Stainless Steel Flat Screw Torsion Springs for Door Handles Inner diameter: 20 mm | Wire size: 1.2mm x 2.4mm What this spring does Provides reliable torsional return for door handles, ensuring smooth, consistent closing and resetting action. Designed as a direct-fit component for handles that accept a flat screw torsion spring with a 20 mm inner diameter and 1.2mm x 2.4mm wire size. Key benefits — why you need it Smooth operation: polished, smooth surface reduces friction and wear on mating parts for quieter, more consistent performance. Long service life: engineered for fatigue resistance and good resilience so the spring maintains its shape and return force through repeated cycles. Easy to fit: precise inner diameter and wire dimensions help ensure correct seating and reliable function when replacing or assembling door handles. Durable construction: stainless steel material provides mechanical strength appropriate for door-hardware applications. Important attributes Function: torsion/return spring for door handle mechanisms. Compatibility: for door handles designed to accept a flat screw torsion spring with 20 mm inner diameter and 1.2mm x 2.4mm wire size. Confirm these dimensions match your handle before ordering. Material: stainless steel. Performance: smooth surface finish, high plasticity, fatigue resistance, and good resilience as specified. Practical use scenarios Replacement part: swap into a worn or broken handle spring to restore smooth return action on interior or exterior doors. Repair and refurbishment: used by maintenance and repair technicians to rebuild door-handle assemblies without replacing the entire mechanism. Custom fabrication: suitable for small-scale production or custom handle projects that require a flat torsion spring with these exact dimensions. Installation note Verify the handle’s required inner diameter and wire size prior to installation. The spring is intended as a component for handles designed around these dimensions and functions.
