Genuine Makita 450775-5 — Adjuster Base / Adjuster Plate. Fits Makita cordless stapler/nailer service parts lists such as DST220, DST221 and the BST220 / BST221 series.
This is the molded adjuster plate that locates and secures the depth-adjust mechanism (it works together with the adjuster, lock sleeve, an M4x4 pan-head screw and a 4 mm locating pin) so the magazine and feed align for correct staple/nail depth.
Listed in Makita parts breakdowns as the ADJUSTER BASE / ADJUSTER PLATE, the 450775-5 is the original Makita replacement to restore proper depth adjustment and smooth feeding — a small, inexpensive part that directly fixes loose or worn base adjustment problems. This is one of the common power tool parts shown in the service diagrams for those models.
