- All‑in‑One 285PCS 7‑Size Metric M3‑M12 Starlock Push‑On Washer Assortment:This kit contains total 285pcs internal tooth starlock retaining rings (also named push‑on washers / external speed clips) covering 7 common metric shaft sizes: M3 ID3×OD9mm (50pcs), M4 ID4×OD12mm (50pcs), M5 ID5×OD14mm (50pcs), M6 ID6×OD16mm (40pcs), M8 ID8×OD18mm (40pcs), M10 ID10×OD20mm (30pcs), M12 ID12×OD25mm (25pcs). These lock washers firmly grip unhardened soft shafts for reliable axial fixation, widely used on bearings, mechanical equipment and industrial shock absorption assemblies
- High Elastic 65Mn Spring Steel with Black Oxide Coating:All starlock washers are made of 65Mn spring steel with excellent rebound and clamping force. Uniform black oxide surface treatment provides moderate anti‑rust performance under dry working conditions, effectively avoiding oxidation for long‑term indoor machinery use
- Internal Serrated Tooth Interference Lock Structure:Built‑in sharp internal serrated teeth bite into the outer surface of soft shafts to form stable interference fit. The self‑locking structure prevents axial sliding and falling off during equipment vibration; slight surface scratches on soft shafts are normal due to tooth clamping
- Easy One‑Step Push‑On Installation:No complicated installation tools required. Simply push the starlock washer onto the matching metric shaft to complete locking and positioning. Greatly improves assembly efficiency for mass production, equipment maintenance and DIY mechanical repair
- Compact See‑Through Compartmentalized Plastic Storage Organizer:Equipped with divided transparent plastic storage case, each shaft size push‑on ring stored in independent separated compartment for quick identification. Lightweight mini box easy to carry to industrial workshops, machinery repair stations and factory assembly lines
