Magnetic and locking phenomenon of stainless steel fasteners

Stainless steel fasteners locking is a common defective phenomenon, how do we avoid this defect? This is a lot of people in the use of stainless steel fasteners want to solve the problem, the Chinese standard parts network based on the summary of experience to understand that stainless steel screws in the use of the process of using the process of using, need to pay attention to a number of things that can be avoided stainless steel in the use of the process of locking phenomenon.

Stainless steel fasteners to pay attention to six points, to avoid the phenomenon of locking.

1, use before confirming the mechanical properties of the product to meet the use of demand, such as the tensile strength of the screws and nuts to ensure the load. The length of the screw to choose the appropriate, in order to tighten the exposed nut after 1-2 tooth spacing prevail.

2, before use to see whether the threads are rough, whether there are iron filings between the threads or dirt, these things often guide to locking.

3, before use can be given to fasteners to do lubrication, it is recommended that the use of butter, molybdenum disulfide, mica, graphite or talcum powder to do lubrication, the general use of wax impregnation to do lubrication to prevent locking.

4, screwed into the speed and power to be appropriate, not too fast and too big, as far as possible to use torque spanners or socket wrenches, avoid the use of activity spanners or electric wrenches. Too fast will make the temperature rise rapidly and guide to locking.

5, the direction of force, the nut must be screwed perpendicular to the axis of the screw.

6, the use of washers can effectively prevent the problem of locking too tight.
