Value Collection 40597 Fully Threaded Stud 1/2-13 3 in Steel

Product Description

The VALUE COLLECTION 40597 is a fully threaded stud with a 1/2-13 UNC thread form and an overall length of 3 inches. Manufactured from steel to ASTM A193 material grade B7 standards, this stud delivers reliable tensile strength for demanding fastening applications. The uncoated finish is suitable for use where additional coating or plating will be applied in the field or where bare steel is acceptable. Thread fit class 7B ensures consistent engagement with standard 1/2-13 nuts and tapped holes. This type of fastener is commonly installed by millwrights, pipefitters, structural ironworkers, and mechanical contractors working in industrial and commercial settings.

Fully threaded studs in this size range are widely used in structural connections, pipe flange assemblies, equipment mounting, and general mechanical fastening where a bolt head would interfere with the installation. The 1/2-13 thread size is a standard coarse-thread designation that mates with readily available hex nuts, heavy hex nuts, and coupling nuts. The 3-inch overall length accommodates typical through-bolt and double-nut configurations in moderate-thickness material stackups. These studs are stocked for use in both new construction and maintenance-and-repair scenarios.

Key Features

• 1/2-13 UNC coarse thread runs the full 3-inch length for maximum engagement flexibility
• Material grade B7 alloy steel meets ASTM A193 specification for elevated-temperature and high-strength service
• Uncoated finish allows field application of zinc plating, hot-dip galvanizing, or protective coatings as required
• Thread fit class 7B provides a controlled interference fit suitable for prevailing-torque applications
• Fully threaded design eliminates a grip zone, allowing nut positioning anywhere along the stud length

Compatibility

Designed as a standard 1/2-13 fully threaded stud for use with compatible 1/2-13 hex nuts, heavy hex nuts, and coupling nuts in general industrial, mechanical, and structural fastening applications.

Installation Notes

Installation is typically performed by millwrights, pipefitters, or mechanical contractors using standard hand tools and torque wrenches. Always verify that mating tapped holes or nuts are clean and free of debris before threading the stud to full engagement. Follow applicable torque values from ASME or ASTM guidelines for grade B7 fasteners as referenced in the project specification. Never reuse studs that show visible thread deformation, corrosion pitting, or evidence of over-torquing.
