This non-bearing truck tuning is the strongest tuning there is. These screws are made of a very strong stainless steel and should not strip or break. They have a socket head which fits a standard sized allen key. They thread perfectly into any set of TechDeck trucks and fit through any wheel without bearings. There is no need for an adhesive. Just thread in and go. Non-Bearing Tuning comes in a set of 4 screws for only $3.00.
