Locating Pin Small Head, Flat End, DP Tolerance Selectable, Press-Fit Type

The positioning 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 small head flat type with DP tolerance selection offers flexible selection and can meet most customer design requirements.

The D section of martensitic stainless steel or equivalent high-hardness corrosion-resistant steel is equipped with an identification groove.
Austenitic stainless steel may be ground or have no center hole.

The D section of martensitic stainless steel has an identification groove.
Austenitic stainless steel may be ground or have no center hole.
Because it has a center hole, when the P dimension is small, the spherical part is almost invisible.
If there are requirements for rust prevention, give priority to products with hard chrome plating or made of austenitic stainless steel.
