The Threaded Cylindrical Pin manufacturer tells you that the cylindrical pin is fixed in the pin hole by a small amount of interference, so it cannot be assembled and disassembled frequently, otherwise it will reduce the positioning accuracy and the reliability of the connection.

Cylindrical pins are generally fixed in the holes by a small amount of interference to fix parts, transmit power (can bear a small load) or serve as positioning elements.
When positioning with cylindrical pins, in order to ensure the quality of the connection, the two holes of the connected parts should be drilled and reamed at the same time. The size, shape and surface roughness of the pin hole are required to be high, and the surface roughness value of the hole wall should be Ra1.6. Threaded Cylindrical Pin manufacturers tell you that when the positioning requirements are not too high, CNC machine tools can also be used to meet certain accuracy.
When assembling the cylindrical pin, apply oil on the surface of the pin and use a copper rod to lightly drive the pin hole.
Threaded Cylindrical Pin manufacturers tell you that since the cylindrical pin holes are reamed, repeated assembly and disassembly will reduce the positioning accuracy and connection tightening. Therefore, the cylindrical pin should not be assembled and disassembled multiple times, otherwise the positioning accuracy and connection tightening will be reduced.
Threaded Cylindrical Pin manufacturers tell you that cylindrical pins usually do not bear load or a small load when positioning, and the number is not less than 2, which are distributed in the symmetrical direction of the overall structure of the connected parts. The farther the distance, the better. The length inside the piece is about 1~2 times of the small diameter.
