Caution

Product Description

Product Overview

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, tapered, threaded, hex socket type can be installed by tightening threads and has a hex socket that can stop the rotation of the head, thus facilitating the installation of nuts.

Dimensional Drawing

Martensitic stainless steel products have an identification groove on D part.

When M<D, the incomplete threaded section (thread pitch×2) is included in M×1.5.

When the M dimension is not specified, the production is based on D = M.

Material No.	Material	Surface Treatment	Hardness	Type	Shape Code
①	Alloy tool steel or bearing steel	-	Quenching hardness 60～63HRC	E-FPNS	A(Round) D(Diamond)
②	Alloy tool steel or bearing steel	Hard Chrome Plated	Quenching hardness 50～55HRC	E-GFPNS
③	Alloy tool steel or bearing steel	-	-	E-BFPNS
④	Austenitic stainless steel	-	-	E-SFPNS
⑤	Austenitic stainless steel	Hard Chrome Plated	Plating hardness 750HV～	E-HFPNS

③Reference value for thread installation torque The tightening torque (reference value) is the strength class (8.8) in the technical data

here, and the tightening state lasts for more than 24 hours. Not applicable when using locking agents or spring washers.

Example of Use

Example introduction: Round and diamond types combined for positioning
①The combination of round and diamond types in the fixture enables more accurate positioning in A direction and reduction of the mating hole pitch error in B direction.
②Of the 2 locating pins, the cylindrical shape is taken as reference for 1 locating pin, and the cut-flat position on the round shape (diamond type) in the direction of the center distance of the two holes is taken as reference for the other, which enables mounting/dismounting operations and ensures positioning accuracy.
③Taking advantage of the different heights of the 2 locating pins, insert the tall pin for pre-positioning and then the short pin for precise positioning.
