Value Collection B7S100C850 Fully Threaded Stud Grade B7

Product Description

The VALUE COLLECTION B7S100C850 is a fully threaded stud used for bolting and fastening applications in industrial, mechanical, and structural assemblies. Machined from Grade B7 alloy steel in an uncoated finish, this stud measures 8.5 inches in overall length with a 1-8 thread size and a Class 2A thread fit. The 1-8 designation refers to a 1-inch nominal diameter with 8 threads per inch (UNC series). Grade B7 material meets the strength and hardness requirements commonly specified for high-temperature and high-pressure bolting, making it a standard choice in piping flanges, pressure vessels, and heavy equipment frames.

This stud is suited for use in industrial maintenance, plant facilities, structural fabrication, and mechanical assembly where a strong, through-threaded fastener is required. The fully threaded length of 8.5 inches allows nuts to be positioned anywhere along the stud, providing flexibility in clamping length and stack height. It is commonly installed by millwrights, pipefitters, and maintenance mechanics working on flanged connections, machinery bases, and equipment mounting applications.

Key Features

• Grade B7 alloy steel construction for high-strength bolting applications
• Fully threaded along the entire 8.5-inch length for maximum clamping flexibility
• 1-8 UNC thread size with Class 2A thread fit tolerance
• Uncoated finish suitable for use with standard nuts and washers
• Single-piece packaging with a minimum order quantity of 1

Compatibility

Designed as a general-purpose fully threaded stud for use with 1-8 UNC nuts in industrial, mechanical, and structural bolting applications requiring Grade B7 alloy steel fasteners.

Installation Notes

Installation should be performed by a qualified millwright, pipefitter, or mechanical technician. De-energize and depressurize any connected system before removing or installing studs in live assemblies. Use appropriately rated nuts and hardened washers that match the 1-8 thread specification and Grade B7 material class. Follow applicable torque sequences and fastener specifications as defined by the equipment manufacturer or applicable codes such as ASME PCC-1 for pressure boundary bolted joints.
