We use modern continuous atmosphere controlled heat treatment facilities to produce quality heat-treated threaded high-tensile fasteners. Heat Treated Fastenings are manufactured to Chinese standard specification or as per customer's requirement. Our product ranges between 18mm to 24mm in diameter and 50mm to 200 mm in length. The head is hot forged and the threads are either cut or rolled as per the client's requirement. Send us your drawings or e-mail your concept or idea to us and we will work with you to custom design your parts. Look forward to hearing from you eagerly!
