Just make sure they are not too long for your board.

Depends
The old Chinook blocks used a 10G screw as the guys said.

The ones on most boards now (ie: made at Cobra factory) have a larger hole and use a 6mm OD Plastite screw (which you will not get anywhere bar a WS / KS shop). Though nay kiteboards are still using the old school syste

Best to measure them.
Just use a drill bit to size it.


If the hole is about 3.5mm is what they guys said above.

4mm or smidge bigger (I think 4.2mm in reality) its a M6 Plastite.

Big differences

Don't fark up your board from wrong info. Your inserts will be a certain diameter and depth, also imp or metric , pretty easy to go to your local hardware and select correct fitting, ensure its marine grade stainless , personally I'd go Alan key or star key head, don't forget your strap as that'll affect length of fixing

It is beyond your capability mate, you are too old learn anything new. Stick to your twin tip and speedo's.

Okay Gramps, just remember the pointy end goes forwards.

spread your legs sweetheart
