*For sheet metals, Class B Tolerance stipulated in JIS B 0408, General dimensional tolerances for parts formed
by press working from sheet metal is used.:
[ ! ]2.Burr height 0.1 or less
[ ! ]3.In case of the thin plates, the tap ridges may be crushed, so please be careful when tightening.
[ ! ]4.When changing to a specification without holes, anodizing with T4 or more may cause a hang hole to be formed as shown in the figure below.

[ ! ]5.Slotted holes may be shaped as shown below depending on dimensions.
(The function as a mounting hole is not affected.)

[ ! ]6.There are machining limits for thickness between hole and hole or between hole and end face. (Example: "b" on the drawing below)
