Genuine Bosch compression spring (part number 1609B00253) — a direct-fit replacement coil spring used in the spring/return assemblies of Bosch GCM 12 series mitre/slide saws.

Fits multiple GCM 12 variants — examples include Bosch GCM 12 GDL (type numbers such as 3 601 M23 660 / 3601M236G0), GCM 12 GDL 230 V variants and several other GCM 12 model revisions; check your saw’s 10‑digit type number against the part to confirm fit.

Supplied as the single compression spring specified in the parts diagram (listed as the part for position 77 on the GCM 12 exploded view); it installs where the original coil provides return/tension for the saw’s mechanism and seats directly into the factory spring pocket.

Simple, ready-to-install replacement — if your saw’s spring is worn or broken this genuine Bosch spring restores the original spring action without modification.
