Dan-loc Bolt Gasket 130-04-025 Fully Threaded Stud

Product Description

The DAN-LOC BOLT GASKET 130-04-025 is a fully threaded stud machined from 316 stainless steel to an overall length of 2.5 inches with a 1/2-13 UNC thread form. The uncoated finish exposes the base material directly, making it suitable for applications where corrosion resistance is the primary concern rather than aesthetics. Meeting ASTM B8M standards, this stud is rated for use in corrosive and high-moisture environments common in industrial, marine, plumbing, and mechanical piping assemblies. Licensed tradespeople and maintenance technicians install fully threaded studs where a double-nut or insert fastening method is required in place of a standard bolt.

This stud is suited for residential and commercial mechanical applications requiring reliable fastening in wet, chemical-exposure, or outdoor environments. The 1/2-13 thread pitch is a standard coarse-thread designation widely used in flanged pipe connections, pump housings, HVAC equipment mounting, and general structural assemblies. The 316 stainless steel grade provides enhanced resistance to chlorides and acidic media compared to 304-grade material, making it a common choice in coastal installations and process piping environments.

Key Features

• Fully threaded along the entire 2.5-inch length for maximum engagement flexibility
• 316 stainless steel construction for superior corrosion resistance in chloride-rich and chemical environments
• 1/2-13 UNC thread size - a widely standardized coarse-thread pitch
• Uncoated finish exposes raw 316 material for applications where coatings may be incompatible
• Meets ASTM B8M standards for stainless steel bolting materials
• UNSPSC Code 31161618 for procurement and catalog classification

Compatibility

Designed as an OEM-style replacement or new-installation fastener for assemblies requiring a 1/2-13 fully threaded stud in 316 stainless steel with an overall length of 2.5 inches.

Installation Notes

Installation of threaded studs typically falls within the scope of licensed plumbers, pipefitters, or mechanical contractors depending on the application. Power down or isolate the system and relieve any line pressure before removing or replacing fasteners in pressurized assemblies. Use appropriate thread lubricant or anti-seize compound rated for stainless steel to prevent galling during installation. Torque to the specifications required by the equipment manufacturer or governing code - do not estimate from general fastener charts alone.
