Wheel bolts and wheel nuts – RDM Parts for reliable wheel mounting
Are you looking for wheel nuts, serrated wheel bolts, castle nuts, centring rings or wheel nut caps? At RDM Parts you will find a broad range of wheel fastening parts that fit the common trailer and agricultural axles, with parts from manufacturers such as ADR, PE Automotive, Bimecc, Simol and Penta.
The connection between rim, wheel and hub is safety critical: too little preload lets the wheel work and wears out the rim holes, while too much preload stretches the bolt so it loses its clamping force. Our range is therefore built around versions that match the rim and the hub exactly. You will find ball seat nuts and flange nuts in sizes M14x1.5 up to M22x1.5, wheel nuts with pressure plate and with a short or long guide, wheel nuts in 7/8 inch 11BSF, and serrated ADR wheel bolts, also in GEOMET finish. In addition we supply castle nuts with the matching spring pins from M18x1.5 to M70x2.0, centring rings and centring sleeves – including 20.2/32 mm, 22.2/32 mm and B3/B2 IHC – wheel nut caps and a loosening indicator for a 32 mm spanner that makes a loosening wheel nut immediately visible. When selecting, pay attention to the seat: ball, flat or with a separate pressure washer must match the rim, because the wrong combination gives no flat contact and therefore no reliable clamping force.
To find the right part quickly and with certainty, many of our customers consult the parts book or parts manual of the axle or machine. With the part number you can search the RDM Parts search bar for the matching part directly.
If you cannot find a part, ask the parts specialists at RDM Parts. With years of experience they will help you select the right size, thread and seat quickly and expertly, so you do not fit on guesswork.
