Value Collection CAI506202000-025BX Carriage Bolt 5/8-11 2in

Product Description

The VALUE COLLECTION CAI506202000-025BX is a 5/8-11 carriage bolt with a 2-inch length under head, manufactured from Grade 5 steel with a zinc-plated finish. The square neck beneath the dome head is designed to seat into wood or metal and resist rotation during tightening without requiring a wrench on the bolt end. This bolt follows Unified National Coarse (UNC) thread standards and is measured by length under head per standard inch fastener conventions. It is a general-purpose structural fastener suited for mechanical assemblies, wood connections, and light fabrication work across construction, HVAC equipment mounting, and general trade applications.

This carriage bolt is used in residential and commercial construction, equipment framing, and mechanical installations where a flush, rounded bolt head and self-locking square neck are required. Common applications include securing wooden structural members, attaching brackets to framing, and fastening components in equipment enclosures. The zinc plating provides moderate corrosion resistance for indoor and sheltered outdoor environments. Trade professionals in HVAC, plumbing, and general construction regularly use this fastener size for equipment bases, platform framing, and panel attachments.

Key Features

• 5/8-11 UNC thread provides coarse-pitch engagement suited for wood and general structural connections
• Grade 5 steel construction meets medium-strength fastener requirements for structural assemblies
• Zinc-plated finish offers corrosion resistance in indoor and sheltered installations
• Square neck under dome head locks into substrate to prevent bolt rotation during nut tightening
• 2-inch length under head fits standard framing and bracket connection depths

Compatibility

Designed as a standard inch-series UNC carriage bolt for use in wood, metal, and composite assemblies requiring a 5/8-11 thread and 2-inch under-head length.

Installation Notes

Installation is typically performed by carpenters, ironworkers, HVAC mechanics, or general tradespeople using a standard wrench or socket on the nut side only. Pre-drill a hole sized to allow the square neck to seat flush and grip the substrate before tightening. Power down or de-energize any equipment before fastening components to live electrical enclosures or mechanical systems. Do not exceed the load ratings appropriate for Grade 5 fasteners in the application.
