Can stainless steel machine screws with small tolerance be made?

No matter what product, there will be a certain tolerance range in the production, but different products for the tolerance requirements are not the same. For fasteners, the tolerance is not fixed, because the tolerance required by each customer is different, some customers may be very strict tolerance requirements, such as ±0.05mm, some customers are very loose requirements. So, can we make stainless steel machine screws with small tolerance?

Mr. Gao from Shanghai needs to order a new stainless steel machine screws. The size tolerance of basically every part is required to reach ±0.05mm, and even the tolerance of some places is +0.05/-0.02. The surface of the screw is not allowed to have burr, the tail is required to have chamfer, and the size of the thread is M5*32mm. According to Mr. Gao’s requirement, the cold heading production method cannot be satisfied, and the car processing method must be used for the production.

The tolerance of stainless steel machine screws produced by automobile processing can basically reach ±0.05mm, but the customer has other dimension tolerance requirements of +0.05/-0.02. If this tolerance is to be achieved, a grinder is needed, and the production time will be prolonged in this processing mode, because the ground processing is required.

Mr. Gao said that it doesn’t matter if the production time is longer, he only requires us to produce stainless steel machine screws that meet his requirements, because the assembly place has strict requirements on tolerance, and if the tolerance exceeds the tolerance, the assembly will not be able to go in.
