Product description
- SPRING WASHER DIN 127 Split washer at one point and bent into a helical shape. This causes the washer to exert a spring force between the fastener's head and the substrate, which maintains the washer hard against the substrate and the bolt thread hard against the nut or substrate thread, creating more friction and resistance to rotation.
- USABILITY Various metric size split lock washers have a left-hand helix, which means you can only use them with bolts that have right-hand threads to prevent clockwise rotation from vibration. When tightened, their uneven split ends bite into unhardened nuts and bolts for a tighter hold than curved or wave washers, but only for applications with clockwise rotation.
- ZINC PLATED ALLOY STEEL Hardware commonly used in mostly dry environments. The zinc plating offers temporary rust protection, but once it wears away the steel will rust. All of these washers are stronger and more wear resistant than stainless steel.
- SHIMS SUITABLE FOR General purpose engineering, automotive panel fixing, building, sheet metal, plastic fabrication, DYI.
- SPECIFICATIONS DIN 127 M12, Material- Zinc plated Steel, Hole diameter- 12.2mm, Outside diameter- 21.1mm, Thickness- 2.5mm, Pack of 25.
