Wire diameter: 1.2 mm
Outside diameter :7.5mm
- Material: Using 45 steel (a great material for the spring, better than stainless steel and manganese steel), has excellent elasticity and fatigue resistance.
- The wire diameter: 1.2mm / Inner diameter: 5mm / Outside diameter 7.5mm/Total 9 laps
- nickel plating better corrosion resistance and surface hardness
- The compression spring is used for heated bed assembly or other equipment.
