Features：

Slotted Spring Pin：Slotted Spring Pin is a hollow, cylindrical pin with a longitudinal slot running along its length. It is designed to be compressed during installation and expand within the hole, creating a secure, self-retaining fit. Slotted spring pins are commonly used in mechanical assemblies where a strong yet flexible connection is required.
Toothed Lock Washer：As specified in JIS B 1255, is a type of washer with multiple teeth or serrations around its edge. These teeth help prevent loosening of a fastener by biting into the mating surfaces, creating a mechanical lock that resists rotation due to vibration, torque, or external forces.

MK SPRING offers both metric and imperial sizes, complying with JIS, DIN, and ANSI industrial standards.
