Value Collection AB7STFE1000C775 Threaded Stud B7

Product Description

The VALUE COLLECTION AB7STFE1000C775 is a fully threaded stud designed for heavy-duty fastening applications in industrial, mechanical, and structural assemblies. Manufactured from Grade B7 alloy steel with an uncoated plain finish, this stud features a 1-8 unified coarse thread and measures 7.75 inches in overall length. The full-thread design provides maximum thread engagement along the entire shank, making it well suited for through-bolting and double-nut configurations. Thread fit is Class 2A, the standard external thread tolerance class for general-purpose fasteners. Right-hand thread direction follows conventional installation practice. Licensed mechanics, millwrights, pipefitters, and industrial maintenance technicians are the primary installers of this type of hardware.

This fully threaded stud is used in applications requiring a strong, consistent clamping load across flanged joints, structural connections, machinery mounts, and pressure vessel assemblies. The 1-8 coarse thread pitch is a common specification in heavy equipment and piping systems. Grade B7 material meets ASTM A193 mechanical requirements for high-strength fastener service, including elevated-temperature and pressure-rated applications common in petrochemical, HVAC mechanical rooms, and industrial plant maintenance environments.

Key Features

• Full-thread design along the entire 7.75-inch length for maximum engagement flexibility
• 1-8 unified coarse thread, right-hand direction, Class 2A fit for standard external thread tolerance
• Grade B7 alloy steel construction for high-strength and elevated-temperature service
• Uncoated plain finish suitable for use with standard nuts, washers, and locking hardware
• No flat ground on shank, maintaining full cylindrical profile throughout

Compatibility

Designed as a standard 1-8 fully threaded stud for use with 1-8 unified coarse thread nuts and tapped holes in industrial and mechanical assemblies. Verify thread class and material grade requirements against the specific application before installation.

Installation Notes

Installation of fully threaded studs is typically performed by licensed millwrights, pipefitters, or qualified mechanical maintenance technicians. Always de-energize, depressurize, and lock out the system before replacing or installing fasteners in pressurized or powered assemblies. Use a calibrated torque wrench and follow the applicable joint specification or engineering drawing for proper clamp load. Apply thread lubricant or anti-seize compound as specified by the joint design to achieve accurate torque-to-tension results.
