Dan-loc Bolt Gasket 130-05-040 Fully Threaded Stud 5/8-11

Product Description

The DAN-LOC BOLT GASKET 130-05-040 is a fully threaded stud machined from Grade 316 stainless steel with an uncoated finish. It carries a 5/8-11 UNC thread form along its entire 4-inch overall length, delivering uniform grip and load distribution without a shoulder or partial shank. Grade 316 stainless provides elevated resistance to chloride corrosion and oxidation, making it a dependable fastener in demanding environments. This stud meets ASTM B8M standards and is sold individually. It is installed by pipefitters, millwrights, maintenance mechanics, and industrial tradespeople working in corrosion-critical assemblies.

This fully threaded stud is suited for use in flanged pipe connections, pressure vessel assemblies, pump housings, and structural bracketing where corrosion resistance is a primary requirement. The 5/8-11 thread size and 4-inch length are common in medium-duty industrial and marine applications. Its full-thread design allows it to be cut to a shorter working length in the field, offering installation flexibility in tight clearance situations.

Key Features

• Grade 316 stainless steel construction for superior chloride and corrosion resistance
• Fully threaded along the entire 4-inch length for maximum engagement flexibility
• 5/8-11 UNC thread form for compatibility with standard hex nuts and couplings
• Uncoated finish - no plating or coating that can flake or introduce contamination
• Meets ASTM B8M standard for stainless steel bolting materials

Compatibility

Designed as an OEM-style replacement or stock fastener for industrial assemblies requiring 5/8-11 fully threaded studs in stainless steel, including flanged piping systems, pump assemblies, and pressure vessel connections.

Installation Notes

Installation is performed by licensed pipefitters, millwrights, or qualified maintenance personnel. Shut down and depressurize any system before removing or installing studs in pressurized service. Use a torque wrench calibrated to the specification required by the flanged joint or equipment manufacturer. Apply anti-seize compound rated for stainless fasteners to prevent galling during installation and future removal.
