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
Bolt Hole Castors
This compact 50mm braked swivel castor pairs a tough black polypropylene wheel with a single 10mm bolt hole for an M10 bolt and a foot-operated brake. It steers freely through 360 degrees, locks firmly when you need it to stay put, and carries up to 65kg per castor, making it a neat, secure choice for display stands, light trolleys, mobile units and tube-leg furniture.
If you are looking for a small bolt hole castor with brake, a 50mm lockable M10 castor, a black plastic braked swivel wheel or a replacement braked castor for a display unit or trolley, this castor is a simple, low-profile upgrade.
Why Choose This Castor
- ✓ Foot-operated brake locks the wheel so your equipment stays exactly where you park it.
- ✓ Single bolt hole fitting for an M10 bolt, ideal for tube legs and tube adaptors.
- ✓ Black polypropylene wheel that is light, hard-wearing and easy to wipe clean.
- ✓ 65kg per castor with a 195kg rating for a set of four.
- ✓ Zinc-plated pressed steel housing for a clean finish and good corrosion protection indoors.
- ✓ Low 72mm height keeps displays and furniture 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 65kg), which gives a safer working load on real-world floors.
Where It Works Best
This braked bolt hole castor suits shop display stands and exhibition racks, clothes rails, medical and utility trolleys, serving trolleys, mobile office units and tube-framed furniture. The brake is especially useful on displays in busy shops, trolleys that need to stay put while loaded and equipment used on smooth indoor floors.

Frequently Asked Questions
How do I fit a bolt hole castor?
Pass an M10 bolt through the 10mm 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 does the brake work?
Press the pedal down with your foot to lock the wheel and lift it to release. The castor keeps its swivel movement, while the wheel itself stops rolling.
How much weight can a set of four carry?
Each castor is rated at 65kg. For a set of four we recommend a maximum of 195kg, as only three castors are usually in full contact with the floor at once.
Should I mix braked and swivel castors?
A popular setup is two braked swivel castors and two plain swivel castors, which gives full steering with secure parking. Four braked castors give the most holding power.
Will the polypropylene wheel mark my floor?
Polypropylene is a hard wheel that rolls easily on smooth floors. On delicate or polished surfaces, a rubber wheel will be quieter and gentler.
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 with a softer tyre.
