Bosch 3604616002 — Compression (pressure) spring — genuine Bosch replacement
Restore the original spring tension in a worn Bosch power tool with this genuine Bosch compression spring, part number 3604616002 (alternate notation 3 604 616 002). It’s the small steel compression/retention spring used inside the tool’s mechanical assembly to provide return force and reliable component seating — the kind of part that fails when a trigger, chuck, or internal retainer stops returning or holding properly.
