basic information
【Other Features】 <Dog Spike (Round Spike)> ■ Used for N rails (with Witt screws) for turnouts, expansion joints, and fastening sleeper plates for turnout types. ■ Used only for repairs of existing turnouts and expansion joints that utilize Witt screws. <Dog Spike (Square Spike)> ■ Used for N rails (with metric screws) for various turnouts and fastening sleeper plates for expansion joint turnout types. ■ Designed considering the shortcomings of the round spike listed below: - Sleepers are prone to cracking. - When driving the dog spike, it tends to rotate easily, and if the sleeper is corroded, it can easily come out due to the lack of corners. - When driven into floorboards, it is difficult for the crowbar's claw to grip, making it hard to remove. *For more details, please refer to the PDF document or feel free to contact us.
