RS PRO Steel Bright Zinc Lock Washers M5 DIN 7980, Spring Type, 8.8mm OD, 5.1mm ID, 1.6mm Thick, Steel, Pack of 250 526-833

RS PRO 526-833 Steel Bright Zinc Lock Washers, M5, DIN 7980, are engineered for secure fastening of nuts and bolts in demanding industrial, mechanical, and fluid power environments. These spring-type split washers are manufactured from high-grade A2 steel and feature a bright zinc plating, offering both strength and outstanding resistance to corrosion. The lock washer is specifically designed for M5 screw and bolt applications, providing a reliable anti-loosening mechanism that is essential in assemblies subject to strong vibration or harsh chemical exposure.

The 526-833 model measures 8.8 mm in external diameter and 5.1 mm in internal diameter, with a thickness of 1.6 mm, conforming to DIN 7980 standards. The spring coil and split design enable the washer to absorb the initial turning force applied during tightening, ensuring the fastener remains secure over time. Its construction binds tightly against the nut or bolt upon fastening, visibly closing under the weight to signal correct installation.

Steel construction ensures longevity and durability even in heavy-duty scenarios, while the zinc-plated finish protects against rust and degradation in challenging environments. These washers are supplied as a bulk pack of 250 units, making them ideally suited for maintenance, manufacturing, construction, and industrial projects where consistent quality and large quantities are required.

These lock washers are recommended for equipment subject to persistent vibration - such as HVAC machinery, automotive assemblies, water treatment plants, manufacturing facilities, and laboratory setups. Their use helps maintain structural integrity by preventing the loosening of critical fasteners, minimizing maintenance needs and downtime.
