The Checklink® is a dual purpose loose wheel nut Indicator combined with a nut retaining function. 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 Checklink® retaining function also reduces the severity of wheel nut loosening, thus reducing the likelihood of wheel nuts from completely backing away the wheel hub.
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.
