It is the trademark of the company

An extra step of lettering will increase the cost of the mold. When the mold explodes, workers need to replace it (usually produced on a multi-station cold heading machine) . This is a sign that the company is responsible for its products! Usually, bolt products with high strength and high requirements will be marked with a header, while other products with lower grades do not have this process

Attention! Regular bolt products will not allow products with incomplete font markings to enter the market. The head markings are clear, complete and rounded.
