Dan-loc Bolt Gasket 130-04-030 Fully Threaded Stud

Product Description

The DAN-LOC BOLT GASKET 130-04-030 is a fully threaded stud machined from 316 stainless steel with a plain, uncoated finish. It carries a 1/2-13 unified coarse thread and measures 3 inches overall length. The fully threaded design runs threads from end to end, providing maximum engagement flexibility when fastening two components or anchoring into a tapped hole. This stud meets ASTM B8M standards, which govern stainless steel fasteners for high-strength and corrosion-resistant applications. Licensed tradespeople in HVAC, plumbing, and mechanical systems rely on this type of fastener when corrosion resistance is a primary design requirement.

This stud is suited for use in wet environments, chemical-exposed assemblies, and marine or coastal installations where carbon steel fasteners would corrode prematurely. Common applications include pipe flange assemblies, pump mounting, pressure vessel hardware, and equipment enclosures exposed to moisture or cleaning agents. The 316 stainless steel alloy provides superior chloride resistance compared to 304 grades, making it a practical choice for coastal HVAC equipment pads, pool mechanical rooms, and similar corrosive service environments.

Key Features

• Fully threaded from end to end for maximum engagement versatility
• 316 stainless steel construction for superior corrosion and chloride resistance
• 1/2-13 unified coarse thread for broad nut and hardware compatibility
• Meets ASTM B8M standard for stainless steel fasteners
• Uncoated plain finish - no plating to degrade in corrosive service
• 3 inches overall length suits a wide range of flange and mounting applications

Compatibility

Designed as a direct-fit threaded fastener for any application requiring a 1/2-13 unified coarse thread stud in 316 stainless steel with a 3-inch overall length.

Installation Notes

Installation of threaded studs is typically performed by licensed plumbers, pipefitters, or mechanical contractors working under applicable ASME or IFGC fastener and pressure-system codes. Confirm thread engagement depth and mating nut grade before assembly, ensuring compatibility with 316 stainless steel to avoid galvanic corrosion from dissimilar metals. Use calibrated torque tools appropriate for the joint specification - do not over-torque stainless fasteners, as galling can occur without proper anti-seize compound. De-energize and depressurize any system before removing or replacing load-bearing fasteners.
