Transhow Fasteners specializes in manufacturing a wide range of bolts, including hex bolts, round head bolts, square head bolts, T-head bolts, dog head bolts, and other custom-designed bolts for special applications.
We supply both metric and inch standard bolts, adhering to standards like DIN, EN, ISO, GB, JIS, AS, UNI, and others. For inch-based products, we follow ASME/ANSI, ASTM/SAE/IFI, BS, and more.
Our bolts are made from materials such as carbon steel, alloy steel, stainless steel, and brass. Bolts below M24 (or 1 inch) are typically cold forged, while larger sizes are hot forged.
To enhance corrosion resistance and strength, our bolts can be treated with various processes such as heat treatment, black oxide, zinc plating, hot-dip galvanizing, black zinc coating, brass coating, nickel and chrome plating, and Dacromet.
