Value Collection B7S100C400 Fully Threaded Stud

Product Description

The VALUE COLLECTION B7S100C400 is a fully threaded stud designed for high-strength bolted connections in industrial, mechanical, and structural applications. Manufactured from B7 alloy steel in an uncoated finish, this stud carries a Class 2A thread fit, which is the standard external thread tolerance class for general-purpose fastener use. The stud measures 4 inches in overall length with a 1-8 UNC thread size running the full length, making it suitable for use with heavy hex nuts and thick flanged connections where continuous thread engagement is required. Weighing 0.75 pounds, it offers substantial material cross-section for load-bearing use. Licensed tradespeople and industrial maintenance technicians install this type of fastener in piping flanges, equipment mounts, and structural assemblies.

This fully threaded stud is suited for use in general industrial, HVAC mechanical room, plumbing infrastructure, and structural equipment mounting applications. The B7 material grade indicates medium-carbon alloy steel heat-treated to deliver high tensile strength, making it a common choice for pressure vessel flanges, pipe flanges, and heavy mechanical assemblies operating under elevated stress or temperature conditions. A licensed mechanic or pipefitter would typically install this stud in conjunction with compatible Grade 2H heavy hex nuts torqued to fastener-specification requirements.

Key Features

• Full-length 1-8 UNC threading allows maximum thread engagement and flexible nut positioning
• B7 alloy steel material grade provides high tensile strength for demanding load applications
• Class 2A thread fit meets standard external thread tolerance for broad nut compatibility
• Uncoated finish suitable for dry or controlled environments and field modification
• 4 inches overall length with consistent thread pitch end to end

Compatibility

Designed as an OEM-style replacement or standard-service fully threaded stud for industrial and mechanical applications requiring a 1-8 UNC thread and 4-inch overall length in B7 alloy steel.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or millwright familiar with ASME fastener torque specifications for the applicable joint. Always de-energize, depressurize, and isolate the system before removing or replacing studs in flange or equipment connections. Use a calibrated torque wrench and apply fastener lubricant only as specified by the joint design or applicable code. Inspect threads for damage before installation and replace any stud that shows galling, cross-threading, or corrosion.
