M4 x 4mm Grub Screw M4 x 4mm Motor Pulley Grub Screw - Connects the Motor Pulley onto the Motor Axle Shaft

Made from A4 Marine Grade Stainless Steel, all of the nuts, bolts & screws used in a TRAMPA board have proven to be up to the challenge of holding everything together. Using Marine Grade Stainless Steel also means these Bolts will never rust on you! They can cope with the harshest of weather conditions & will laugh in the face of sandy/salty beaches or muddy freeride tracks - which can turn other manufacturers’ nuts & bolts into corroded rusting wrecks!

Wherever possible, we dip all our bolts into BLUE THREAD LOCKING PASTE, to ensure an extra strong & secure fix between the nuts & bolts.
