• Ideal for Multi-Hole Applications: Increasing the number of holes in a part reduces its weight. While creating a hole typically weakens the material, adding a dimple or ridge around the perimeter enhances strength by distributing the load evenly across the surface.
• Enhanced Strength: The raised edge around each hole reinforces the material, similar to how folding pizza into a V-shape. This slight alteration makes the slice stiffer vertically, allowing for better handling and easier bites, without changing the pizza itself.
• Effective Load Distribution: Dimpling evenly spreads stress across the surface, reducing localized weaknesses that can compromise structural integrity.
• Flush Bolt Integration: This design feature allows pan-headed bolts to be recessed into the material, keeping the bolt heads flush with the surface of the tube. It is ideal for applications that require a smooth exterior finish, preventing snagging or interference with other components. This integration is especially beneficial in scenarios where aesthetics and streamlined designs are crucial, such as in automotive and architectural applications.
