Although it purchased it is a general M4 type, it is rusty and is a place where there is a danger of sticking and a minus head is required for removal. Furthermore, durability was also improved by making it made of stainless steel this time.
It is used as a screw to fix the lug of the drum set.

The screw fixing the lug of the drum set is a black painted item made of steel, but if the storage condition is bad, rust will occur immediately. Since all the screws of the used drum set were supposed to be ugly by rust, we decided to exchange it with stainless steel one. The screw that stops the lug of the drum set is the type in which the spring washer and the usual washer are built in beforehand together with the screw, but since it is a device to raise working efficiency, we personally exchange one car If it is, there is no problem even if it falls apart. There are screws of the same size even at home centers etc., but stainless steel is high, and it becomes a considerable amount when it becomes one drum set. Since this product is a built-in spring washer, after purchasing another washer with a larger diameter, it was sufficiently substitutable. It was saved because the price was cheap as well. Because the size of the length is abundant, I think that it can be used for models with different shell thickness.
