Hexagonal head autoblock 1.5mm aluminium retaining bush

Precision in every detail: the Scaleauto SC-8175F red aluminium fixing bushing

When preparing a slot car, small components make the difference between a fair assembly and a truly precise one. The SC-8175F fixing bushing from Scaleauto meets that need exactly: made from red anodised aluminium, with a height of 1.5 mm, hexagonal head, and autoblock system, it is designed to provide a firm and controlled fit wherever it is installed.

Main features

• Material: red anodised aluminium.
• Height: 1.5 mm.
• Hexagonal head: facilitates tightening and loosening with an allen key or similar, without the risk of slipping.
• Autoblock system: prevents unwanted loosening during competition or running, maintaining the fit at all times.

Function and performance

The autoblock system is particularly valuable in applications where motor vibrations or track impacts could compromise the fastening of components. Thanks to this mechanism, the bushing remains locked in the chosen tightening position, eliminating the need for frequent retorques. The hexagonal head allows for precision tool use, which is especially useful in tight spaces within the chassis.

The red anodised aluminium not only adds a distinctive visual touch—common in the aesthetics of competition setups—but also offers a good balance between lightness and mechanical strength, without adding unnecessary weight to the assembly.

Assembly and preparation

For proper assembly, we recommend using the appropriate allen key for the size of the hexagonal head and applying the correct tightening: the autoblock system already takes care of preventing loosening, so there is no need to exceed the torque. Excessive force could damage the thread or the component being fastened. If working with delicate resin or plastic chassis, caution should be exercised.

Frequently asked questions

What is an autoblock fixing bushing used for?

An autoblock fixing bushing is used to securely fasten components, preventing the tightening from loosening due to vibrations or impacts during running or competition. The autoblock system ensures that the adjustment position remains stable without the need for frequent retorques.

What advantage does the hexagonal head offer over other types?

The hexagonal head allows for the use of precision allen keys, facilitating controlled tightening even in very tight spaces within the chassis. It reduces the risk of tool slipping and, therefore, damaging the component or adjacent parts.

Does anodised aluminium offer advantages over steel in this type of part?

In slot applications where weight is a relevant factor, anodised aluminium provides a weight reduction compared to steel without compromising the necessary strength for this type of fastening component. Anodising also protects the surface against corrosion and wear.

Can I use this bushing on chassis from different manufacturers?

Compatibility depends on the thread diameter and the available space in the chassis. We recommend checking your chassis specifications or consulting with our team before assembly to ensure the measurement is correct.
