Original
By certification 
1. Titanium button head bolts made according to standard ISO 7380, DIN 9427 or ASME B18.3. Torx ( T 15 to T 45 ) could be instead of the original hex socket. We always have ISO 7380/DIN 9427 M5 to M8 bolts on our shelves to ship once the order confirmed. The bolts are used in bicycles and motorcycles racing applications due to benefits below:
● Manufactured from ASTM B348 Grade 5 Titanium alloy bars ( 6AL-4V Titanium )
● 45% lighter than steel equivalents, strength and corrosion resistance
● Rolled thread for better fatigue resistance and avoid galling, NOT like cutting thread
● Shiny polished finish that look better than original
● More colours finish available, contact us
