allows full engagement into threaded inserts, flanges, or equipment housings, and accommodates standard hex nuts across the entire shank length. It is appropriate for both structural fastening and through-bolt configurations where the application demands stainless material to meet corrosion or sanitary codes.

Key Features

• 316 stainless steel construction meets ASTM B8M material standard for elevated corrosion resistance
• 5/8-11 unified coarse thread pitch with Class 2A external thread fit
• Fully threaded 4.25-inch length allows flexible engagement depth and nut positioning
• Right-hand thread direction for standard installation tooling
• Uncoated plain finish preserves base alloy properties without plating or coating

Compatibility

Designed as a direct-fit fully threaded stud for applications requiring 5/8-11 thread size and 316 stainless steel material conforming to ASTM B8M specification.

Installation Notes

Install using standard 5/8-11 hex nuts and appropriate torque wrenches; consult applicable ASME or project specifications for torque values. Ensure mating threaded holes or inserts are clean and free of debris before installation. Stainless steel fasteners are susceptible to galling during installation — apply an anti-seize compound rated for stainless hardware when assembling into stainless or aluminum mating threads. Follow applicable mechanical or piping codes for the specific installation environment.
