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

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.
