The Marson 40660 aluminum backup washers are designed for use with 3/16" blind rivets to provide additional bearing surface and strength in fastening applications. These AS10 series washers help distribute load across a wider area, preventing pull-through in soft materials or oversized holes.

Key Features:

• Material: Aluminum construction for lightweight, corrosion-resistant performance
• Size: 3/16" round washers compatible with standard 3/16" blind rivets
• Quantity: 500 washers per package for high-volume projects
• Application: Ideal for automotive, marine, HVAC, and general fabrication work
