Stainless steel fastener bolts have the advantages of strong and durable, good corrosion resistance, etc., and are very popular in many industries. But in daily life, stainless steel bolts appear locked problem, what is the reason? How should we prevent the stainless steel bolts locking up? Aozhan hardware fasteners to give you the answer.
The stainless steel plate is too soft, flexible and has a strong plasticity for cold drawing. The bolt surface is damaged when it will cause a very thin layer of oxide (chromium oxide) to give maintenance to avoid further rusting. In the torsion link, the fastener bolt teeth between some pressure for heat, will damage the chromium oxide layer, making the metal teeth directly block or shear, and then staining, resulting in locking, which is the main reason for locking. Lock-up of fastener bolts is usually an instantaneous event, so we need to better understand fastener bolts to prevent lock-ups from happening.
How to prevent the problem of stainless steel bolt locking?
A. Choose the right bolt products.
1. Reasonable choice of the correct length and specifications of the screw model, to tighten to reveal the nut 1-2 tooth pitch shall prevail.
2. Confirm the tensile strength of the screw and the safety load of the nut before use.
B. Reduce frictional resistance.
1. Screw tooth surface cleaning, screw tooth surface if the foreign body often causes locking.
2. It is recommended that the surface is coated with water wax or added lubricant (such as butter, 40 # oil).
C. Pay attention to the operation steps when using.
1. The thread must be screwed perpendicular to the axis of the thread, do not tilt.
2. The speed and force of screwing should be moderate, the force must be even, and the tightening torque should not exceed the safe torque.
3. Use torque wrenches or sleeve wrenches as much as possible, avoid using movable wrenches or electric wrenches, as the speed of movable wrenches or electric wrenches will make the temperature rise rapidly and locking problems will easily occur.
4. Avoid using in high temperature condition.
D. It is better to use Aozhan wax anti-locking nuts or oil anti-locking nuts.
E. Using washers can effectively prevent the problem of locking on too tight.
The above is a simple explanation of how to prevent stainless steel bolt locking method by Aozhan, I hope it will be helpful to you.
