Value Collection ST1/2-13X2 Hex Bolt 1/2-13 Unc 2in Ss Pack of 5

Product Description

The VALUE COLLECTION ST1/2-13X2 is a self sealing hex bolt designed for applications where a fluid-tight or pressure-resistant fastener connection is required. The bolt features a 1/2-13 UNC thread profile and measures 2 inches in length under the head. It is manufactured from 18-8 grade stainless steel and receives a passivation treatment to maximize corrosion resistance. A silicone O-ring is incorporated at the bearing surface to create a seal when the fastener is torqued down. This bolt is installed by millwrights, pipefitters, maintenance technicians, and mechanical contractors working on equipment that demands both structural fastening and leak prevention at the fastener point.

This bolt is suited for use in fluid system enclosures, pump housings, manifolds, and mechanical assemblies where standard hex bolts would allow seepage around the fastener hole. The 18-8 stainless steel construction makes it appropriate for wet, outdoor, or mildly corrosive environments. The UNC thread form is the standard inch-series coarse thread, widely compatible with tapped holes and nuts in industrial and HVAC equipment. Sold in a pack of 5 with a minimum order quantity of 1 pack.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard inch-series tapped holes
• 2 inches length under head for typical medium-depth fastening applications
• 18-8 stainless steel construction with passivation treatment for corrosion resistance
• Integrated silicone O-ring provides a leak-resistant seal at the bearing surface
• Pack of 5 fasteners per package with no minimum beyond a single pack

Compatibility

Designed as an OEM-style replacement or direct installation fastener for fluid system enclosures, pump housings, and mechanical assemblies requiring a 1/2-13 UNC self sealing hex bolt with a 2-inch grip length in 18-8 stainless steel.

Installation Notes

Installation is performed by qualified mechanical or pipefitting trades using a standard hex wrench or socket. Ensure the mating tapped hole is clean and free of debris before threading to avoid damaging the O-ring. Do not overtorque — excessive torque will deform or extrude the silicone O-ring and compromise the seal. Follow applicable equipment manufacturer torque specifications and relevant code requirements for the system being serviced.
