Professional Applications & Engineering Value

These 100° countersunk washers are precision-engineered to solve common industrial challenges, such as fastener loosening and surface indentation. Made from 18-8 Stainless Steel, they offer exceptional corrosion resistance, making them ideal for outdoor, chemical, or high-moisture environments like marine equipment and food processing machinery. The 100° countersink angle ensures a smooth, flush mount with No. 10 screws, eliminating protrusions that could cause injury or interfere with moving parts. This design, combined with the Rockwell B83 hardness, provides reliable performance in heavy-duty applications, reducing maintenance needs and extending equipment lifespan. By distributing load evenly across surfaces, these washers prevent damage to softer materials, offering a cost-effective solution for industrial washers in construction, automotive, and aerospace sectors.
