100mm Swivel Bolt Hole Castor – Grey Rubber Wheel, M10, 80kg

When equipment on tube legs needs a larger wheel that rolls smoothly over joints and small obstacles, runs quietly and treats floors gently, this 100mm swivel bolt hole castor is a sound choice. It has a single grey rubber wheel on a polypropylene centre, a zinc-plated pressed steel housing and one M10 bolt hole fixing that goes straight into a tube leg or threaded insert, with no top plate. Each castor is rated to 80kg and stands 122mm tall. It suits catering and prep trolleys, stainless steel tables, shop display units, mobile workbenches and light industrial equipment.

Why it works

A larger 100mm wheel

A bigger wheel rolls over floor joints, thresholds and small debris more easily than a small castor and needs less effort to push, especially when the trolley is loaded.

Grey rubber tyre – quiet and floor-friendly

The 24mm-wide grey rubber tyre on a rigid polypropylene centre absorbs small bumps and grips the floor, so the castor runs quietly and is kind to vinyl, tiles, laminate and sealed wood. Grey rubber is less likely to leave dark scuff marks than black rubber.

Bolt hole fixing for tube legs

The domed swivel head has a single central M10 hole. One bolt goes up through it into the leg or threaded insert, so the castor sits neatly under the leg with nothing sticking out sideways.

• 100mm grey rubber wheel on polypropylene centre, quiet running
• Single M10 bolt hole fixing, no top plate
• 80kg per castor, 240kg for a set of four
• 122mm total height, 83mm swivel radius
• Zinc-plated pressed steel housing

Where it's used

Catering and prep trolleys, stainless steel tables, mobile workbenches, shop display units and fixtures, laboratory and healthcare equipment, and light industrial trolleys on round or square tube legs. Best on smooth indoor floors such as vinyl, tiles, laminate, sealed wood and sealed concrete.

Choosing the right option

Check the fixing first: this castor needs an M10 bolt or M10 threaded insert in the leg; for a flat base, a top plate castor is easier to fit. Wheel size matters: a 100mm wheel rolls more easily over uneven floors than 50mm or 75mm castors, but adds height, so check the finished height of your equipment. For the load, add up the weight of the item and everything on it and divide by three rather than four, because on an uneven floor one castor is often lifted; if the answer is over 80kg, choose a heavier-duty castor. This castor has no brake: the matching 100mm braked bolt hole castor with a grey rubber wheel is the same height, so you can fit two of each for a level set that can be held in place.

Installation, use and care

Fit an M10 bolt of the right length up through the swivel head into the leg or threaded insert and tighten until the head sits flat and firm. Check the fixing after the first few weeks, keep the wheel clear of threads and debris, and wipe clean with a damp cloth. Keep the rubber tyre away from oils and solvents, which can soften rubber.

Frequently asked questions

What size bolt do I need?
An M10 bolt or M10 threaded insert. The length depends on your leg or insert. Bolts are not supplied.

What is the load capacity?
Each castor is rated to 80kg. A set of four is rated to 240kg, because the load is calculated on three castors to allow for uneven floors.

Will the wheel mark my floor?
Grey rubber tyres are less likely to leave dark marks than black rubber and run quietly on hard floors. Keep them clean to avoid transferring grit.

Is there a braked version?
Yes. The matching 100mm braked bolt hole castor with a grey rubber wheel has the same height and fixing.
