Description
Overview:
The Mason Mate Rubber Anchor Nut M12 x 75 is a durable rubber fixing designed for secure anchoring in hollow or brittle materials where traditional expansion anchors cannot grip. Made from tough, resilient rubber in a black, flanged form, it compresses and expands inside a cavity to create a strong, vibration-resistant hold. Sized M12 x 75 (approximately 0.47 inches x 2.95 inches), it pairs with standard M12 bolts or threaded studs to clamp panels, brackets, guards, or fittings without rear access. Commonly used across construction and garden machinery, it suits equipment panels, housings, and enclosures on items such as generators and pressure washers. Sold individually for convenience. Manufacturer reference: MPN 903 2400 50PK. Part of a wider range from M4 x 11 up to M12 x 75.
Key Features:
- Robust rubber body expands uniformly to grip cavity walls and thin panels
- M12 thread compatibility; 75 mm body length (approximately 0.47 inches x 2.95 inches)
- Blind fixing: no need for access behind the panel or wall
- Helps isolate vibration and reduce rattles on machinery and equipment
- Reliable hold in a wide variety of construction materials and composites
- Simple installation into a correctly sized pre-drilled hole; tighten the M12 bolt to set
- Non-damaging to delicate or brittle substrates compared with metal anchors
- Corrosion-resistant performance as the rubber sleeve shields the fixing area
- Neat, low-profile flange for tidy finishes on visible panels
- Sold individually, making it easy to order the exact quantity required
- Part of a size range (M4 x 11 to M12 x 75) for consistent fixing across projects
Typical Applications:
Securing panels, guards, brackets, cable trays, and enclosures to cavity walls, thin sheet, plastics, composites, or preformed panels. Ideal for site equipment, garden machinery shrouds, HVAC covers, control boxes, compressors, generators, site lighting columns, and general fabrication where rear access is limited and vibration damping is beneficial.
