Value Collection AB7STFE0625C300 Fully Threaded Stud

Product Description

The VALUE COLLECTION AB7STFE0625C300 is a fully threaded stud with a 5/8-11 UNC thread form and a 3-inch overall length. Made from Grade B7 alloy steel with an uncoated plain finish, this stud is fully threaded its entire length, meaning the thread runs continuously from end to end with no unthreaded shank. The right-hand thread and Class 2A fit tolerance make it suitable for standard nut and tapped-hole assemblies where a moderate clearance fit is required. At 0.22 pounds, it is a single-piece fastener used across a wide range of structural and mechanical bolted joint applications.

This fully threaded stud is used in industrial, mechanical, and construction assemblies where a stud bolt is preferred over a cap screw. Common applications include equipment mounting, pipe flange connections, structural bracketing, and anywhere a through-bolted or double-nut installation is required. The B7 Grade steel specification makes it appropriate for higher-strength applications, including pressure vessel and piping flange assemblies where ASTM A193 Grade B7 material is called out. Trade professionals including pipefitters, millwrights, and mechanical contractors regularly use this fastener type.

Key Features

• Fully threaded along entire 3-inch length — no unthreaded shank
• 5/8-11 UNC right-hand thread for compatibility with standard 5/8-inch nuts and tapped holes
• Class 2A thread fit tolerance for standard clearance nut assemblies
• Grade B7 alloy steel construction for higher tensile strength requirements
• Uncoated plain finish — suitable for use as-is or with field-applied coatings or thread lubricants
• UNSPSC Code 31161618 for procurement classification

Compatibility

Designed as an OEM-style replacement or direct-use fastener for assemblies specifying a 5/8-11 fully threaded stud in Grade B7 alloy steel with a Class 2A thread fit.

Installation Notes

Installation is typically performed by pipefitters, millwrights, or mechanical contractors using standard hand tools and torque wrenches. Always follow the applicable torque specifications provided by the equipment or flange manufacturer — do not substitute generic torque values for engineered joint requirements. When used in flange or pressure vessel assemblies, verify material compliance against the applicable code such as ASME B16.5 or ASME PCC-1 before installation. Apply thread lubricant or anti-seize compound per the joint specification to achieve accurate clamp load.
