Avid Titanium M3X8 clutch screw

Avid’s new clutch screw is made from the highest quality 6AL-4V Titanium and is packed with a ton of cool features. The most obvious is the large flange to help keep out any fuel or debris from entering your clutch bearing. The second most obvious feature is that you can use a 5.5mm nut wrench or a 2.5mm Allen wrench to install and remove. Lastly, on the backside, they have added a small recess so the screw will never drag on your bearing seal/shield.
