Packaging: Each pack contains 100 Round Spacer Washers M4-7x5(Ø7×D5 mm). KINETOX offers a variety of sizes to precisely fit different application scenarios. M4: 7×3/5/8/10/12 M6: 11×3/5/8/10/12/15/18/20/25 M8: 14×3/5/8/10/12/15/18/20/25 The plastic spacers fit M4/M6/M8 screws and protect printed circuit boards. Round ABS Spacers: These nylon washers offer excellent insulating properties and are suitable for extreme temperatures from -40°C to 120°C. The ABS plastic washer increases the contact surface, prevents screw deformation and corrosion, and reduces the risk of short circuits. Resistant to oil and chemicals, they extend their service life. Spacer washers provide long-term stability outdoors. Precise sealing design: Round spacer washers offer high sealing force, preventing screw loosening/leakage and boosting structural stability. The plastic spacer design dampens mechanical stress, protecting printed circuit boards/printers from corrosion/wear. Round spacer washers block electrochemical corrosion of metal parts, significantly extending equipment lifespan. Easy installation: The plastic washers have a smooth, burr-free surface, effectively preventing damage to electrical components during installation and removal. Their threadless design allows for direct screw insertion, making installation and removal quick and easy. Ideal for maintenance and repairs, the seal adjustment is easy to ensure your equipment functions properly. Versatile insulating sleeves: Plastic spacers are used in various industries. Electronics: PCB screw insulation, short-circuit protection for enclosures, sealing of cabinets. Automotive: Motor wiring, sensor sealing. Mechanical: Rustproofing of bearings, sealing of gearboxes, hydraulic damping. Exterior: Solar mounts, sealing of LED lamps. Round spacers: optimal protection for stability and equipment lifespan.
