Value Collection 93334 Carriage Bolt 1/2-13 Grade 18-8 Stainless

Product Description

The VALUE COLLECTION 93334 is a 1/2-13 UNC carriage bolt with a 1-inch length under head and a square neck, manufactured from Grade 18-8 stainless steel with an uncoated finish. The square neck seats into the work material to prevent rotation during fastening, eliminating the need for a wrench on the bolt head. Grade 18-8 stainless steel provides solid corrosion resistance for general-purpose indoor and outdoor applications. This fastener is sold individually but carries a minimum order quantity of 25 units, making it suited for contractors and tradespeople sourcing hardware in job-lot quantities.

The 93334 is a standard inch-system carriage bolt used across a wide range of trade and construction applications, including structural connections, equipment mounting, wood-to-metal assemblies, and general mechanical fastening. The 1/2-13 UNC thread size is one of the most common heavy fastener specifications in residential and light commercial construction. Electricians, HVAC technicians, plumbers, and general contractors will encounter this bolt size regularly when securing equipment rails, strut channel, pipe hangers, and access panels.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard nuts and threaded hardware
• 1-inch length under head suits shallow through-fastening applications
• Square neck design prevents bolt rotation during nut tightening without a second tool
• Grade 18-8 stainless steel construction resists rust and corrosion in wet or outdoor environments
• Uncoated finish — no added plating that could affect fit in tight clearance holes
• Inch measurement system; compatible with standard SAE tooling and hardware

Compatibility

Designed as a standard inch-system carriage bolt for use with 1/2-13 UNC nuts and hardware across general construction, mechanical, and trade-installation applications.

Installation Notes

Install using standard hand tools; drive the bolt through a pre-drilled hole sized to allow the square neck to seat flush and lock against rotation before threading the nut. Tighten from the nut side only using an appropriate wrench or socket — do not apply torque to the domed head. For structural or load-bearing connections, follow applicable building codes and engineer specifications. Shut down or de-energize any equipment before fastening hardware in proximity to live electrical or mechanical systems.
