WebThe number of holes and depth may also be specified. Figure 11-4 shows how symbols are used in local callouts for holes. Standard practice recommends specifying the holes as 2 X .250 with the leader line only pointing to one hole. The depth symbol is used in front of the depth value. If the depth is specified as THRU (for through), the hole WebProjected Tolerance Zone. Applies to a hole in which a pin, stud, screw, etc., is to be inserted. It controls the perpendicularity of the hole to the extent of the projection from the hole and as it relates to the mating part clearance. The projected tolerance zone extends above the surface of the part to the functional length of the pin, stud ...
