Using this Topeak Allen bit set is easy. First, choose the right bit for the job. The color - coded bits make it simple to pick the correct one. Insert the bit into your compatible ratchet or torque wrench. Thanks to the 30mm bit length, you can reach tight bolt spots without any hassle. When you're done, use the knurled part to easily remove the bit from the organizer. As for maintenance, keep the bits clean after each use. You can use a dry cloth to wipe off any dirt or debris. Store the set in a dry place to prevent rust. Avoid using the bits with excessive force as the S2 hardened steel, while strong, can still be damaged. If you notice any signs of wear, it might be time to replace the bit.
