Locating Pins Small Head, Round Tapered, 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 small head round tapered type can be inserted smoothly and is free of edges at the head, thus preventing damage to the objects being positioned.

①	Alloy tool steel or bearing steel	Hard Chrome Plated Plating thickness: 3μm or more	Quenching hardness 50～55HRC Plating hardness 750HV～	E-GJPRS	TB(Tapped)
②	Austenitic stainless steel	-	-	E-SJPRS
③	Martensitic stainless steel	-	Quenching hardness 50～55HRC	E-CJPRS
④	Alloy tool steel or bearing steel	Buffed	Quenching hardness 60～63HRC	E-MJPRS
⑤	Alloy tool steel or bearing steel	Hard Chrome Plated + Buffed Thickness: 3μm or more	Quenching hardness 60～63HRC Plating hardness 750HV～	E-MGJPRS
⑥	Martensitic stainless steel	Buffed	Quenching hardness 50～55HRC	E-MCJPRS

If there are requirements on rust prevention, give priority to the hard-chrome plated products, products with surface treatment of electroless nickel plating or products made of austenitic stainless steel.
