1. First, remove the sludge on the surface of broken screws and broken ends and bludgeon the center of the section to death. Then, install a 6-8mm diameter drill bit with an electric drill to drill the center bludgeon hole. After the hole is drilled, remove the small bit and replace it with a 16 mm

Now the use of stainless steel for manufacturing fasteners has been very popular, but for stainless steel fasteners, there are four major performance points, which are described as follows:1. High temperature resistance of stainless steel fasteners. Because of the hardness of stainless steel itself

As for fastener products, the following standard conditions must be met during production to ensure the customer's utilization of fastener product quality. What are the standard conditions for fastener products? There are five main types.1, fastener product size standards: specify the basic size of
