Value Collection C31273 Carriage Bolt 1/4-20 1-1/4 in 18-8 Ss

Product Description

The VALUE COLLECTION C31273 is a 1/4-20 UNC carriage bolt with a 1-1/4 inch length under head, manufactured from 18-8 stainless steel with a bright uncoated finish. The square neck design seats flush into a pre-drilled hole and resists rotation during tightening, eliminating the need for a wrench on the bolt head. The 18-8 stainless steel construction provides corrosion resistance suitable for wet, outdoor, and light chemical environments. This fastener is used by electricians, plumbers, HVAC technicians, and general trade contractors wherever a tamper-resistant, corrosion-resistant through-bolt is required.

This carriage bolt is suited for light-duty structural and mechanical connections in residential and commercial trade applications. Common uses include mounting brackets, equipment supports, electrical enclosures, and utility panel attachments. The inch-standard 1/4-20 thread is one of the most commonly specified fastener sizes across HVAC, plumbing, and electrical support hardware, making this bolt a straightforward drop-in for standard hardware applications where stainless steel corrosion resistance is specified.

Key Features

• 1/4-20 UNC thread standard for broad compatibility with standard nuts and hardware
• 1-1/4 inch length under head suits light-duty panel and bracket connections
• 18-8 stainless steel construction resists rust and corrosion in wet or outdoor environments
• Square neck design locks bolt in place during installation without a secondary tool on the head
• Bright uncoated finish — no coating to chip, flake, or interfere with grounding continuity

Compatibility

Designed as a standard 1/4-20 UNC carriage bolt for use with any compatible 1/4-20 nut and standard hardware in inch-measurement fastener applications.

Installation Notes

Installation requires a pre-drilled hole sized to allow the square neck to seat fully and prevent rotation. A torque wrench and appropriate 1/4-20 nut and washer should be used to achieve proper clamping force per the equipment manufacturer or structural specification. Power down or de-energize any equipment before fastening near electrical components. Follow applicable NEC or IPC guidelines when using fasteners in code-governed installations.
