Description
Overview:
The 31mm Wheel Nut Indicator (MPN 310 031) is a small, high‐visibility device that clips over a wheel nut to show any movement at a glance. Made from durable, weather‐resistant polymer in bright yellow, it is designed for heavy‐duty use on commercial vehicles, trailers, buses, coaches, construction plant and agricultural equipment. It fits 31 mm across‐flats (AF) hex nuts, which is approximately 1.22 inches AF, and is sold individually so you can match the exact quantity required per wheel. By aligning the pointers to a consistent pattern, any shift in position warns of a loosening nut, helping to prevent wheel detachment and supporting safe, documented walk‐round checks. It installs by hand without tools and is easy to monitor during daily inspections and routine maintenance.
Key Features:
- Fits 31 mm AF hex wheel nuts (approximately 1.22 in AF) for a secure fit.
- High‐visibility yellow pointer for quick visual checks during inspections.
- Tough polymer construction resists UV, moisture, road grime and typical brake heat.
- Provides a clear indication of nut movement to help prevent wheel loss.
- Push‐on design; no tools, drilling or torque change required.
- Reusable and simple to realign after re‐torque or wheel service.
- Suitable for steel or alloy wheels with exposed wheel nuts.
- Sold individually to suit any wheel configuration or fleet quantity.
- Aids compliance with fleet safety procedures and maintenance schedules.
Typical Applications:
Used on HGVs, LGVs, buses and coaches, refuse trucks, tippers, trailers (box, flatbed and plant), agricultural trailers and implements, and site machinery where wheel security is critical. Ideal for daily walk‐round checks, post‐service monitoring, and operations with frequent stop‐start or rough‐terrain use that can increase the risk of wheel nut loosening.
Also known as:
Torque indicator, wheel nut tell‐tale, loose wheel nut marker, wheel safety pointer cap, wheel loss indicator, wheel nut movement tag, wheel nut visual marker, wheel security indicator, wheel nut alignment marker.
