Value Collection ST1/4-20X3 Hex Bolt 1/4-20 3in Ss

Product Description

The VALUE COLLECTION ST1/4-20X3 is a self sealing hex bolt designed for applications where a leak-free fastened joint is required. Built from grade 18-8 stainless steel and passivated for corrosion resistance, this bolt features a silicone O-ring under the head that compresses on installation to seal against fluid or gas intrusion. The 1/4-20 UNC thread and 3-inch length under the head make it a standard choice for plumbing, HVAC enclosures, pool equipment panels, and general mechanical assemblies where moisture or chemical exposure is a concern. Sold in a pack of 5.

This bolt is suited for residential and light commercial trade applications where a standard hex bolt cannot provide an adequate seal at the fastener point. Typical install scenarios include securing access panels on pool pump housings, HVAC equipment enclosures, and plumbing fixture brackets exposed to water or humid environments. The passivated 18-8 stainless steel construction holds up in wet and mildly corrosive service conditions without the need for additional sealant tape or thread compound at the bolt head.

Key Features

• Self sealing design with silicone O-ring under the head eliminates the need for additional head sealant
• Grade 18-8 stainless steel construction with passivation treatment for corrosion resistance
• 1/4-20 UNC thread standard for broad fastener compatibility
• 3-inch length under the head suits moderate panel and bracket thickness applications
• Pack of 5 units per order

Compatibility

Designed as an OEM-style replacement or service fastener for equipment requiring a 1/4-20 UNC self sealing hex bolt with a 3-inch length under head in 18-8 stainless steel.

Installation Notes

Installation is performed by qualified tradespeople using standard hex drive tools appropriate for the bolt head size. Power down or depressurize any system before replacing fasteners on live equipment. Do not overtighten, as excessive torque can damage or displace the silicone O-ring and compromise the seal. Verify thread engagement depth and O-ring seating visually before returning the assembly to service.
