Value Collection A996077 Carriage Bolt 3/8-16 3-1/2 in 25 Pack

Product Description

The VALUE COLLECTION A996077 is a 3/8-16 carriage bolt designed for general fastening applications requiring corrosion-resistant hardware. Featuring a square neck below the domed head, this bolt resists rotation as it is drawn into wood or soft material, allowing a nut to be tightened from one side without a wrench on the bolt head. Manufactured from Grade 18-8 stainless steel with an uncoated finish, it offers solid resistance to rust and oxidation in wet or outdoor environments. Thread size is 3/8-16 UNC with a length under head of 3.5 inches. Sold in a package of 25.

This carriage bolt is suited for structural connections in residential construction, decking, fencing, and general fabrication where stainless hardware is specified. The UNC thread pattern is compatible with standard 3/8-16 nuts and is appropriate for use in wood-to-wood and wood-to-metal assemblies. Tradespeople, contractors, and maintenance technicians commonly stock this fastener for corrosion-sensitive installations such as dock hardware, exterior framing, and equipment mounting in damp locations.

Key Features

• Grade 18-8 stainless steel construction for corrosion and oxidation resistance
• 3/8-16 UNC thread for compatibility with standard nuts and hardware
• 3.5-inch length under head suits medium-depth fastening applications
• Square neck below the head locks into material to prevent bolt rotation during tightening
• Uncoated finish — no plating to chip, flake, or introduce galvanic incompatibility with stainless hardware
• Sold in a 25-piece package for small-run jobs and inventory replenishment

Compatibility

Designed as a standard 3/8-16 UNC carriage bolt compatible with any hex nut, coupling nut, or washer rated for 3/8-16 thread, including stainless steel and 18-8 grade fastener hardware.

Installation Notes

Carriage bolts are typically installed by a carpenter, contractor, or maintenance technician using a drill to pre-bore a clearance hole sized to the bolt shank. The square neck must seat fully into the substrate material before applying a washer and nut to the threaded end. Do not attempt to install by driving through material that will not allow the square neck to seat — spinning under load will prevent proper clamping force. Follow applicable building codes and hardware specifications for structural fastening applications.
