Cause And Solution Of Fastener Slip

One of the most important things about fastener fastening requirements is not to slip, but the fastener slip is a more common problem. As a professional fastener supplier, Xinchi Fastener Company has more than 10 years of experience in the fastener field, we will give a detailed introduction to this problem, and list the common bolt slip phenomenon and the solution.

Why do fasteners slip?

The cause of the screw slip may be the material of the screw itself. When the screw material is not good, it will produce a lot of impurities, not pure. It may also be because the customer’s product itself is relatively hard (such as an iron plate). We need to find out the reason, so as to solve the problem accordingly and eliminate the sliding teeth of self-tapping screws in the use of products. Screws usually slip because of the following six reasons:

1. The length of the screw is not enough to bear the corresponding torque.
2. The strength and hardness of the screws are not enough, and the material technology and other quality reasons are not good, resulting in slip.
3. Screw force exceeds the standard load of the screw, resulting in slip.
4. Threaded holes or threaded screws are not standard, and the combination between each other is not close enough.
5. If the screw itself is not more than the screw gauge, it will also cause the consequences of slipping.
6. The outer diameter of the thread is small. If the normal machine uses normal threads, the screws with the small outer diameters of the teeth will definitely slip.

Note: There is also a small problem, which is that many manufacturers in order to avoid the screw slipping state, usually will hardened screws. But some screws will also appear the problem of slipping after hardening. This is mainly because some manufacturers do not control the hardness of screws when hardening them. The hardness index of screw hardening should be 480HV~550HV. Therefore, when hardening screws, the hardness should be reasonably controlled within this range.

How to solve the fastener slip problem?

For the fastener slip problem, Xinchi Fastener Company shares the following solutions.

1. Put something on the screw head (such as double-sided tape, or non-woven fabric). If you really can’t, you can use paper. This will increase the friction!
2. Inject a small amount of 502 glue into the screw hole, and then screw the screw in. After the glue sets, unscrew the screw with needle-nose pliers. The glue can be completely hardened.
3. If the screw cap is exposed, use pliers to tighten the screw cap and then remove the screw. You can also cut off the screw cap and disassemble the casing before processing.
