Product Description

The 3/4-10*3-3/4 heavy-duty fastener is a high-strength 3/4-10 UNC bolt designed for industrial applications requiring robust mechanical connections. Featuring a 3-3/4" hex bolt configuration with a 3/4-10 carriage fastener thread profile, it provides secure fastening in machinery assembly, structural frameworks, and automotive systems. The bolt operates in standard industrial environments with temperatures ranging from -40°C to 120°C. Its zinc-plated steel construction ensures corrosion resistance, while the hexagonal head allows for easy torque application. Ideal for load-bearing applications, this fastener excels in vibration resistance and durability but may require specialized tools for installation. Commonly used in manufacturing, construction, and heavy equipment industries, it supports static and dynamic loads without compromising structural integrity.
