Extralite's chainring bolts are precision machined from 7075 aluminum, black anodized, and laser etched "Extra Bolt". The nuts are knurled along their inner edges to prevent spinning and aid in achieving proper torque. Extralite's chainring bolts are available in sets of four or five, designed for mountain or road double chainring setups.
A T30 Torx wrench and 6mm hex wrench are required for installation of Extralite chainring bolts.
