Grind King Rocketbolts Hardware | 1" Space-Age Design. No More Loose Trucks. The Grind King Rocketbolts Hardware | 1" is a mounting hardware set built to solve one of skating's most common frustrations — bolts that work loose over time and chew out your baseplates. Featuring a unique star-shaped head and vertical fins that lock straight into the deck, Rocketbolts stay tighter for longer and make truck removal easy when it's time to swap parts. Unlike standard Phillips or Allen head hardware, Rocketbolts use a self-locking design: the bolt taps into your deck and tightens from the bottom via the nut, essentially pulling itself flush. The flat, non-countersunk head helps prevent over-tightening, while the fin-locked shaft eliminates wobble and protects your deck from long-term damage — all installable with just one tool.
