SUS316 Double Arm V Shape Torsion Spring with Hook Ends for Pruning Shears &

Our stainless steel torsion spring with hook ends, also known as double arm torsion spring and v shape torsion spring, is heavy-duty torsion hardware specially engineered for handheld clamping and cutting tools. As a reliable torsion spring for pruning shears and custom torsion spring for clippers, it adopts full CNC multi-axis integrated forming craft: one-step coiling spring coils, precise multi-angle bending for dual torsion arms and end hook feet. We equip standardized heat setting tempering, tip chamfer polishing plus electro-bright passivation to deliver smooth, corrosion-resistant surface. Manufactured by professional custom torsion spring manufacturer, all dimensions and torsion force can be fully adjusted via OEM custom service to match different clipper, shear and mechanical clip assembly requirements for hardware tool factories worldwide.

• Torsion spring for pruning shears, garden branch cutting hand shears
• Custom torsion spring for clippers: hair clippers, pet grooming clippers
• Handheld manual clamping tools, plastic pipe clamps, fixture clips
• Agricultural garden trimming tools, orchard fruit picking shears
• Household hardware pliers, multi-function hand cutting tools
• Small mechanical equipment rebound and clamping torsion components
• Industrial assembly spring fasteners for consumer hardware accessories

As a dedicated custom torsion spring manufacturer, comprehensive OEM custom service is offered for all v shape torsion spring and stainless steel torsion spring with hook ends:

• Custom production from customer CAD drawings, technical specs or physical sample parts
• Adjustable wire diameter, coil OD, coil turns, torsion arm length and hook bending angle
• Custom V-shape angle, hook tip radian to fit unique shear & clipper housing
• Material grade customization: 304, 316 stainless steel per corrosion resistance needs
• Tailored torsion force output to meet different tool rebound clamping strength
• Custom electro-polish, matte passivation or other surface finish options
• Small trial batch & mass bulk order support for hardware tool brand clients

• 316 stainless steel + bright passivation finish, resists rust from garden moisture & hair chemical liquid, avoids early spring failure.
• Standardized heat setting tempering eliminates forming internal stress, prevents fatigue breakage after millions of shear opening/closing cycles.
• CNC multi-axis precision bending with tip chamfer polishing, no sharp burrs to scratch tool housing or user hands during assembly.
• Tight ±0.04mm dimensional tolerance, hook arm position perfectly aligns shear/clipper assembly slots without fitting mismatch.
• Stable ±7% torsion force consistency, uniform rebound elasticity, no weak clamping after long-term frequent use.
• Integrated one-piece coiling & bending construction, no weak welding joints, longer service life than split assembled torsion springs.
• Full OEM custom service, no limit on non-standard sizes, solve difficulty of finding matching torsion spring for special tool models.

• Raw material incoming inspection: 316 stainless steel wire composition, tensile strength and straightness testing.
• In-line real-time dimension monitoring during CNC coiling and multi-axis bending processing.
• Post-forming deburring and full visual inspection to eliminate sharp edges.
• Standardized high-temperature heat tempering stress relief process with fixed time & temperature control.
• Batch electrolytic polishing and bright passivation anti-rust corrosion resistance test.
• 100% torsion force testing for every production batch to guarantee elastic consistency.
• Precision micrometer sorting to filter all out-of-tolerance double arm torsion springs.
• Final appearance scratch inspection before dust-proof packaging.

• Can you make custom torsion spring for clippers and pruning shears from our samples or drawings?
  Yes, as a custom torsion spring manufacturer, we provide full OEM custom service based on your physical samples or CAD technical drawings.
• What material options are available for stainless steel torsion spring with hook ends?
  Standard material is anti-corrosion 316 stainless steel; 304 stainless steel can be customized upon your requirements.
• How do you keep steady elasticity of this v shape torsion spring for long-term tool use?
  We apply professional heat tempering treatment and carry out 100% torsion force testing for each batch with ±7% precision tolerance.
• What is your MOQ for OEM custom double arm torsion spring orders?
  We accept small trial orders for new hardware tool buyers, minimum quantity can be negotiated for custom specifications.
• Does bright passivation surface effectively prevent rust for garden pruning shear applications?
  Electrolytic polishing plus bright passivation greatly improves anti-corrosion performance, suitable for humid outdoor garden working environment.
