Genuine Bosch blade bolt — part number 1619X00935 — a direct replacement fastening bolt that secures the saw blade to the arbor on compatible Bosch / Skil circular saws. It’s the hex-head blade bolt used together with the inner and outer blade washers to clamp the blade firmly for safe cutting.

Fits a range of older Bosch and Skil circular-saw models : Bosch CS10 / CS20 and 1655 , 1656, 1658 series saws, plus GKS 6 and GKS 7 . plus serval Skil models listed for the same Blade bolt. Use this when your saw is missing or has a damaged blade bolt and the washer stack that holds the blade in place.

Notes for installation: these saw models commonly use a 5/8" arbor (≈15.9 mm) and standard 7-1/4" blades (≈184 mm), so this bolt is intended for those blade/arborets and the matching washer pair shown in the parts breakdown. Confirm your saw’s 10 digit type number to confirm fit.

If your saw’s blade-retaining bolt is rounded, stripped, or missing, this original Bosch blade bolt restores the correct clamping fit so you can reinstall a blade and get back to work.
