The Multiquip 02041023531 Tooth Lock Washer 12mm is a genuine OEM replacement designed for the ST-4100 series equipment. As a direct OEM component, it is manufactured to the same specifications as the original hardware, ensuring a consistent and correct installation every time. This washer is sourced directly through Multiquip's authorized parts network and is the exact component called out for ST-4100 applications.
Key Features
- Hardened Tooth Engagement — Serrated locking teeth bite into the mating surface to resist loosening under vibration and load, maintaining fastener integrity throughout operation.
- Genuine OEM Construction — Manufactured to the same material grade and dimensional tolerances as the original 02041023531, so hardware torque values and seating behave exactly as designed.
- Direct Drop-In Hardware — 12mm bore size matches the original fastener stack on ST-4100 assemblies with no reworking or shimming of the joint required.
- ST-4100 Confirmed Fitment — Verified for use on the Multiquip ST-4100, eliminating guesswork when ordering replacement hardware for this machine.
- Protects Fastener Joints — A worn or missing lock washer allows bolts to back out under repeated machine vibration, which can lead to misalignment, component shift, or structural fastener failure.
A tooth lock washer is a hardened fastening component placed between a bolt head or nut and the mating surface. Its serrated teeth compress and grip both surfaces when the fastener is torqued, creating mechanical resistance that prevents the bolt from rotating loose during operation. On equipment like the ST-4100 that generates sustained vibration, lock washers are critical to keeping assemblies tight and secure. When a lock washer is missing, damaged, or flattened from reuse, the fastener joint loses its locking ability and bolts can gradually work free, risking component movement or damage.
