Description
Overview:
The Mason Mate Rubber Anchor Nut, M8 x 25, is a black rubber expansion fixing designed to secure components where rear access is limited or unavailable. It features a durable rubber body with a threaded metal insert that grips firmly when an M8 bolt is tightened, expanding behind the panel or within a cavity. This creates a strong, vibration-damping hold without damaging thin materials. Suitable for construction and garden machinery, it is commonly used on guards, panels, covers, fairings, and housings across equipment such as generators, pressure washers, mowers, compactors, and mixers. The 25 mm length helps accommodate a range of panel thicknesses and cavity depths. Sold individually, it lets you buy the exact quantity needed for maintenance, repairs, and small assembly tasks.
Key Features:
- M8 thread with 25 mm length for versatile use across machinery and equipment
- Rubber body expands to lock securely in blind holes and cavities
- Threaded metal insert provides reliable engagement for bolts and screws
- Helps reduce vibration and loosening on panels and thin-walled sections
- Suitable for metal, plastic, and composite panels without needing rear access
- Helps seal and cushion the fixing point, assisting with dust and splash resistance
- Clean, easy installation with a standard M8 bolt; removable and replaceable
- Durable construction for consistent performance in workshop and site conditions
- Sold individually to match exact project quantities
- Wider range available from M4 x 11 to M12 x 75 for other requirements
Typical Applications:
Ideal for mounting guards, control panels, plastic covers, fairings, brackets, small accessories, and light fixtures on construction and garden machinery. Useful for thin sheet metal, fibreglass, and plastics where clamp loads must be spread and access is one-sided. Common in servicing generators, compressors, mixers, lawnmowers, strimmers, and pressure washers.
Also known as:
Often referred to as a well nut, rubber well nut, blind rubber anchor, rubber rivet nut, rubber captive nut, or cavity anchor. These terms describe the same expanding rubber fixing used for secure, vibration-damped fastening in thin or hollow sections.
