The Burton Highback Hardware Mounting Washer replacement. Fits most highback bindings

• Pair with M5 15mm Nut and Bolts for most newer bindings
• Pair with M5 12mm Nut and Bolts for most older bindings

I'd recommend some phillips head bolts as most pocket snowboard repair tools has a phillips head driver so you can give it a tighten on the mountain. Also they are smoother on one side so it won't damage your boots

Some washers as well will go along way and make your bindings last a bit longer

I'd also recommend investing in some locking nust as well with a nylon insert to prevent the nut from backing out while riding
