TRAMPA's M4 x 40mm Socket Capped Bolt is made using A4 Marine Grade Stainless Steel. This very special Bolt is specifically made for TRAMPA & is used to assemble the TRAMPA SUPERSTAR HUBS. The socket capped head of the Bolt screws neatly though the Spokes & into the fixing point in the Rim of the SUPERSTAR HUB eventually screwing into the M4 nut on the other side easly.
Using Marine Grade Stainless Steel, means these Bolts will never rust on you! They can cope with the most harsh of weather conditions & they laugh in the face of sandy/salty beaches or muddy freeride tracks, which do turn other manufacturers Nuts & Bolts into corrosive rusting wrecks! As well as being Non Corrosive all of the TRAMPA Bolts are diped in BLUE THREAD LOCKING PASTE to ensure an extra strong secure fix between the Nut & the Bolt.
