Value Collection 40599 Fully Threaded Stud 1/2-13 4in Steel 25pk

Product Description

The VALUE COLLECTION 40599 is a fully threaded stud with a 1/2-13 UNC thread form and a 4-inch overall length. Made from B7 alloy steel with an uncoated finish, this stud meets ASTM A193 standards and carries a Thread Fit Class 7B designation. Fully threaded studs like this one provide a continuous grip surface along the entire shank, making them well suited for bolted connections that require double-nut or insert-threaded assembly. Plumbers, pipefitters, electricians, and mechanical contractors commonly use ASTM A193 B7 studs in high-strength structural, pressure flange, and equipment mounting applications.

This stud is appropriate for industrial, commercial, and trade applications where a high-strength, standardized threaded fastener is required. Typical use cases include pipe flange assemblies, equipment base plates, and structural connections where a through-bolt or insert-mount configuration is needed. The ASTM A193 specification is commonly called out in pressure piping and process equipment work governed by ASME and IFGC standards. Sold in a package quantity of 25, this stud is suited for contractors stocking hardware for ongoing or recurring fastener needs.

Compatibility

Designed as a standard ASTM A193 B7 fully threaded stud suitable for use in pipe flange, structural, and mechanical equipment fastening applications requiring a 1/2-13 UNC threaded fastener with a 4-inch overall length.

Installation Notes

Installation is typically performed by pipefitters, millwrights, or mechanical contractors depending on the application. Shut down and de-energize or depressurize the assembly before removing or installing fasteners in live systems. Use properly rated nuts and washers matched to the 1/2-13 thread and B7 material grade. Follow applicable torque sequences per job specifications or relevant ASME or ASTM guidelines for flange and structural connections.
