Dan-loc Bolt Gasket 110-04-030 Fully Threaded Stud 1/2-13

Product Description

The DAN-LOC BOLT GASKET 110-04-030 is a fully threaded stud machined from 304 stainless steel with a 1/2-13 UNC thread form and an overall length of 3 inches. Unlike a standard cap screw or bolt, a fully threaded stud has no head - it threads into a tapped hole or is secured with nuts on both ends, distributing clamping load evenly across the full shank. The uncoated, plain finish is standard for stainless applications where corrosion resistance comes from the base alloy rather than a surface treatment. Licensed plumbers, pipefitters, and mechanical contractors reach for this fastener when assembling flanged connections, pump housings, pressure vessels, or equipment mounting assemblies that demand corrosion-resistant hardware.

This stud is suited for use in wet, corrosive, or outdoor environments where carbon steel fasteners would deteriorate. Common applications include plumbing and HVAC equipment mounting, water treatment systems, pool and spa mechanical connections, and general industrial assembly work requiring stainless fasteners. The 1/2-13 thread size is one of the most widely used coarse-thread specifications in North American trade applications, making this stud a straightforward match for standard pipe flanges and equipment frames.

Key Features

• 304 stainless steel construction provides corrosion resistance without a surface coating
• 1/2-13 UNC coarse thread - common standard pitch for structural and mechanical fastening
• Fully threaded along the entire 3-inch length, maximizing thread engagement in blind or through applications
• Uncoated plain finish - no plating to crack, flake, or react with process media
• Meets ASTM B8 standards for stainless steel fasteners

Compatibility

Designed as an OEM-style replacement or direct-use fastener for applications requiring a 1/2-13 fully threaded stud in 304 stainless steel with a 3-inch overall length.

Installation Notes

Installation of threaded studs typically requires two jam nuts or a stud installation tool to drive the stud into the tapped hole without damaging threads. Always verify the mating thread is clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize compound as required by the application. Stainless steel fasteners are susceptible to galling - use care when torquing and consider anti-seize to reduce friction between mating stainless surfaces.
