What are the different types of pins?
At Gardette, we manufacture and stock different mechanical pins, with some of the main kinds being:
This pin is suitable for run-of-the-mill fastening applications, often used for positioning or hold purposes. It can be found in many mechanical component assemblies, e.g. for positioning engine or gearbox components.
DIN 7 and ISO 2338 standards define the tolerance class H11 for the diameter. However, we also produce this pin at lower tolerances: H8 or M6.
Unlike other dowel pins, the DIN 6325 - ISO 8734 ground pin is made of steel that has been hardened then ground, giving it very tight tolerances: M6 or H6.
These high-precision pins allow for micron-sized accuracy when fitting the pin in its housing. They are widely used in sectors such as aeronautics and industrial electronics, for aligning electronic systems in fuse boxes.
Suitable for blind holes, this pin has an air release flat to prevent air compression, eliminating the risk of damaging the hole and ensuring that the pin is not rejected by its housing. Pins with internal threads are ground with M6, H8 or H11 tolerance, depending on your particular requirements. This makes them ideal for use in mechanical engineering.
As well as this, the pin's internal thread means it is fully extractable with a pin extractor tool, making for easy disassembly.
Taper pins made to DIN 1B - ISO 2339 standards are solid pins with rounded ends and a tapered body (taper angle 1:50). Made of high-carbon or stainless steel, they allow parts to be fixed or locked via friction.
The internally threaded version of the standard taper pin. The internal thread allows for easier removal of the pin. These pins are commonly used in assemblies that require frequent dismantling.
This model has a solid tapered base, with a threaded part of equivalent diameter at the pin's tip. This pin offers additional fixing power.
Grooved pins, as the name suggests, are equipped with grooves along their length which allow the pin to inflect and compress in the hole. They ensure a perfect fit and excellent hold.
DIN 1481 - ISO 8752 spring pins, also known as roll pins or Mécanindus pins, have the ability to compress when inserted, before then going back to their initial diameter. This pin's high elasticity allows it to remain firmly in place without the need for particularly high precision during assembly.
The DIN 94 split pin AKA cotter pin is split across its length, with two tines that are bent during installation. It is made of low-carbon or stainless steel. These pins are used to fasten axles and nuts, as well as movable parts in the automotive and agricultural sectors, among others.
This spring-type straight pin with a loop at one end is made of zinc-plated steel and offers quick, secure assembly. R-clips are widely used in the farming and building sectors in order to secure movable parts such as tractor accessories or scaffolding components.
Linch pins or lynch pins are a type of locking pin that click open and closed. Made of zinc-plated steel, they are ideal for quick joints.
This semi-circle-shaped pin, generally made of steel or stainless steel, is mainly used in joints that require regular dismantling (without specialised tools).
How pins are installed depends on the type of joint, the type of pin and your particular needs. In some cases, special tools may be required, depending on the chosen method.
The simplest method to do so is with a hammer: position the pin in the hole without excess force, then strike it lightly with a hammer until it is fully inserted in its housing. This technique is a quick and effective way of positioning the parts in relation to each other - however, be careful not to hit too hard, or you risk damaging the joint or deforming the pin.
Insert the split pin into the hole, making sure the tines are perfectly straight to prevent any clearance between the head and the part, before bending with pliers to ensure optimal hold. Should the ends of the pin stick out, feel free to cut them with the pliers.
Different install methods are used for different types of pins:
Pins may need to be extracted if they are worn or not positioned correctly. Several different methods can be used to do this:
