ROUND PIN TORX Bolts
ROUND PIN TORX bolts create a secure connection between crank and bottom bracket. They feature a round-head design on the outside and a TORX T40 interface with pin on the inside. This design delivers controlled and repeatable tightening during assembly.
The integrated pin increases resistance to tampering, making the bolts well suited to rental and shared bikes. Thread-lock help reduce loosening under repeated load, while the M8x1 interface fits cranksets designed for this standard.
Key Benefits at a Glance
- Controlled Assembly: The round-head exterior and TORX T40 interface with pin allow precise, repeatable tightening during assembly.
- Tamper-Resistant Design: The integrated pin prevents unauthorized removal, ideal for rental and shared bikes.
- Thread-lock Fastening: Thread-lock reduces the risk of loosening under vibration and repeated load.
This helps maintain a secure crank connection over time. - Surface Protection: The ZN-FE coating protects the bolt against corrosion caused by water, dirt and cleaning processes.
- Standardized Sizing: M8x1 thread size and strength class 10.9 fit cranksets designed for this interface.
