The flat pad in the combination screw needs to be worn on the front side.

As we all know, in combination screw, if it is three combination screw, it is generally disk head screw, or external hexagonal screw, with a cushion in a flat cushion combination of three components. But what specific requirements are there in the elastic pad? Next, we will briefly introduce the specific requirements for the flat mat in the combined screw.

In fact, there is no specific requirement for flat pads in the combination screws. Only the flat pad in the combined screw needs to be worn on the front. The front mattress looks better. But if the requirements are not very high, there is no need to separate the front and back of the flat pad in the combined screw. Whatever is positive and negative can be done. But it's best if you can wear the front. Prevent customers from having different requirements for flat mats.

For different reasons, customers may cause the screw to break directly. For example, the problem of overexertion. So how much force does it take to assemble the screw?

Generally, the screw used by our customers is 4.8 grade in strength and hardness. When assembling, we require customers to tighten the screw, preferably not more than 14 kilograms of force. The screw is too strong. It will exceed the force on the screw itself. In this way, it is easy to directly lead to screw breakage, slippery teeth and other undesirable phenomena.
