Zinc Plating Countersunk Head Screw Details
Choose the right product
1. Before using the screws, confirm whether the mechanical properties of the product can meet the requirements of use, such as the tensile strength of the screw and the guaranteed load of the nut. The length of the screw should be properly selected to tighten the nut and expose the nut 1-2 threads.
2. Check if the screw thread is rough before use and if there are iron filings or dirt between the threads, since these things often lead to locking.
3. Lubricate the fasteners before use. It is recommended to use butter, molybdenum disulfide, mica, graphite or talc for lubrication. Generally, it is treated with dipping wax to prevent lubrication.
Zinc Plating Countersunk Head Screw Application
Pay attention to the method of use when using the screw fasteners.
1. The speed of the screwing should be appropriate. Do not use too fast or too much. Use a torque wrench or a socket wrench as much as possible, and avoid using an adjustable wrench or an electric wrench. Too fast will cause the temperature to rise rapidly and cause lockup.
2. The direction of the force applied, the nut must be screwed perpendicular to the axis of the screw.
3. The use of gaskets can effectively prevent the problem of over-tightening.
