IMSCREWS 3/8"-16 x 2" Heavy-Duty 304 Stainless Steel Carriage Bolts (20 PCS)

Substantial Strength for Structural Timber and Outdoor Projects
The IMSCREWS 3/8" x 2" carriage bolt is engineered for structural projects requiring significant load-bearing capacity and a professional finish. With a robust 3/8-inch diameter and a precise 2-inch length, these bolts are the ideal choice for securing deck railings, heavy-duty fencing, and timber-to-metal connections. The 2-inch length is perfectly suited for passing through standard 2x lumber (actual 1.5" thickness) while leaving sufficient thread to accommodate structural washers and hex nuts for a snug, permanent connection. Built for durability, they offer the stability required for outdoor pergolas, residential gates, and heavy timber framing.

High Durability and Safety-Focused Design
Forged from premium 18-8 (304) stainless steel, these fasteners offer superior resistance to rust and corrosion in coastal or humid environments. The smooth round head creates a clean, low-profile appearance that reduces snagging hazards, making them a safe choice for high-traffic areas like playground equipment, benches, and residential decks. The integrated square neck locks the bolt into place, preventing spinning and allowing for easy, one-sided tightening from the nut side with a single wrench.

Pro-Tips:
1. Use a 3/8" drill bit to ensure a snug, structural fit for the square neck.
2. Pair with stainless steel flat washers and hex nuts on the nut side to distribute heavy structural loads and protect wood fibers.

Key Features
