This is a comprehensive selection of round spacers designed to facilitate electronics and mechanics projects. They are categorized into three primary types based on their wall thickness: 1mm, 2mm, and 3mm. The available sizes range from 1 to 30mm, incrementing in 1mm steps. Sizes above 30mm are offered at 5mm increments. Type A round spacers feature thin walls, making them ideal for applications requiring minimal mechanical performance, such as electronics board assembly. Type B round spacers represent the most common size of Round spacers available. Type C round spacers boast large walls, providing exceptional mechanical performance, perfect for demanding projects like 3D printer assemblies.
