Product description Key benefits Protects mating surfaces from nut abrasion, preventing damage during installation and removal. Distributes clamping pressure evenly across the connected part to reduce localized stress and extend service life. Made for durability and wear resistance to withstand repeated use in mechanical assemblies. What this washer does Acts as a protective interface between the nut and the connected component to minimize surface wear. Spreads the load from the nut over a larger area, helping to preserve the integrity of the joint and connected parts. Designed for long-lasting performance in demanding applications. Material and performance Material: 304 (stainless steel) Constructed for toughness and wear resistance to handle mechanical stress and frequent tightening. Compatibility and sizes Available sizes: M10, M12, M14, M16, M18, M20, M22, M24, M27, M30 Suitable for use with common fasteners and assemblies across a range of equipment types. Typical applications Plumbing and fixtures: Use with taps and valves to protect mounting surfaces during installation and service. Pneumatics and motion systems: Fit under nuts on air cylinders and actuator mounts to reduce wear on brackets and end caps. Industrial equipment and vehicles: Ideal for pumps, bearings, automotive assemblies, and other machinery where bolted connections see repeated maintenance. Practical use scenarios Replacing a faucet: Place the washer under the mounting nut to prevent the nut from scoring or deforming the sink or fixture flange while maintaining an even clamp load. Mounting an air cylinder: Install washers under the cylinder mounting nuts to distribute clamping force and protect the mounting plate from abrasion during operation and maintenance. Securing a bearing housing: Use the washer under the bearing-housing nuts to reduce localized stress and preserve the mating surface when torque is applied. Purchase information Available in the listed metric sizes (M10–M30) to match a wide range of fasteners and assembly needs. Material specification: 304 for consistent mechanical performance and wear resistance. Specifications (summary) Function: Surface protection and pressure distribution under nuts Material: 304 (stainless steel) Sizes: M10, M12, M14, M16, M18, M20, M22, M24, M27, M30 This washer is a straightforward, durable solution for protecting connected parts from nut abrasion and for improving the longevity of bolted joints.
