Metal-rubber washer set GEKO 150 pcs — mixed sizes for fastening and vibration damping

Set of 150 metal-rubber washers from GEKO designed for fastening, sealing and vibration damping in mechanical and construction applications. The assortment contains multiple sizes combining a metallic core with an outer elastomer layer to improve load distribution, prevent loosening and provide sealing against dust and moisture. The mixed-size pack covers common diameters for use with bolts, screws and mounting assemblies, making it a practical supply for repairs and installations.

Advantages

Metal-rubber combination washers provide both mechanical strength and elastic sealing: the metal insert maintains shape and load-bearing capacity while the rubber outer layer absorbs vibrations and compensates for surface irregularities. The mixed-size set of 150 pieces ensures a ready supply of common sizes, reducing the need to source individual washers. These washers resist loosening under dynamic loads and offer additional protection against dust and moisture at fastening points.

Suitable for

• Automotive repairs and component mounting where vibration damping is required
• HVAC and plumbing installations that need sealed fastenings
• General construction and mechanical assemblies
• Electronics housings and control panels to isolate vibration and seal joins

Key specifications

• Pack contents: 150 washers in assorted sizes
• Construction: metal core with elastomer (rubber) outer layer
• Functionality: load distribution, vibration damping, sealing against dust and moisture
• Compatibility: suitable for use with bolts and screws of common diameters
• Typical applications: automotive, HVAC, construction, general repair

How to use

Select a washer size from the assortment that matches the bolt or screw diameter and the thickness of the materials being joined. Place the washer between the bolt head or nut and the mating surface with the rubber side facing the surface to provide sealing and vibration isolation. Tighten the fastener to the appropriate torque for the application, ensuring the rubber compresses enough to form a seal without excessive deformation. For repeated assemblies, inspect washers for wear and replace as needed.

Usage recommendations

For optimal performance, use washers with fasteners of matching diameter and avoid over-tightening, which can excessively compress the rubber layer and reduce effectiveness. Store the set in a dry, cool place away from direct sunlight and oils to preserve the elastomer. Replace damaged or hardened washers to maintain sealing and vibration isolation.
