IMSCREWS 1/2"-13 x 1" Heavy-Duty 304 Stainless Steel Carriage Bolts (10 PCS)

Substantial Strength for Heavy Structural and Automotive Applications
The IMSCREWS 1/2" x 1" carriage bolt is engineered for high-load structural projects that demand maximum stability in a compact form. With a robust 1/2-inch diameter and a strategic 1-inch length, these bolts are the ideal choice for securing bumper brackets, heavy-duty metal plates, and dock hardware. The short-reach design is perfectly suited for joining thin yet heavy materials, providing a snug connection without excessive thread protrusion. Built for longevity, they offer the structural integrity required for heavy machinery, playground sets, and commercial-grade timber framing.

Superior Durability and Safety-Focused Design
Forged from premium 18-8 (304) stainless steel, these fasteners offer superior resistance to rust and corrosion, even when exposed to harsh coastal or humid environments. The smooth round head creates a clean, tamper-resistant look that reduces snagging hazards, making them a safe choice for high-traffic areas like public parks, residential decks, and vehicle assemblies. The integrated square neck locks the bolt into place during installation, preventing spinning and allowing for easy, one-sided tightening from the nut side with a single wrench.

Pro-Tips:
1. Use a 1/2" drill bit to ensure a snug, structural fit for the square neck.
2. Pair with 304 SS flat washers and hex nuts on the nut side to distribute heavy structural loads and protect the base material.
