M 4x20 MM

Genuine Bosch 2914501021 — washer-and-screw assembly designed to replace the original captive screw/washer fastening used on Bosch jigsaws and related tools.

Technical detail: captive combination screw with integrated washer, size M4 × 20 mm (metric).

Common fits (examples): GST125-1AELB, GST2000, GST60 (GST60PB / GST60PBE), GST85PB, plus Bosch model's 1581 and 1587 (1587AVS / 1587VS / 1587DVS) and other GST-series jigsaws — cross refence with the 10 digit product code from the side of the machine to confirm fit.

Why buy this one: it’s the original Bosch washer-and-screw assembly specified in parts lists for those jigsaw models, so it installs cleanly where a retained washer and short M4 screw are required and saves you from modifying the tool’s fastening points.

This small, metric replacement is a handy addition to your power tool parts stash when you need a direct fit for Bosch jigsaw hardware.
