Wanxi supply grooved pin full length taper groove DIN1471/ISO8744

groove pin Full length taper groove DIN1471 ISO8744

DIN1471, ISO8744 full-length taper grooved pin is characterized by a full-length taper grooved pin with three longitudinal grooves spaced equally on its surface. When the taper grooved pin is drilled into a hole with the same diameter, it shall achieve a close fit.

1、 The full length taper groove positioning principle of grooved pin is shown in ISO8744 below:

Since the groove diameter d2 of the grooved pin is larger than the hole diameter, when the grooved pin is drilled into a hole equal to d1, it closely fits with the hole wall, and is deformed due to extrusion, so that it is stuck in the hole to avoid loosening. This grooved pin is generally disposable.

2、 The diameter of the pin hole shall be equal to the nominal diameter of the grooved pin, and its tolerance zone is H11

3、 Specifications, materials and technical parameters

Specification: d1.5-d12

Carbon steel: natural color, hardness: 125-245 HV30 (ISO 8744)

Stainless steel: A1, hardness: 210-280 HV30 (ISO 8744)

Both ISO8744 and DIN1471 can be made of austenitic stainless steel A1, but the length of each standard is different. Please contact our company for details.

4、 Classification and standard comparison of grooved pins

According to the groove type and appearance, it can be divided into the following categories:

For the full-length taper grooved pin DIN1471 ISO8744, the specifications, dimensions and performance parameters are subject to the actual supply of our company. This article is for reference only.
