Value Collection ST1/2-13X1-1/4 Hex Bolt 1/2-13 Ss

Product Description

The VALUE COLLECTION ST1/2-13X1-1/4 is a self sealing hex bolt engineered for applications that require a reliable fluid or gas-tight fastened joint. Built from 18-8 stainless steel with a passivated finish, the bolt resists corrosion in wet and chemical environments. It features a silicone O-ring seated under the head that compresses on installation to create a leak-resistant seal without a separate gasket. Thread size is 1/2-13 UNC with a length under head of 1.25 inches. This fastener is installed by licensed plumbers, pipefitters, HVAC technicians, and industrial maintenance mechanics wherever a standard hex bolt needs an integrated sealing element.

Self sealing hex bolts in this size range are used in residential and light commercial HVAC assemblies, plumbing manifolds, equipment access covers, fluid handling enclosures, and general industrial panel fastening. The 1/2-13 UNC thread pattern is one of the most common coarse-thread sizes in North American mechanical systems, making this bolt a straightforward replacement in a wide range of existing tapped holes. The passivated 18-8 stainless steel construction is appropriate for outdoor, humid, or mildly corrosive service environments. This listing contains five bolts per package.

Key Features

• Integrated silicone O-ring under the head provides a leak-resistant seal on installation
• 18-8 stainless steel construction with passivated finish for corrosion resistance
• 1/2-13 UNC coarse thread for compatibility with standard North American tapped holes
• 1.25-inch length under head suits medium-depth fastening applications
• Hex drive head accepts standard wrenches and sockets — no specialty tools required
• Sold in a pack of 5 to support single-service or small batch jobs

Compatibility

Designed as an OEM-style replacement or aftermarket fastener for any application requiring a 1/2-13 UNC self sealing hex bolt with an 18-8 stainless steel body and silicone O-ring seal.

Installation Notes

Installation is performed by a qualified mechanic, plumber, or HVAC technician using a standard combination wrench or socket set sized for a 1/2-13 hex bolt head. Depressurize and de-energize the system before removing or installing any fastener in a pressurized fluid or gas assembly. Avoid over-torquing, as excessive force will deform or extrude the silicone O-ring and compromise the seal. Confirm that the mating tapped hole is clean and free of debris before threading in the bolt.
