Substantial Strength for Compact Heavy-Duty Connections The IMSCREWS 1/2" x 1" carriage bolt is engineered for structural projects requiring maximum shear resistance in a compact, low-profile size. With a robust 1/2-inch diameter and a 1-inch length, these bolts are well-suited for joints where load-bearing stability is critical but clearance is limited, such as mounting heavy-duty metal brackets to thin structural panels or reinforcing industrial hardware. Built for durability, they offer the stability necessary for long-term use in demanding residential and commercial projects.
High Durability and Safety-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 joints on docks, trailers, and heavy outdoor furniture. 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" (Measured from Under Head) - Material: 304 (18-8) Stainless Steel; Full Thread
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 nuts on the nut side to distribute structural load and protect material surfaces.
Key Features
Industrial-Grade Shear Strength: The massive 1/2-inch diameter provides exceptional load-bearing capacity and shear resistance, making these bolts ideal for heavy-duty structural brackets.
Compact Heavy-Duty Mounting: The short 1-inch length is specifically designed for securing thick metal plates or heavy hardware to timber without excessive bolt protrusion.
Marine-Grade 304 Stainless: Forged from premium 18-8 (304) stainless steel, offering maximum defense against rust in high-moisture outdoor and industrial environments.
Tamper-Resistant Security: The smooth, domed round head features no drive socket, preventing unauthorized removal while providing a clean, snag-free professional finish.
Self-Locking Square Neck: The heavy-duty square shoulder bites firmly into pre-drilled holes, locking the bolt in place for effortless, one-sided high-torque tightening.
