M4 x 10mm Countersunk Head Bolt Marine Grade Stainless Steel

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.

The head of this Bolt is COUNTERSUNK, meaning that when screwed into position it sits flush & neat with the surface its screwed into. Preventing bolts from standing proud eliminates the chance of anything getting "snagged or hung-up" should it get caught on something..

- Connecting the PISTOL GRIP to The WAND

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...
