The hex nut is one of the common nuts. It is used in conjunction with bolts and screws to connect and fasten parts. It has internal threads and is used in conjunction with the screw to transmit motion or power. Among them, type 1 hex nuts are the most widely used. C-level nuts are used for machines, equipment or structures with rough surfaces and low precision requirements; A-level and B-level nuts are used for smoother surfaces and higher precision requirements. on machinery, equipment or structures. The thickness m of the type 2 hex nut is relatively thick, and it is mostly used in occasions that often need to be assembled and disassembled. The thickness m of the hexagonal thin nut is relatively thin, and it is mostly used in occasions where the surface space of the connected parts is limited.

A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. It is an original part that must be used in all manufacturing machinery. How should the hexagonal nut be processed? The hexagonal nut manufacturer Weifu standard parts simply Let me introduce you to the 8-step method of processing hex nuts.
1. Scribe to find out the center of the hexagon, make a proof punch, draw a check circle or check the frame line.
2. Calculate the diameter of the bottom hole according to the formula D=d–P, select a suitable drill bit to drill the bottom hole (drill the center hole with a small drill bit before drilling the bottom hole) and chamfer on both sides of the bottom hole.
3. Tap the M12 thread in the correct way, and lubricate it when tapping the thread.
4. According to the formula rod d round rod = d-0.13P, check whether the diameter of the blank round rod is qualified.
5. First process the hexagonal head of the bolt, the method is the same as that of the nut.
6. Then set the M12 thread according to the correct method. When threading the thread, it needs to be lubricated, and the thread should be inserted to the end.
7. Nuts and bolts are chamfered and trimmed.
8. Deburring, re-inspection, and finishing of the workpiece.
