Replacing an old castor? Measure between the centres of two fixing holes along the long edge, then across the short edge, and compare with the hole centres above. Allow the swivel radius as clear space around each castor so it can turn freely.
Load check
How we work it out: on a real floor one castor is often carrying little or nothing, so we share the weight across one fewer castor than you fit (with 3 castors, across all 3). Tick the box to add a 30% margin for rough use.

Details & FAQs
Light Duty Bolt Hole Castors
This compact 50mm swivel castor combines a quiet grey rubber tyre with a polypropylene centre and a single M8 bolt hole fitting. It turns freely through 360 degrees, rolls smoothly and gently on indoor floors, and carries up to 50kg per castor, making it a neat choice for shop fittings, display stands, small trolleys and tube-leg furniture.
If you are searching for a small bolt hole castor, a 50mm grey rubber swivel wheel, an M8 castor for furniture or a quiet non-marking style castor for a display unit, this castor offers a tidy, low-profile upgrade.
Why Choose This Castor
- ✓ Grey rubber tyre for quiet, smooth rolling that is kind to indoor floors.
- ✓ Single bolt hole fitting for an M8 bolt, ideal for tube legs and tube adaptors.
- ✓ Full 360 degree swivel for easy steering in tight spaces.
- ✓ 50kg per castor with a 150kg rating for a set of four.
- ✓ Zinc-plated pressed steel housing for a clean finish and good corrosion protection indoors.
- ✓ Low 70mm height keeps furniture and displays close to the floor.
* The set-of-four figure allows for only three castors being in full contact with the floor at any time (3 x 50kg), which gives a safer working load on real-world floors.
Where It Works Best
This small grey rubber bolt hole castor suits shop display stands and clothes rails, light hotel and serving trolleys, medical and utility trolleys, mobile office units, small workbenches and tube-framed furniture. The rubber tyre makes it a good match for offices, shops, hotels and other indoor spaces where quiet movement and floor care matter.

Frequently Asked Questions
How do I fit a bolt hole castor?
Pass an M8 bolt through the 8mm hole in the top of the castor and secure it into your furniture, a threaded insert or a tube adaptor fitted inside the leg.
How much weight can a set of four carry?
Each castor is rated at 50kg. For a set of four we recommend a maximum of 150kg, as only three castors are usually in full contact with the floor at once.
Is the grey rubber wheel quiet and floor friendly?
Yes. The grey rubber tyre rolls quietly and is gentle on wood, vinyl, tiled and other smooth indoor floors.
Does this castor have a brake?
No, this is a plain swivel castor. For equipment that needs to stay in place, pair it with braked castors of the same size.
What is the total height of the castor?
The total castor height is 70mm from the floor to the top of the fitting, which keeps equipment low and stable.
Is this castor suitable for outdoor use?
It is best suited to indoor use on smooth, level floors. For rough ground or outdoor areas, choose a larger wheel.
