e.g. a riser screw or any screw available in the handlebar area of the motorbike such as the fixing screws for the handlebar parts, mirrors or instrument controls. Unlike its equivalent Screw M6 it is made of durable die-cast metal.
To attach the Screw Pro motorbike mobile phone holder, the original screw must be removed from the chosen position (e.g. from the riser) and replaced with one of the supplied 6 mm stainless steel screws 40, 50 and 60 mm long to tighten the attachment. Optiline has come up with an 8mm version of Screw Pro in case there are no 6mm screws.
The sphere allows the phone holder to be fully adjustable, allowing its use and display both in vertical and horizontal.
