The Grooved Pins are parallel pins with three equi-spaced longitudinal grooves. They are rolled or pressed into the cylindrical body to deform the pin stock outward within controlled limits. When this pin is forced into a drilled hole of proper diameter, a locking fit is obtained. Only a straight drilling hole is required and no reaming is needed. A few of them are illustrated above.

When pressed into a hole the size of the Groov-Pin’s original diameter, the hole compresses the expanded pin and creates a forceful hold. This unique locking action is created without permanent deformation of either the pin or base material.
|Tolerance of Groove 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,Can be hopper-fed for automatic installation,Easy installation and quick assembly,Removable and reusable.
Grooved pins are manufactured from stainless steel material etc. our manufacturing range for grooved pins is from 0.2 to 16 mm in diameter and 1 to 200 mm in length.cylindrical (dowel) or parallel pins are used either to retain parts in a fixed position or to preserve alignment.
Internal threaded cylindrical (dowel) pin are for easy extraction, from blind holes. hardened pins are manufactured from case hardened alloy steel or as per buyers requirement. air vent may be provided.

Taper Pins are preferred for parts which have to be taken apart frequently and when driving out the Cylindrical Pins, would tend to wear the holes and also to very accurate constructed tools and gauges which have to be kept in absolute alignment.
External & Internal Threaded Taper Pins are used for extraction of the pins more conveniently.
