m4 stainless steel machine screws, pay attention to this place when placing an order

When the person who knows the screw is not very deep, the screw that may be purchased is not what he wants. Or when the order was placed, there was a detail that was not noticed, and the m4 stainless steel machine screws that were produced could not be assembled. Why?

When the wire screw is assembled, the assembled product has a hole on it, and the internal thread is also punched in so that the screw can be screwed in. But when this happens, it can’t be screwed in. The pitch of the internal thread is different from the pitch of the m4 stainless steel machine screws.

If the pitch of the internal thread is 0.5mm, and the pitch of the m4 stainless steel machine screws is 0.7mm, then the screw will not be screwed into the product during assembly. Therefore, when the customer places an order, it is necessary to figure out the details of the assembled product, otherwise, the purchased screws can not be used. In this case, the cost of the screw is invisible.
