M4 x 25mm Socket Capped Head TORX Bolt ISO 4762 Marine Grade Stainless Steel

TORX Screws are less likely to strip out when compared to a hex screw, because of the way the load is distributed and applied between the tool and the hardware. Because of this load distribution, the height of the head of the bolt can be reduced - making them nice & flush. 

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.

M4 8x8mm Nikel plated Flush fitting Threaded Insert Nut is Screwed into the ORRSOM longboard deck & used for fixing the Underboard Battery Tray to the Deck

This M4 8m x 8mm RAMPA Muffen or Insert nut will allow you to secure M4 Bolts to your deck without the need of using often unsightly or protruding nut on the other side leaving a neat clean smooth finish to your assembly....

We use these M4 RAMPA Nuts to secure the UNDERBOARD Battery Tray to the underside of all of the Electric ORRSOM Boards...

To make the hole to accept the fitting the nut, you will need to measure accurately so first make a pilot hole using a 2/3mm drill bit. Then specifically using a 5mm Steel drill bit, carefully drill the larger sized hole remembering to drill at 90º to the surface. If you do not Drill 90º to the surface your RAMPA Nuts will not fit flush...

Once you have made the 5mm holes, use a 4mm Allen Key to screw the RAMPA nut into the deck. Be careful when screwing in, you need to add a little bit of force to make it bite into the surrounding material, but not too much force as you do not wish to push through anything.... Turning the M4 Allen Key may be tough as when screwing the nut into the deck as it will literally cutting a thread into the surrounding material of the deck as you do...  It may help secure the RAMPA nuts even better if you add a tiny squirt of Glue as you tighten up the last few turns...
