RS PRO Stainless Steel Lock Washer M6 DIN 7980, A2 Grade, Plain Finish 530-848

The RS PRO 530-848 Stainless Steel Lock Washer is engineered to deliver superior fastening reliability in critical industrial and machinery environments. This washer incorporates an M6 size and conforms to the DIN 7980 specification, ensuring it meets strict dimensional and performance standards required for professional applications.

Constructed from A2 grade stainless steel (type 304), this lock washer provides excellent corrosion resistance and mechanical strength, making it ideal for use where exposure to moisture or harsh conditions is expected. The plain finish delivers a clean, unobtrusive look suitable for a wide range of installations.

Featuring an external diameter of 16 mm and an internal diameter of 8.4 mm, the washer is precisely sized for compatibility with standard M6 bolts and screws. Its 2 mm thickness ensures robust securing and enhances its ability to absorb vibrations, significantly reducing the risk of fasteners loosening over time. The square single coil design adds mechanical effectiveness, especially in assemblies subject to dynamic motion or vibration.

Lock washers like this RS PRO model are intended to be placed between a bolt, nut, or another washer and the mounting surface, acting as a tension buffer against external forces. This helps to maintain clamping force and prevent fasteners from backing off, particularly in machinery, construction equipment, HVAC systems, and household appliances such as washing machines.

Every RS PRO washer is manufactured to DIN 7980 standards, granting designers and engineers confidence in dimensionally accurate and reliable products. The A2 material grade assures compatibility with industry best practices and long-term durability.

Typical industrial use cases include manufacturing machinery, assembly lines, automotive clamping, agricultural equipment, and laboratory installations, where both vibration mitigation and corrosion resistance are essential.
