Durable Material: White insulation spacer assortment kit is made of high-quality nylon, which is rust-resistant, insulated, high in strength, good in toughness, and has long-lasting durability and stability Excellent Insulation Properties: Nylon insulating washers are non-conductive, effectively isolating electrical currents to reduce the risk of short circuits and leakage. They maintain stable insulation performance even under tightened screws or during prolonged fixed applications, helping to safeguard the normal operation of circuits and equipment Versatile Design: Cylindrical spacers and washers with clearance holes can be used as sleeves, spacers, or washers, used as insulating materials in electronic devices, or to prevent electrolysis between different metals Lightweight Design: Compared to metal isolation columns or metal casings, it offers reduced weight while maintaining essential strength and support performance, thereby avoiding additional structural burden Wide Application: Widely used in electrical products such as PC boards, 3D printers, TV wall sockets, nail boards, etc.; suitable for commercial or household appliances, automobiles, ships, and other threaded/bolted power equipment
