Value Collection 3sbc904c0200 Carriage Bolt 1/4-20 Unc

Product Description

The VALUE COLLECTION 3sbc904c0200 is a 1/4-20 UNC carriage bolt with a 2-inch length under head and a standard square neck, manufactured from 18-8 stainless steel with no coating applied. The square neck seats into a pre-drilled hole and locks the fastener in place during tightening, eliminating the need to hold the bolt head. Built from 18-8 stainless steel, this bolt resists corrosion in wet, outdoor, and chemically exposed environments. It weighs approximately 0.01 pounds. This bolt is suited for general mechanical assembly, structural connections, and equipment fabrication work performed by plumbers, HVAC technicians, electricians, and other trade professionals who require a reliable, corrosion-resistant threaded fastener.

This carriage bolt is used in a wide range of trade and light industrial applications where a flush, round-head fastener with anti-rotation neck is required. Common install scenarios include mounting brackets, securing equipment panels, assembling structural frames, and attaching fixtures to wood or metal substrates. The uncoated 18-8 stainless steel construction makes it appropriate for both indoor and outdoor use in corrosive or high-moisture environments typical in HVAC, plumbing, and pool service work.

Key Features

• 1/4-20 UNC thread form for compatibility with standard 1/4-20 nuts and tapped holes
• 2-inch length under head provides consistent grip range for typical bracket and panel assemblies
• Standard square neck prevents bolt rotation during nut tightening without requiring a wrench on the head
• 18-8 stainless steel construction resists corrosion in wet and outdoor service conditions
• Uncoated finish suitable for use where coatings could interfere with fit or torque

Compatibility

Designed as an OEM-style and general-use replacement carriage bolt for applications requiring a 1/4-20 UNC thread, 2-inch under-head length, and standard square neck profile in 18-8 stainless steel.

Installation Notes

Installation is performed by the appropriate trade professional or mechanic using standard hand tools. Before installation, ensure the substrate hole diameter matches the bolt shank and that the square neck recess is properly formed to seat the neck and prevent rotation. Tighten the mating nut to the assembly specification for the application; do not over-torque stainless steel fasteners, as galling can occur. Follow applicable mechanical and structural codes for the installation environment.
