Metric screw insulators

Primarily intended as isolation between a screw and component of a different material, steel and glass for instance, or to stop damage to liftweight materials when fixed with screws, thes insulators could also be used as bearings in lightly loaded applications.

本数据集旨在作为螺丝与不同材质组件（如钢与玻璃）之间的隔离介质，或用于防止在螺丝固定时对承重材料的损害。此外，这些绝缘体在轻载应用中亦可用作轴承。
