Value Collection ST1/4-20X1-3/4 Hex Bolt 1/4-20 Ss Pack 5

Product Description

The VALUE COLLECTION ST1/4-20X1-3/4 is a self sealing hex bolt designed for applications requiring a reliable, leak-resistant mechanical fastener. Manufactured from 18-8 stainless steel and passivated for enhanced corrosion resistance, this bolt includes an integrated silicone O-ring that compresses under the head to create a fluid-tight seal without additional sealant compounds. The thread is cut to 1/4-20 UNC specification with a length under head of 1.75 inches. Sold in packs of 5, this fastener suits plumbing, HVAC, and general trade applications where moisture or chemical exposure is present. Installation requires standard hex tooling and no specialized equipment.

This bolt is used in residential and light commercial settings wherever a threaded 1/4-20 UNC fastener must seal against liquid or vapor ingress. Typical applications include panel enclosures, fluid-handling equipment, pump housings, and sheet metal assemblies in HVAC and plumbing systems. The silicone O-ring performs across a wide service temperature range, making it suitable for both hot and cold fluid systems. The passivated 18-8 stainless steel construction resists rust and oxidation in wet or chemically active environments.

Key Features

• Integrated silicone O-ring provides a fluid-tight seal under the bolt head without additional sealant
• 18-8 stainless steel construction with passivation finish for corrosion resistance
• 1/4-20 UNC thread for broad compatibility with standard tapped holes and nuts
• 1.75 inches length under head suits typical panel and housing wall thicknesses
• Sold in packs of 5 for job-lot convenience

Compatibility

Designed as an OEM-style replacement or upgrade fastener for any assembly requiring a 1/4-20 UNC self sealing hex bolt with an 18-8 stainless steel body and silicone O-ring seal.

Installation Notes

Installation is performed by qualified mechanics, plumbers, or HVAC technicians using a standard hex wrench or socket. De-energize equipment and relieve system pressure before replacing any fasteners in pressurized or energized assemblies. Do not overtighten, as excessive torque can deform the silicone O-ring and compromise the seal. Follow applicable codes such as ASME or IFGC for fastener requirements in gas or fluid system enclosures.
