Koelner/Rawlplug UNO 10 x 36 mm universal wall plug with screw is a fastening solution designed for light to medium duty attachments in a variety of base materials. Supplied as a pack of 50, the UNO system integrates plug expansion and screw fixation to make installation of fixtures, shelves and fittings quicker and more reliable in domestic and light-construction environments.
Advantages
The UNO plastic wall plug features a combined expansion and screw-grip design that provides stable anchorage in concrete, solid brick, hollow brick and plasterboard where specified. Its geometry reduces splitting risk in masonry and improves pull-out resistance compared with simple straight plugs. Supplied with compatible screws, the pack of 50 ensures consistent performance across multiple fixings and reduces the need to match separate screws and plugs on site.
Suitable for
- Fixing light shelves and cabinets to concrete and brick walls
- Mounting small radiators, towel rails and bathroom fittings into masonry or plasterboard
- Installing conduit clips, cable trays and lightweight brackets
- General household repairs and DIY projects where medium holding strength is required
When it may not be suitable
This universal plug is intended for light to medium loads; it is not designed for heavy structural loads, high-shear applications or critical safety fixings such as load-bearing metal supports or large wall-mounted TVs without additional mechanical anchors or chemical resin anchors. For hollow or thin-walled substrates under high load, specialized anchors designed for those substrates should be used.
Key specifications
- Plug length: 36 mm
- Plug diameter: 10 mm
- Pack quantity: 50 pieces (plugs supplied with matching screws)
- Material: durable plastic plug with metal screw
- Suitable substrates: concrete, solid brick, hollow brick, plasterboard
- Intended load category: light to medium loads (non-structural)
How to use
Drill a hole in the chosen substrate using a 10 mm masonry drill bit to the depth of the plug length. Clean out dust from the hole, insert the UNO plug flush with the surface, position the fixture, and drive the supplied screw until the plug expands and secures the fixing. Avoid over-tightening the screw to prevent deformation of the plug or damage to the base material. For hollow or brittle substrates, check manufacturer guidance for recommended maximum loads and consider using a dedicated hollow-wall anchor if required.
What to consider before purchase
- Verify wall material and thickness to ensure compatibility with a 10 x 36 mm plug
- Check required load capacity for your application and whether additional anchors are needed
- Confirm that the supplied screw length and diameter match the fixture thickness
- For heavy or safety-critical installations, consider mechanical or chemical anchors instead
Usage recommendations
Use a clean, correctly sized masonry drill bit and blow out dust before insertion for optimal holding. For repeatable results in multiple fixings, mark drill depth with tape and test one anchor before completing the entire installation.
