HEX TORX Bolts
HEX TORX bolts create a secure connection between crank and bottom bracket. They feature a dual interface with external hex and internal Torx T40 for controlled and repeatable tightening during assembly.
HEX TORX bolts are available in multiple surface finishes and with optional thread-lock. This lets you choose the right bolt depending on your corrosion protection and locking needs. They fit cranksets with M8x1 interfaces to hold the crank securely in place.
Key Benefits at a Glance
