Stainless Steel Extended Leg Compression Spring with Customized Extended Legs and Precision CNC Coiling

The Extended Leg Compression Spring | Stainless Steel Custom Coil Spring is a precision-engineered spring that combines reliable compression force performance with customized extended leg structures for positioning, mounting, electrical contact, and assembly applications.

Unlike standard compression springs, this design features specially formed extended ends that provide enhanced installation support, improved positioning accuracy, and greater functional flexibility. The extended legs can be customized in length, angle, shape, and orientation to meet specific application requirements.

Manufactured from high-quality materials including stainless steel SUS304, SUS316, carbon steel, and music wire, these custom coil springs deliver excellent elasticity, corrosion resistance, fatigue resistance, and long service life. They are ideal for applications requiring repeated compression cycles, stable spring force, and reliable mechanical performance.

Precision manufacturing ensures accurate dimensions, consistent spring rate, and excellent durability. These extended leg compression springs are widely used in automotive components, electrical equipment, electronic devices, switches, battery assemblies, medical instruments, household appliances, and industrial machinery.
