Professional partner in custom made fastener industry. We manufacture all standard head styles, but our specialty is in custom engineered products.
Cold Heading,which is also called cold forming, is a fast and more efficient process to produce both standard bolts and custom fasteners. The cold heading technology has been in existence for over 150 years. Your bolts and fasteners manufactured by Zechin Industries will be of superior quality resulting from this process.

Many Cold Heading Advantages

Cold Heading can provide significant material savings because of reduced scrap in manufacturing versus machining. Bolts coming off a cold header are usually complete or net finished with nearly zero scrap. Cold heading can improve bolt performance versus screw machining where grain flow is interrupted. The cold heading process rearranges the grain structure increasing shear strength performance. Also, cold heading of bolts and pins offers a consistent higher quality surface finish which is taken from the smooth condition and dimensions of the dies. This can eliminate secondary finishing. Finally, cold heading features a tight tolerance consistency.
