If you are working on your moped, you know that reliability starts with the smallest components. This original stud bolt with the dimensions M6x31mm is exactly the right spare part to securely and firmly fasten your cylinder or exhaust. Since it is an original part from Beta, you can rely on a perfect fit and the appropriate material quality that withstands the thermal stresses of the engine.

Why an original part? Especially at the outlet or the cylinder, high temperatures and vibrations occur. A low-quality bolt can seize or, in the worst case, break off. With this original spare part (Beta number 521), you make no compromises. The precise threads ensure that the nuts remain where they belong even after many kilometers.

Tips for installation:

• Cleanliness: Thoroughly clean the internal thread in the cylinder before inserting the new stud bolt.

• Countering: Use two nuts that you screw against each other (counter) to firmly turn the bolt into the housing without damaging the thread.

• Heat protection: A small dab of copper grease or ceramic paste on the thread prevents the bolt or nut from seizing due to heat. This way, everything can be easily loosened in the future.

Care tip: After the first rides following installation, briefly check if the nuts are still tight. Due to heat cycles, the material can settle. A quick check gives you the reassurance for the next trip.
