Avid Ringer Aluminium Cap Head Screws
Avid Racing Concepts have released these Ringer Aluminium Cap Screws that are designed to offer the hardcore racer the ability to shave off even more weight than their titanium screws. Machined from 7075-T6 aluminium they have a self-centring 1mm shoulder with a 3mm outside diameter at the head making them ideal for touring car top decks. At 40% lighter than titanium, they save a lot of weight however Avid do caution that if the screw needs to be cranked down, then don’t use these as aluminium screws are not strong.
