Locating Pins Small Head, Tapered, Tapped (Part Numbers)

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 small head, tapered, tapped type is easy to assemble and disassemble, thus improving maintainability.

Product Features
Usage outline of large head, tapered, press fit, standard locating pins Locating PinsFeature 1: Standard type with tapered lead-in part. Tapped mounting, tolerance of press-fit part: g7.
Feature 2: The head is available in round and diamond types. The freely specified type is rich in specifications.
Feature 3: Optional material: iron (alloy tool steel or bearing steel); austenitic stainless steel, martensitic stainless steel, suitable for positioning of various workpieces.
Feature 4: Hard chrome plated surface, effectively ensuring surface hardness and antirust.
Precautions
①Dimensional tolerance and fit parameter table For details, click Dimensional Tolerance Fit Table
②Reference table for common dimensions without indicated tolerance (medium accuracy m) For details, click Table of Dimensions Without Indicated Tolerance
③Reference value for thread installation torque The tightening torque (reference value) is the strength class (8.8) in the technical data Torque Reference Table, and the tightening state lasts for more than 24 hours. Not applicable when using locking agents or spring washers.
Example of Use
Example of Use for Locating PinsExample 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.
