We successfully apply for 'K' or '王' fastener manufacturing logo

According to the requirements of the state, all factories should make the performance rating code and the manufacturer (or distributor) identification mark on the fastener products. Otherwise, should be based on substandard products. (except for the exception of the legal system below M5)
On every fastener product sold, we will make our own identification mark according to the standard requirements, showing that we dare to be responsible for the quality of our products forever, and also reflect the integrity of our company.

Our headline is "K" or "王". One of the two characters on the head of the screw is our product (except for anti explosion). Our company will guarantee the quality of the product.
