Makita 252171-1 Spare Part - SQUARE NUT 4340/SMA400

Original Makita 252171-1 — square nut (fits M5 / 5 mm threaded fasteners). This small, low-profile square nut is a genuine Makita replacement used to secure assemblies on jigsaws and compact saws; it’s lightweight (about 4.5 g) and sized to sit squarely in a machine’s mating slot for a positive, rattle-free hold. It’s exactly the kind of parts for power tools you want when you’re repairing a blade/guide mounting or reassembling a handle or base plate.

Example models this part is listed for include Makita jig saws and saws such as 4340FCT, 4341FCT, 4350FCT, 4351FCT and several BJV and XVJ series models (BJV140Z, BJV180 / BJV180Z / BJV180F, XVJ01Z, XVJ03Z).

Simple to fit and identical in form and fit to the original Makita nut, 252171-1 replaces worn or missing square nuts so your tool reassembles cleanly and functions as intended.
