A self-extracting crank bolt has a built-in mechanism that allows the crank arm to be pushed off the bottom bracket spindle simply by tightening the bolt itself. This eliminates the need for a separate crank puller tool.
No, these bolts are specifically designed for TA Specialties square axle bottom brackets and will not fit other types or brands.
The thread size is M8x20mm.
No, these bolts are self-extracting, meaning you only need the appropriate hex key to tighten them and initiate the crank removal process.
The brass washers are included to provide a smooth surface and protect the crank arm from damage during tightening and the self-extraction process.
Each set of two bolts weighs approximately 18 grams.
These bolts are designed for TA Specialties bottom brackets. While they might fit the crank arm threads, compatibility with the bottom bracket interface is crucial for proper function and safety.
Ensure the self-extracting bolt is threaded in far enough to engage the bottom bracket spindle. Sometimes a gentle tap on the end of the bolt with a rubber mallet can help initiate movement. Confirm that the bolt is not fully tightened against the crank arm before attempting extraction.
Check for any debris or cross-threading on both the bolt and the bottom bracket spindle. Clean the threads thoroughly. Ensure you are using the correct M8x20mm bolt and not a different size.
While the dust cap is integrated, if damage occurs, replacement bolts may be necessary. Clean the area thoroughly to prevent ingress of dirt into the bottom bracket.
