Dan-loc Bolt Gasket 000-04-035 Fully Threaded Stud

Product Description

The DAN-LOC BOLT GASKET 000-04-035 is a fully threaded stud machined from Grade B7 alloy steel with a 1/2-13 UNC thread form and an overall length of 3.5 inches. It carries an uncoated plain finish, leaving the alloy steel exposed for applications where a coating would interfere with fit or where additional plating will be applied on-site. Fully threaded studs like this one are used in bolted flange assemblies, pipe connections, pressure vessels, and structural fastening wherever a stud must engage threaded material on both ends without a shoulder or blank shank section.

This stud is suited for industrial, mechanical, and plumbing trade applications that require a reliable high-strength fastener. Grade B7 alloy steel is a common specification in pressure piping and flange work per ASTM A193 standards, making this stud appropriate for use in moderate- to high-temperature and high-pressure systems. It is typically installed by pipefitters, plumbers, and millwrights working on flanged connections in commercial or industrial settings where dimensional consistency and material grade are specified by the engineer of record.

Key Features

• 1/2-13 UNC thread form runs the full 3.5-inch length - no blank shank section
• Grade B7 alloy steel construction meets common ASTM A193 material specifications for pressure and temperature applications
• Uncoated plain finish maintains dimensional tolerances and allows field coating or plating as required
• Compact 3.5-inch overall length suits tight flange and manifold bolt patterns
• Sold as a single piece - order exact quantities needed without minimum pack overruns

Compatibility

Designed as a standard 1/2-13 UNC fully threaded stud for use in flanged pipe assemblies, pressure vessels, and mechanical fastening applications that specify Grade B7 alloy steel fasteners.

Installation Notes

Installation should be performed by a qualified pipefitter, plumber, or mechanical contractor following applicable codes such as ASME B31.3 or ASME B16.5 for flanged connections. Shut down and depressurize the system completely before disassembling any flanged joint. Use a calibrated torque wrench and follow the flange manufacturer or engineering specifications for torque pattern and target values. Do not mix fastener material grades within a single flange bolt circle.
