Value Collection 3SBC904C0208 Carriage Bolt 1/4-20 2.5in

Product Description

The VALUE COLLECTION 3SBC904C0208 is a 1/4-20 UNC carriage bolt with a 2.5 inch length under head and a square neck drive style. Manufactured from 18-8 stainless steel with a bright uncoated finish, this fastener delivers corrosion resistance suitable for both indoor and outdoor applications. The square neck seats flush into timber, plate, or structural material to prevent rotation during nut tightening without requiring a secondary tool on the bolt head. Installers in construction, mechanical assembly, and maintenance trades reach for this bolt when a clean round-head profile and tamper-resistant underside are required. The 18-8 alloy grade provides a reliable balance of strength and weldability for general-purpose fastening tasks.

This carriage bolt is suited for light structural connections, wood-to-metal assemblies, equipment mounting, and general fabrication work across residential and commercial job sites. The 1/4-20 UNC thread pattern is one of the most common inch-series thread standards, ensuring compatibility with widely available nuts, washers, and hardware. The uncoated bright finish is appropriate for applications where galvanic concerns with dissimilar metals are managed separately or where post-installation coating will be applied by the installer.

Key Features

• 1/4-20 UNC thread for broad hardware compatibility
• 2.5 inch length under head suits medium-depth through-bolt applications
• Square neck prevents bolt rotation during installation without a wrench on the head
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Bright uncoated finish with no added plating or coating
• Inch measurement system for standard US fastener applications

Compatibility

Designed as a standard 1/4-20 UNC inch-series carriage bolt for use with compatible 1/4-20 hex nuts, flat washers, and lock washers in general structural and mechanical fastening applications.

Installation Notes

Insert the bolt through a pre-drilled hole sized to allow the square neck to seat and lock against the material surface. Drive the nut down with a wrench while the square neck holds the bolt stationary. Always confirm hole diameter is appropriate for the thread size to ensure proper neck seating. Stainless steel fasteners can be susceptible to galling during installation — apply an appropriate anti-seize compound to the threads if repeated removal is anticipated.
