The Checklink® has dual functionality. This product from Checkpoint-Safety can be used as a loose wheel nut indicator as well as a wheel nut retainer. The Checklink® attaches to adjacent wheel nuts and should wheel nuts start to loosen, will indicate so through the visual and clear bending and deformation of the link between the nuts.

The retaining function of the Checklink® aims to reduce the severity of wheel nut loosening and as a result this will reduce the likelihood of wheel nuts from completely backing away the wheel hub.

The Checklink® is available in a range of sizes, aiming to cover a wide scope od applications throughout agricultural, industrial, mining, military and commercial vehicle sectors, amongst many others.

The primary functions of Checklinks® are to:

·      Provide a clear visual indication of nut movement, particularly useful and applicable for commercial vehicle wheels

·      Provide a wheel nut retaining function to reduce wheel nut loosening and reduce the likelihood of wheel nuts from completely backing off the wheel hub

·      Provide an indication of wheel overheating which is otherwise difficult to detect, usually as a result of brakes sticking or problems with the bearings, through the use of specific product material melting points (Standard and High Temperature options available)

·      Provide a clear visual commitment to roadworthiness and professionalism to other road users, customers, health and safety, road and transportation associations such as DFT, HMRC Customs and Excise, VOSA, HSE, FTA and RHA.

The primary benefits of fitting Checklinks® are:

✓ Improved safety of fittings where nuts are a critical structural component, such as on vehicle wheels and industrial/commercial structures

✓ Facilitates the ease of walk around and visual checks or audits to locate problems with fixtures or fittings where nuts are used as a critical component

✓ Improved security of the nuts through the utilisation of a retainer function

✓ Reduction in vehicle downtime

✓ Reduction in maintenance costs resulting from accurate locating of nut loosening or wheel overheating

✓ Improved professionalism, roadworthiness and safety related company image or reputation

✓ Cost effective and quick solution to implement

Additional information

For Checklink® best fitting practice, please see the downloadable fitting instructions PDF below. Designed to be fitted on vehicles without trims/step rings on the wheels. This is due to the design of the Checklink not allowing it to fit through the access hole on the trim/step ring.

The Checklinks® should be fitted after the nuts on the vehicles’ wheels have been tightened to the manufacturers recommendations. Once they are fitted, they should be monitored closely to check for any deformations. If there are any deformations, appropriate action can be taken.

The Checklinks® are available in Standard and High Temperature (HT). Both are manufactured with the highest quality virgin polymers and therefore resistant to water/moisture, oil, road salt, detergents and most other common contaminants/solvents.

Checklinks® are sized by the corresponding measurement (in millimetres) across the flats of the hexagonal nut fitting. Current sizes available* include (in mm):

19, 21, 22, 24, 27, 28, 30, 32, 33, 38

*Available stock levels vary for each size and colour in accordance with demand for each size. For further information or questions please contact us.

The standard colours for Checklink® are Fluoro Yellow and Red. Other colours are available subject to minimum order, please enquire by contacting us.

Made from the same material as Checkpoint®, the Checklinks® are available in Standard with a melting point of 125˚C. Also available in High Temperature (HT) with a melting point of 165˚C, subject to minimum quantity orders.
