Value Collection ST5/16-18X1-1/2 Hex Bolt 5/16-18 Ss 5pk

Product Description

The VALUE COLLECTION ST5/16-18X1-1/2 is a self sealing hex bolt designed for applications requiring a secure, leak-resistant fastener. Manufactured from 18-8 stainless steel and passivated for enhanced corrosion resistance, this bolt features a silicone O-ring under the head that compresses on installation to form a tight seal against fluid or gas migration. The 5/16-18 UNC thread and 1-1/2 inch length under head make it a practical fastener for a wide range of mechanical, plumbing, and equipment assembly tasks. Each package contains 5 bolts. Installation requires a standard hex wrench or socket driver appropriate for the bolt head size.

This self sealing hex bolt is suited for use in HVAC equipment panels, pump housings, enclosures, and other assemblies where preventing moisture or fluid ingress at the fastener point is important. The passivated 18-8 stainless steel construction resists rust and chemical exposure, making it appropriate for both indoor and outdoor installations, as well as wet or corrosive environments common in plumbing and pool service applications. Typically installed by HVAC technicians, plumbers, and mechanical contractors during equipment assembly or repair.

Key Features

• Silicone O-ring under head creates a compression seal to prevent fluid or gas leakage at the fastener point
• 18-8 stainless steel construction provides corrosion and rust resistance
• Passivated finish enhances surface corrosion resistance beyond standard stainless steel
• 5/16-18 UNC thread for broad compatibility with standard inch-series hardware
• 1-1/2 inch length under head suits medium-depth fastening applications
• Sold in a pack of 5 bolts

Compatibility

Designed as an OEM-style replacement or general-use fastener for any application requiring a 5/16-18 UNC self sealing hex bolt with an 18-8 stainless steel body and silicone O-ring seal.

Installation Notes

Install using a properly sized hex socket or open-end wrench. Power down and depressurize any system before replacing fasteners on pressurized assemblies. Do not overtighten, as excessive torque can deform or damage the silicone O-ring and compromise the seal. Follow applicable mechanical and plumbing codes for the installation environment.
