Value Collection 93336 Carriage Bolt 1/2-13 2 in Grade 18-8

Product Description

The VALUE COLLECTION 93336 is a 1/2-13 UNC carriage bolt with a 2-inch length under the head, manufactured from Grade 18-8 stainless steel with an uncoated finish. The square neck design locks the bolt in place against the material being fastened, preventing rotation during nut installation. Grade 18-8 stainless steel provides solid corrosion resistance in wet, outdoor, and chemically exposed environments. This bolt is a standard inch-system fastener suited for structural and general-purpose assembly work across construction, fabrication, and maintenance applications.

Carriage bolts in this size range are commonly used in wood-to-wood and wood-to-metal connections, including framing, decking, fencing, and equipment mounting. The round head profile sits flush against the surface without requiring a wrench on the bolt side, making installation straightforward in through-hole applications. The uncoated Grade 18-8 stainless finish makes this bolt appropriate for outdoor, marine-adjacent, and corrosion-sensitive environments where zinc-plated fasteners would be inadequate.

Key Features

• 1/2-13 UNC thread size for broad compatibility with standard nuts and hardware
• 2-inch length under head suits medium-depth through-bolt applications
• Square neck prevents bolt rotation during tightening without a backup tool
• Grade 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Uncoated finish maintains natural stainless appearance with no plating to chip or flake
• Inch measurement system for use with standard imperial hardware

Compatibility

Designed for use with standard 1/2-13 UNC nuts and washers in inch-system fastener applications. Compatible with through-hole connections in wood, metal, and composite materials where a round-head, square-neck carriage bolt configuration is specified.

Installation Notes

Installation typically requires a standard wrench or socket to drive the mating nut while the square neck seats into the substrate to prevent spinning. Ensure the hole diameter is sized to allow the square neck to draw fully into the material without oversizing the bore. Follow applicable structural or building codes when using carriage bolts in load-bearing connections. Minimum order quantity is 25 units per order.
