Transhow Fasteners is a professional manufacturer of various types of bolts, including hex bolts, round head bolts, square head bolts, T-head bolts, dog head bolts, and other customized and special-purpose bolts. We produce both metric and inch standard bolts, complying with international standards such as DIN, EN, ISO, GB, JIS, AS, UNI, etc., as well as ASME/ANSI, ASTM/SAE/IFI, BS, and more.
Our bolts are made from high-quality materials like 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 meet different corrosion resistance and strength requirements, our bolts can be further treated with processes such as heat treatment, black oxide, zinc plating, hot-dip galvanizing, black zinc coating, brass plating, nickel and chrome plating, and Dacomate.
For structural applications, we also offer High Strength Heavy Hex Bolts and Structure Bolts designed for steel-to-steel connections in buildings, highways, railways, and bridges. These bolts are usually paired with heavy hex nuts. The material used for these bolts and nuts is generally medium carbon steel or alloy steel, and they are often finished with black oxide or hot-dip galvanizing.
Standard products include:
- DIN 6914: High-strength hexagon head bolts with large widths across flats for structural steel bolting
- DIN 7990: Steel hexagon head bolts for structural steel bolting, supplied with hexagon nuts
- ISO 7411 / ISO 7412: Hexagon bolts for high-strength structural bolting with large width across flats
