Value Collection ST3/8-16X1-1/2 Hex Bolt 3/8-16 Ss

Product Description

The VALUE COLLECTION ST3/8-16X1-1/2 is a self sealing hex bolt designed for applications that require a reliable, 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 create a positive seal against moisture and fluid intrusion. The 3/8-16 UNC thread pattern and 1.5-inch length under head make it a practical choice for HVAC enclosure panels, plumbing fixture mounting, pool equipment housings, and other assemblies exposed to wet or corrosive environments. Sold in a pack of 5.

This bolt is suited for residential and light commercial trade applications where a standard hex bolt would allow moisture ingress at the fastener point. Typical scenarios include mounting panels on outdoor HVAC equipment, securing access covers on pool pump housings, and fastening components in environments with frequent washdown or standing moisture. The passivated 18-8 stainless steel construction holds up to mild chemical exposure and resists rust without additional coating. Installation is straightforward with standard hex tooling.

Key Features

• Silicone O-ring under head creates a self-sealing barrier against moisture and fluid intrusion
• 18-8 stainless steel construction offers corrosion resistance for wet and outdoor environments
• Passivated finish enhances surface corrosion resistance beyond standard stainless
• 3/8-16 UNC thread standard ensures broad compatibility with standard tapped holes
• 1.5-inch length under head suits medium-depth fastening applications
• Pack of 5 allows single-job stock without over-ordering

Compatibility

Designed as an OEM-style replacement or service fastener for any assembly using 3/8-16 UNC threaded holes where a self sealing hex bolt is specified.

Installation Notes

Installation is performed by licensed technicians or qualified tradespeople working on mechanical enclosures, panels, or equipment housings. Power down or de-energize any associated equipment before removing or replacing fasteners on electrical or HVAC panels. Hand-start threads before applying hex tooling to avoid cross-threading, and seat the bolt until the silicone O-ring is visibly compressed and flush — do not overtighten, as excessive torque can deform or damage the O-ring seal. Follow applicable mechanical or building codes for fastener material requirements in corrosive or outdoor-rated installations.
