Value Collection AB7STFE1000C525 Threaded Stud 1-8

Product Description

The VALUE COLLECTION AB7STFE1000C525 is a fully threaded stud used to create bolted connections in structural, mechanical, and industrial assemblies. It is manufactured from Grade B7 alloy steel with an uncoated plain finish and carries a Class 2A external thread fit, which is the standard tolerance class for general-purpose fasteners. The 1-8 thread designation indicates a 1-inch nominal diameter with 8 threads per inch (UNC series). Overall length is 5-1/4 inches, and the stud is threaded its entire length. Installers in industrial, HVAC structural, and piping applications commonly use this fastener where continuous thread engagement is required on both ends.

This fully threaded stud is suited for use in heavy mechanical assemblies, pipe flanges, equipment mounting, and structural framing where a standard hex bolt is not practical. The Grade B7 material designation indicates a medium-carbon alloy steel that is quenched and tempered, making it appropriate for higher-load applications. Right-hand thread direction is standard, so it mates with any standard right-hand 1-8 threaded nut or tapped hole. It is sold individually and is a fit for industrial maintenance, commercial construction, and mechanical contractor applications.

Key Features

• Fully threaded along the entire 5-1/4 inch length for maximum nut engagement flexibility
• Grade B7 alloy steel construction for elevated tensile and yield strength requirements
• 1-8 UNC thread form with Class 2A fit for compatibility with standard hardware
• Right-hand thread direction — mates with all standard 1-8 threaded fasteners
• Uncoated plain finish — suitable for use as-is or with field-applied coatings or lubricants
• UNSPSC Code 31161618 for procurement and catalog classification

Compatibility

Designed for use with any standard 1-8 UNC right-hand threaded nut, coupling nut, or tapped hole conforming to Class 2B internal thread tolerances. Typical fitment is in industrial and mechanical assemblies requiring a Grade B7 alloy steel fastener.

Installation Notes

Installation is performed by mechanical contractors, millwrights, pipefitters, or maintenance technicians using standard open-end, box, or socket wrenches sized for the mating nut. De-energize and depressurize any connected system before removing or installing studs in pressurized or live applications. Apply thread lubricant or anti-seize compound as required by the application to achieve accurate torque-to-clamp-load relationships. Follow applicable mechanical codes and equipment manufacturer torque specifications when determining final tightening values.
