Other fasteners

Our range includes a wide variety of fasteners – the right solution for every requirement.

Versatile connections

A solution for every application

Simple screw connections are often not adequate to ensure a sufficiently secure connection or are inappropriate for the specific context of the application. To meet your specific needs, our range includes a wide variety of other components such as threaded rods, grease nipples, shaft locks, parallel keys and turnbuckle nuts.

Types of fasteners

Threaded rods and weld stud ends
They can be set in concrete in order to attach components to them later, or they can be used as a connector between two materials. They are screwed through the elements to be fastened or connected and secured with a nut.
The key feature of weld stud ends is their suitability for welding applications. The load-bearing capacity of weld stud ends is determined in part by their own strength, but mainly by the design of the component to be welded.

Grease nipples
Grease nipples or conical grease nipples are used to lubricate bearings. They are connected to the component by the screw thread.
The pressure from the grease gun – which can be form-fitted to the nipple – pushes a ball bearing against a retaining spring. This allows the grease to pass through. When the pressure is removed, the ball bearing returns to its initial position – protecting the nipple from dirt and acting as a non-return valve to prevent the grease from escaping.

Adjusting rings
An adjusting ring is a steel ring that is attached to a shaft by means of a threaded pin. It supports the shaft against other machine parts, for example, or holds other parts in a specific position on the shaft.

Countersunk and round head solid rivets
A hole is drilled or punched in the receiving material and the rivet is guided through. The end of the rivet is then deformed to prevent it from coming out of the receiving hole. There is no need for a thread when making this connection. It is generally not possible to loosen the connection without destroying the rivet. Countersunk and round head solid rivets differ in terms of their head shape. Countersunk rivets achieve a flush finish with the receiving material, while round head rivets create an aesthetic connection.

Turnbuckle nuts
Turnbuckle nuts are used to connect two different components. Turnbuckle nuts have elements at either end such as eyes, hooks or weld stud ends, which can be used to connect the respective components. They have a left-hand thread at one end and a right-hand thread at the other. Turning the turnbuckle nut applies tensile stress to the resulting connection.

Hose clamps
Hose clamps connect hose ends either to each other or to a fixed connection. Tension is applied to the clamp via a screw. This design also allows the clamp to be loosened and closed multiple times.
The inner surface of the band is ribbed. The ribbing is rounded to protect the hose and the area around it.

Spring cotters
Spring cotters – also known as spring split pins – are used to secure components in position. Spring cotters are pushed over the component until the spring slides home. This means they can be released and reused multiple times.

Pins, split pins and grooved pins
Pins and grooved pins are used to connect components, while split pins secure connections. Pins such as taper pins or parallel pins are inserted into a pre-drilled hole in the receiving material. Grooved pins do not need a pilot hole and are inserted into the material using a hammer. Split pins are guided through a drill hole and then bent to fix them in position.

Shaft locks and parallel keys
To attach them, grooves must be made in the components to be fastened. Parallel keys are used to transmit the torque between a shaft and another component in a shaft-hub connection. A parallel key is inserted into a pre-milled keyway in a shaft to create a form-fit with a hub on the other side (with a suitable groove). It then then transfers the torque from the driving component to the driven component. Parallel keys are mainly used in mechanical engineering.
