Description
Overview:
The Mason Mate Rubber Anchor Nut, M6 x 25, is a versatile expanding fastener for secure, single-sided fixing in thin sheet, hollow sections, and other cavity materials. It uses a durable black rubber body that expands as the M6 screw is tightened, gripping the internal profile of the hole to create a stable anchor. This design helps isolate vibration and can provide a light seal against dust and moisture. It is suitable for a wide range of construction and garden machinery tasks, such as fixing guards, covers, control boxes, brackets, and accessories where rear access is limited. Size M6 x 25 refers to an M6 thread with a 25 mm body length. Sold individually under the Mason Mate brand for dependable day-to-day use.
Key Features:
- M6 thread with 25 mm rubber body length for common fastening needs
- Expands inside the hole to grip cavities securely when the screw is tightened
- Ideal for thin sheet, plastics, composites, and hollow sections without rear access
- Rubber body helps damp vibration and reduces noise transmission
- Can help seal the fixing point against dust and light moisture ingress
- Distributes load to reduce risk of cracking delicate materials
- Simple to fit with a standard M6 machine screw or bolt
- Removable and replaceable by undoing the screw for easy maintenance
- Suitable for use across many construction materials and site conditions
- Sold individually; also available in a wider range (M4 x 11 to M12 x 75) for other needs
Typical Applications:
Commonly used to mount panels, guards, fairings, light brackets, number plates, sensors, and small enclosures on construction and garden machinery. Useful for securing components to thin steel, aluminium, plastic, GRP, or laminated panels where conventional nuts and washers are impractical. Ideal for repairs, retrofits, and adding accessories without access to the rear side.
