IMSCREWS 1/2"-13 x 1-1/2" Heavy-Duty 304 Stainless Steel Carriage Bolts (5 PCS)

Substantial Strength for Heavy-Duty Structural Connections
The IMSCREWS 1/2" x 1-1/2" carriage bolt is engineered for structural projects requiring extreme shear resistance and reliable load-bearing support. With a robust 1/2-inch diameter and a 1.5-inch length, these bolts are well-suited for high-stress joints where stability is critical, such as mounting heavy hinges, securing large metal brackets, or reinforcing timber-to-metal connections. Built for durability, they offer the stability necessary for long-term use in demanding residential, commercial, and marine applications.

High Durability and Security-Focused Design
Forged from premium 18-8 (304) stainless steel, these fasteners are highly resistant to rust and corrosion in coastal or humid environments. The smooth round head offers a clean appearance that reduces snagging hazards, making them an ideal choice for visible railings, heavy-duty benches, and playground equipment. The integrated square neck prevents the bolt from spinning, allowing for easy, one-sided installation with a single wrench from the nut side.

Specifications:
- Thread Size: 1/2"-13 Coarse (UNC); Length: 1-1/2" (Measured from Under Head)

Pro-Tips:
1. Use a 1/2" 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 structural load and protect material surfaces.

Key Features

• Industrial-Strength 1/2 Diameter: The robust 0.5-inch shank provides maximum shear resistance and load-bearing capacity, specifically engineered for high-stress structural joints.
• Optimized Mid-Range Length: The 1.5-inch length is the professional choice for mounting thick metal plates or heavy-duty hardware to standard dimension lumber without excessive tailing.
• Marine-Grade 304 Stainless: Forged from premium 18-8 (304) stainless steel, ensuring professional-grade defense against rust in humid outdoor, coastal, or agricultural settings.
• Tamper-Proof Security Head: The smooth, rounded dome head eliminates drive slots, preventing unauthorized loosening and providing a clean finish for public gates and fences.
