WASHERS BACKUP STAINLESS SS4 (500pk) - 3M - Marson

The 3M - Marson MR40654 Stainless Steel Square Backup Washers (500pk) are essential components designed to reinforce riveted joints in professional automotive and industrial applications. These backup washers significantly increase the bearing surface area, distributing the rivet's load over a broader region to prevent pull-through and enhance the overall strength and longevity of the fastening. Supplied in a convenient pack of 500, they are ideal for high-volume use by professional technicians and mechanics.

Key Features

• Stainless Steel Construction: Crafted from durable stainless steel, these washers offer exceptional resistance to corrosion, rust, and harsh environmental conditions, ensuring long-lasting performance in demanding settings.
• Square Design: The square form factor provides an effective load-spreading surface, particularly beneficial for securing 1/8 inch hex rivets.
• Optimal Load Distribution: With a designated size of 1/2 inch, these backup washers effectively distribute the force of the rivet, minimizing stress on materials and protecting against damage, especially when working with softer substrates.
• Compatibility: Specifically engineered for use with 1/8 inch hex rivets, ensuring a precise fit and reliable performance.
• Professional Pack Size: Each package contains 500 washers, providing ample supply for extensive repair and fabrication projects.
• Enhanced Durability: Stainless steel's inherent strength and resistance to extreme temperatures contribute to the durability and reliability of riveted assemblies.

Applications

These 3M - Marson backup washers are indispensable for a variety of professional applications where robust and reliable rivet fastening is critical. They are particularly effective when working with thin materials, soft substrates such such as plastics, fiberglass, or soft aluminum, and in situations where existing holes may be slightly oversized or irregular. Common use cases include automotive body repair, panel attachment, general industrial fabrication, and any scenario requiring additional support to prevent rivet pull-through or to reinforce a riveted joint against vibration and stress. Matching stainless steel washers with stainless steel rivets is recommended to prevent galvanic corrosion in wet or marine environments.
