Where to buy prop bolts?

Recommended Posts

He he he, no, you're right about the measurements! :mrgreen:

Thanks for the offer. I'll have a look on the internet with the revised and definitely more accurate measurements!

Do they have to be any kind of special type of bolts?

Or would these be suitable? http://www.ebay.co.uk/itm/like/25125817 ... 101&ff19=0

Don't think so, you need 12.9 high tensile grade

Hi Tommy just to think how thick Propeller Mounting Plate/Spacer you have ,if just 2mm then you need Stainless steel allen key bolts M6x50mm if your plate is thicker 4mm then you need M6x55mm,but I think you need M6x50mm,not 11 or 12cm long :shock: what for? 3 weeks ago I received from dtpropeller 130cm dia prop for my racket, its 4 mm thicker hub than standard is,but what the power :o no compare to any other excluding "E-propeller"but this is different story
