Original Makita Tension Spring — Part No. 231854-6. This is the genuine Makita "Tension Spring 3" used in the magazine/driver assembly of Makita cordless crown staplers: and is supplied as a single replacement spring.
What it does: a small helical tension spring that provides return/tension for the pusher/driver inside the magazine/sub‑magazine area (it sits adjacent to the pusher and sub‑magazine components in the parts diagram). It’s intended as a direct fit replacement for the spring in that assembly.
Example models this part fits (representative): DST221 (including DST221Z/F/RFE/RMJ variants), BST221, and the DST220 / BST220 series — the same spring is used in Makita’s 18V LXT crown stapler in various market designations.
Notes for use: supplied as one piece (quantity 1 in the parts list) and listed in Makita parts catalogs as TENSION SPRING 3 (Part No. 231854-6), so it’s ready to replace a worn or broken spring in the stapler’s magazine/pusher assembly.
