The Upper and Lower Thread Guide Bolts are precision spare parts imported for high-speed nylon zipper
forming machines. These bolts securely hold the upper and lower
thread guides in place, ensuring proper alignment and smooth thread
feeding during the zipper forming process. Made from high-strength
steel, they provide excellent durability, stability, and long
service life under continuous high-speed operation, contributing to
consistent product quality and reliable machine performance in
industrial zipper production.
