Caution

Product Description

This is an economy item, The price is cheaper than the MISUMI standard product.

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, tapped type is easy to assemble and disassemble and widely used.

B dimension in ( ) applies to Diamond Shape.

Pins of D dimension with T have one size smaller thread diameter and larger wall thickness. (Actual D dimension is the number without "T".)

L dimension in ( ) applies to Diamond Shape.

Note the strength of under-head part.

②Reference table for common dimensions without indicated tolerance (medium accuracy m) For details, click

Table of Dimensions Without Indicated Tolerance
③Reference value for thread mounting 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 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.
