long hex screws

One time to form a long screw, Mr. Zhu from Tianjin sent a non standard long hex screws to consult whether it can be produced. The specification of this long screw is M5*650 long, and the required strength grade is at least 8.8, and the welding process cannot be used. produce.

Mr. Zhu said that the reason why he has not found a suitable screw manufacturer is mainly because most of the long screw manufacturers use the welding process, and the welding process is easy to break, and the strength level is not up to the requirement. The environment of the screw requires that this long screw needs to have 8.8, and the torque must reach a standard, so Mr. Zhu found many screw manufacturers on the Internet.

It was found that Shenzhen Screw Factory Shi Shi Tong can produce a long hex screws with a strength rating of 12.9, so Mr. Zhu contacted Shi Shi Tong Screw Factory and sent the drawings. Soon, Miss Song, who calculated the price, calculated the price in the past, and Mr. Zhu quickly put the order down. After looking for so long, Mr. Zhu finally found a long hex screws that can be formed at one time, and the product will soon enter the production stage, so Mr. Zhu quickly sent the payment.
