Starlock® push-on fasteners Push on - done!

Starlock® lock push-on fasteners have been developed for applications requiring fast, durable and efficient fastening on smooth (non-grooved) axles, shafts or cylindrical journals made of metal or plastic.

Starlock® eliminates the need for costly tapping and grooving of the shaft and facilitates quick assembly.

Once in position, our Starlock® lock washers are so secure that they cannot be removed from the shaft without destroying it.

Manufactured from spring and stainless steel, Starlock® is available in a variety of designs and finishes both with and without decorative caps.

Push-on fasteners with decorative cap

The decorative caps conceal the end of the shaft, giving your application an attractive appearance.

The standard and trapezoidal caps are made of stainless steel, the depth cap is galvanised steel.

We also offer standard and trapezoidal caps made of aluminium with a black cap. Our Starlock with plastic cap made of PA6 material can be supplied in any RAL colour.

Starlock® with standard cap for imperial and metric shanks

The standard cap is made of stainless steel 1.4016 and has a dome-shaped appearance. The height is selected so that the Starlock can be pushed on sufficiently to provide a secure hold.

Starlock® with trapezoidal cap for imperial and metric shank

The trapezoidal cap is made of stainless steel 1.4016. The Starlock can be pushed on further than with the standard cap, which can be an advantage in some applications.

Starlock® with depth cap for imperial and metric shanks

The depth cap is galvanised steel. This cap provides the maximum push-on depth.
