Professional Applications & Engineering Value
This Nylon 6/6 Plastic Sleeve Washer is engineered to solve common industrial challenges where metal components fail. Its off-white Nylon 6/6 material provides excellent resistance to fuels, oils, and many chemicals, preventing degradation in demanding environments like automotive, electrical enclosures, and outdoor machinery. The sleeve type design offers superior bearing surface and helps absorb shock and vibration, which is critical for maintaining assembly integrity in high-stress applications. With a Rockwell R108 hardness, it withstands wear while the wide temperature range from -40°F to 180°F ensures performance stability, making it an ideal choice for industrial washers requiring durability without the weight or corrosion of metal.
Specification Summary & Compliance
This washer features an ID of 0.255", OD of 0.467", and an overall height of 0.171", designed for use with 1/4" screws in inch system measurements. It is manufactured from Nylon 6/6 plastic with a hardness of Rockwell R108 and is compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial components.
