Value Collection B7S112C550 Fully Threaded Stud

Product Description

The VALUE COLLECTION B7S112C550 is a fully threaded stud machined from alloy steel to ASTM A193 Grade B7 specifications. Fully threaded along its entire 5.5-inch length, it carries a 1-1/8-8 UNC thread form with a Class 2A external thread fit — the standard tolerance for general fastener applications. The uncoated steel finish is suitable for use in dry or controlled environments. Grade B7 alloy steel delivers high tensile strength, making this stud appropriate for structural bolting, pressure vessel assemblies, flange connections, and mechanical clamping applications where load capacity and thread integrity matter.

This stud is used in industrial, mechanical, and trade applications requiring a strong, reliable threaded fastener. Typical installations include pipe flange bolting in plumbing and HVAC mechanical rooms, equipment mounting, and structural steel connections. Its fully threaded design provides maximum engagement flexibility, allowing nuts to be positioned anywhere along the length. It is commonly installed by pipefitters, millwrights, and mechanical contractors working to ASME and ANSI bolting standards.

Key Features

• Fully threaded along entire 5.5-inch overall length — no shoulder or reduced shank
• 1-1/8-8 UNC thread form for coarse-pitch heavy-duty bolting
• Class 2A thread fit — standard tolerance for industrial fastener applications
• ASTM A193 Grade B7 alloy steel for high tensile strength
• Uncoated finish — suitable for dry and controlled-environment installs

Compatibility

Designed as a general-purpose fully threaded stud for use with standard 1-1/8-8 UNC heavy hex nuts and washers in mechanical, structural, and piping flange assemblies.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or mechanical contractor familiar with applicable torque and bolting standards. Ensure mating threaded components carry a compatible 1-1/8-8 UNC internal thread and matching Class 2A or 2B tolerance. Inspect threads for damage before assembly. Follow ASME PCC-1 or applicable bolting procedures for flange joint applications, and apply thread lubricant or anti-seize only as specified by the joint design engineer.
