Value Collection ST1/4-20X1 Self Sealing Hex Bolt 1/4-20

Product Description

The VALUE COLLECTION ST1/4-20X1 is a self sealing hex bolt designed for applications where fastener joints must resist fluid intrusion or pressure leakage. The bolt features a silicone O-ring seated beneath the head that compresses against the mating surface on installation, creating a seal without a separate gasket. The 18-8 stainless steel construction provides corrosion resistance in wet, chemical-exposed, or outdoor environments. Passivated after manufacturing, the surface finish enhances oxide layer integrity for added corrosion protection. This fastener is used by HVAC technicians, plumbers, electricians, and general contractors where a sealed mechanical connection is required in metal or rigid substrate assemblies.

This bolt is suited for residential and light commercial applications where standard hex bolts would allow moisture, refrigerant, or fluid migration through the fastener hole. Typical installation scenarios include equipment enclosures, junction boxes, fluid handling assemblies, and any bolted joint requiring a low-profile seal. The 1/4-20 UNC thread pattern is one of the most common fastener sizes in trade work, making this bolt a direct fit in a wide range of existing tapped holes and threaded inserts. Sold in a package of 5 per order.

Key Features

• Integrated silicone O-ring provides a fluid-tight seal at the bolt head without a separate gasket
• 18-8 stainless steel construction resists corrosion in wet and chemical-exposed environments
• Passivated surface finish enhances corrosion resistance beyond standard stainless steel
• 1/4-20 UNC thread pattern for broad compatibility with standard tapped holes and threaded inserts
• Hex drive head for use with standard wrenches and sockets
• Sold in packs of 5 to support single-job and multi-fastener applications

Compatibility

Designed as a general-purpose self sealing hex bolt for use in any application requiring a 1/4-20 UNC threaded fastener with an integrated O-ring seal at the clamping face.

Installation Notes

Installation does not require special tools beyond a standard hex wrench or socket sized for a 1/4-inch hex bolt head. Ensure the mating surface is clean and flat so the silicone O-ring seats evenly and forms a complete seal. Do not overtighten, as excessive torque can damage or extrude the O-ring and compromise the seal. Verify thread engagement depth in the receiving material before applying full fastening load.
