Value Collection R50000204 Carriage Bolt 5/8-11 Unc

Product Description

The VALUE COLLECTION R50000204 is a standard carriage bolt designed for general-purpose fastening applications across construction, mechanical, and structural assembly work. It features a 5/8-11 UNC thread specification with a 2.5-inch length under head and a square neck that resists rotation during installation. Manufactured from Grade 2 steel with a zinc-plated finish, this bolt meets ASTM A307 standards for general structural fastening. It is a common choice for wood-to-wood and wood-to-metal connections where a smooth, domed head is required on the finished face.

This carriage bolt is suited for residential and light commercial construction, fencing, framing, and equipment assembly. The square neck seats into wood or soft substrates to prevent spinning as the nut is tightened, allowing single-side installation without a secondary wrench on the bolt head. Tradespeople working in carpentry, general contracting, electrical infrastructure mounting, and pool equipment framing commonly use this bolt type for structural tie-down and component mounting tasks.

Key Features

• 5/8-11 UNC thread form for broad nut and hardware compatibility
• 2.5-inch length under head suits standard structural fastening depths
• Standard square neck prevents rotation during single-side nut tightening
• Grade 2 steel construction meets ASTM A307 requirements
• Zinc-plated finish provides basic corrosion resistance for general use

Compatibility

Designed as a standard-duty replacement or general-stock carriage bolt for applications requiring a 5/8-11 UNC thread and 2.5-inch under-head length in wood, composite, or compatible metal substrates.

Installation Notes

Installation is typically performed by contractors, carpenters, or trade technicians using a standard wrench or socket on the nut side only. Insert the bolt through the pre-drilled hole so the square neck seats fully into the substrate before applying the washer and nut. Do not drive the bolt head with a hammer once the square neck is seated, as this can deform the shank. Follow applicable building codes and structural specifications when using fasteners in load-bearing assemblies.
