Makita 324621-7 Spare Part - ADJUST PIN UC4020A/3520/3530A

Original Makita adjust pin 324621-7 — a hardened steel chain-tension pin designed for the UC-series electric chainsaws. This small but critical component engages the chain-tensioning mechanism to set and hold correct chain tension and guide-bar alignment, helping maintain smooth cutting performance and reduce wear on the bar, sprocket and chain.

Direct-fit replacement for the factory part (listed as 324621-7, replaces old number 226-213-410) and compatible with many Makita electric chainsaws including UC3020A, UC3520A, UC3530A, UC4020A, UC4030A and select BUC models. Durable steel construction with an M5 sizing for correct fit in the tensioner assembly.

Easy to install with basic hand tools — keep this genuine Makita adjust pin on hand for routine service or when the original adjuster shows wear or damage. Restore reliable chain tensioning and get your saw cutting true again.
