Product Description
šŸ”© Product Overview Keep your DIY bench, repair kit, or workshop stocked with these precision spring steel compression (pressure/coil) springs. Supplied in a pack of 10 pieces, they feature a fine wire diameter of 0.8 mm or 0.9 mm and come in various free lengths/outer diameters to suit small-mechanism work. They deliver reliable push-back/return force and are ideal when replacing lost or fatigued springs in compact assemblies .
āœ… Key Features
  • Material: Spring steel — good elasticity, fatigue resistance, and toughness for repeated compression cycles (darker/oxide tone typical of spring steel; not stainless — see note below) .
  • Wire Diameter: 0.8 mm / 0.9 mm (select the option that matches your load/stiffness needs; 0.9 mm gives a slightly firmer rate).
  • Type: Helical compression / pressure coil spring; closed/flat-end style on most sizes for stable seating.
  • Quantity: 10 pieces per order (assorted or single size/length per option selected).
  • Action: Axial compression stores energy and pushes back when released (Hooke’s-law / return-spring action) .
āš™ļø Common Applications
  • Appliance & electronics repair: switches, buttons, battery contacts, latches, pen/click mechanisms .
  • DIY mechanisms, 3D-printed parts, RC models, robotics, and small machines .
  • Furniture hardware, locks, toys, tools, and general shop repairs .
  • Shock absorption, vibration damping, and return/reset functions in compact spaces .
šŸ“ How to Choose / Install
Match the wire diameter (0.8 or 0.9 mm), outer diameter, and free length to your original spring or mechanism clearance. Compression springs store energy when pressed axially and push back when released . Do not compress beyond the solid/coil-bound height repeatedly, and avoid overloading — verify deflection/load for your use. For installation in tight spaces, use fine tweezers/needle tool and compress slowly to avoid flicking .
