630 Piece Metric Hex Nut & Washer Assortment - M4 to M12 - Steel - Zinc

Spring Washers Are Formed In An Irregular Shape To Provide Lighter Resistance And Distribute Pressure In Low Strength Fastening. Spring Washers compress to act like a spring and deflect when loaded, providing a preload between the two joined surfaces. Fasteners are used where assemblies need a part to eliminate rattle, maintain assembly tension, compensate for expansion or contraction, or to absorb intermittent shock loads for long lasting durability.

DIN 6331 hexagon nuts are used for applications where frequent tightening and untightening is required, the flange of the nut eliminates the need for washers.
