Original Bosch spring washer — part no. 1619P04820 — a small stamped spring/retaining washer used in Bosch reciprocating saw assemblies to hold covers and related fasteners under vibration.

This genuine Bosch washer is listed in exploded parts diagrams and fit lists for reciprocating saw models including GSA 1100 E, GSA 1300 PCE and the PSA 700 E, where it secures the gear/cover area and prevents fasteners from working loose.

Sold individually and commonly shown as “spring washer” or “washer” in Bosch power tool parts breakdowns (also formatted as 1 619 P04 820), it’s a simple replacement that restores proper retention of the gear cover/holder so your saw runs safely and reliably.

If you’re repairing a reciprocating saw and only need the fastening component, this genuine Bosch part is the specific spring washer to match the diagrams used by Bosch Power Tools for those models — a small part that prevents much bigger problems.

Note: this item is shown at power tool parts for the models listed above.
