Locating Pins Large Head, Round Tapered, Configurable - Tolerance, Taper R Selectable, Tapped

The locating pin is used for the spatial positioning in the directions of X and Y axes, mainly using the workpiece hole as the positioning benchmark or used in conjunction with bushings, in which the large head, round tapered, D and P tolerance, taper R selectable type provides flexible selection and can meet the design requirements of most customers.

Pins of D dimension with T have one size smaller thread diameter and larger wall thickness. (Actual D dimension is the number without "T".)
Note the strength of under-head part. Please confirm pilot hole depth. Holes may go through.
