*This is for the Original m8 version The original involute didn't have a handle so i can blow my candles out for long periods of time, well it hurt my hands after cranking on a bolt all day so here is a drop in attachment/accessory.leave your original bolt handle as it is (Assuming it is bolt-head on one side and the nut on the other) just slide this over your bolt handle and place either a m8 flat washer(a wide one) or a 608 bearing inside and then 2 m8 nuts all the way down and tighten. I gave the handle enough clearance near its base for you to tighten all the way down without worry. Congratulations now you can blow things all day.
