What's grooved(dowel) pins?

grooved pins are press-fit fasteners that combine superior holding power, unparalleled vibration and shock resistance, and easy installation. Each solid cylindrical pin features three longitudinal grooves that have been pressed in to expand the pin’s original diameter in a precisely controlled way. This creates a strong spring mechanism.

dowel pins are solid metal cylindrical fasteners that are used in a wide range of applications. Also known as parallel pins, dowel pins are used to retain parts in a fixed position, maintain alignment between different parts, or to join different components together.

how grooved pins work?

When pressed into a hole the size of the grooved pins original diameter, the hole compresses the expanded pin and creates a forceful hold. This unique locking action is cre ated without permanent deformation of either the pin or base material.

Advantages of grooved pins

Withstand severe shock/vibration, even with axial displacement. Solid construction stronger than spring pins. Different groove types for a wide range of applications, require only a straight drilled or molded hole,reduce assembly steps. driven with hammer, air cylinder or hydraulic press. easy installation and quick assembly, removable and reusable

all stainless and brass dowels are generally non-magnetic and corrosion resistant, however, they are not very hard and can be bent or dented easily. hardened ground Alloy Steel Dowel Pins do not bend, dent, or break very easily because they are case hardened to Rockwell HRC 60 and have a core hardness from HRC 58-65..

alloy dowel pins are excellent for applications where high strength is required. though these pins are not corrosion resistant they can be coated with a black oxide finish to help reduce their tendency to rust.
