Metal Washers, Collars（I.D. Shape：Straight Page2）

Metal washers and collars are versatile fasteners designed to distribute loads, provide spacing, and ensure precise positioning in various mechanical and engineering applications. These components are essential in preventing loosening and damage to surfaces during the tightening of bolts and screws. Available in multiple materials such as stainless steel, steel, brass, and aluminum, they offer varying degrees of strength, corrosion resistance, and weight. Customizable in terms of inner and outer diameters, thickness, and surface treatments like black oxide and nickel plating, metal washers and collars cater to specific needs, ensuring optimal performance and longevity in demanding environments.
