What is the tolerance range of precision screws?
Screw (English a screw) refers to the parts used in construction machinery. It is a kind of threaded parts with sharp ends such as nails, small cylindrical or conical metal rods, with grooved or dimpled heads, and used alone. . The detection of the screw should start from the wire of the screw. The quality of the precision screw is directly related to the wire that produces the screw. A good screw wire will open the screws more beautifully. What screw head burst, what thread is bad. Good screw wires generally do not find this situation.
Stainless steel usually refers to steel that has the ability to resist corrosion by air, water, acid, alkali salt or other medium. Depending on the alloy composition, the focus is on rust resistance and acid resistance. Although some steels are rust-resistant, they are not necessarily acid-resistant, and acid-resistant steels are usually rust-resistant. Austenitic stainless steel is mainly used in the production of fasteners. In people's daily life, the stainless steel often referred to is also austenitic stainless steel. The stainless steel fasteners we use are mainly made of austenitic 302, 304, 316 and low nickel 201 as raw materials.
The circlip extrusion and positioning mechanism includes a vertically installed circlip sleeve rod and a linear module controlled by a positioning motor; a plurality of circlips to be installed are sleeved on the surface of the circlip sleeve rod; the surface of the linear module can be Mobile installation quick clamp; the clamping mouth of the quick clamp is a tight top plate; the tight top plate is in contact with the upper circlip and moves up and down with the up and down movement of the circlip sleeve;
The t-bolt can be directly put into the groove of the aluminum profile. It can be automatically positioned and locked during the installation process. It is often used in conjunction with the flange nut. profiles to choose from. T-bolts are movable anchor bolts. Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread) that needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. There are hexagonal head, round head, square head, countersunk head and so on. Among them, the hexagonal head is commonly used. Generally, the countersunk head is used in places where the surface is required to be smooth without protrusions, because the countersunk head can be screwed into the part. Round heads can also be screwed into parts. The tightening force of the square head can be larger, but the size is large.
