High fastening strength! Screws for rails that are resistant to loosening.
The "rail screw nail" is a screw that has been threaded to increase the resistance to pull-out of the nail. Its purpose is the same as that of a dog nail, which is to secure the rail and tie plate. With the widespread use of synthetic sleepers, there are many cases where screws with thinner shaft diameters or smaller head diameters than conventional rail screw nails are manufactured in different shapes depending on the application. Upon receiving the drawings, our company will start with the design of the mold and proceed with manufacturing. 【Features】 ○ Provides a higher fastening force to wood and synthetic sleepers, making it less likely to loosen. ○ Has a high-precision and strong screw section due to the hot rolling method. *In urgent cases, please contact us through our website for technical inquiries.
