Description
Overview:
The Rubber Anchor Nut M4 x 25 is a versatile, vibration-damping fastener for secure fixing into panels, thin-walled sections, and pre-drilled cavities. Made from durable black rubber, it compresses and expands as an M4 screw or bolt is tightened, gripping the hole to create a firm, blind-side fix without damaging the surrounding material. This makes it ideal for construction and garden machinery, including mowers, generators, compactors, and site equipment, as well as enclosures and fabrications. The 25 mm body length offers good grip depth for a reliable hold, and the M4 thread suits standard metric machine screws. Sold individually for convenience, and identified by MPN 903 2391, it is a practical choice for repairs, upgrades, and routine maintenance where access is limited to one side.
Key Features:
- Size: M4 thread, 25 mm body length for dependable engagement
- Expands as the screw is tightened for a strong, blind fixing
- Durable rubber construction helps absorb vibration and reduces loosening
- Minimises damage to thin panels and brittle materials compared to metal anchors
- Works with commonly drilled holes in wood, metal, plastics, and masonry
- One-sided installation - ideal where the rear of the panel is inaccessible
- Provides a degree of sealing and cushioning around the fixing point
- Suitable for securing light brackets, covers, guards, and accessories
- Sold individually to match exact job quantities and reduce waste
- MPN: 903 2391 for easy identification and reordering
- Available range includes sizes from M4 x 11 up to M12 x 75 to suit varied hole depths
Typical Applications:
Mounting guards, covers, and panels on lawn mowers, generators, compactors, and small plant; fixing brackets, cable clips, and accessories to thin sheet metal; securing components to plastic or fibreglass housings; attaching nameplates and light fittings; assembling enclosures and HVAC panels; general maintenance where a tidy, removable blind fixing is preferred.
