Makers, hobbyists, and small-workshop engineers who need a dependable, drop-in replacement — or a purpose-built spring for a new design — will find exactly what they need here.\u003c\/p\u003e\n    \u003cp\u003eThese compression coil springs are wound from spring steel wire with a diameter of 1.5 mm (0.059 in). Three outer diameter options are available — 8 mm (0.315 in), 9 mm (0.354 in), and 14 mm (0.551 in) — and free lengths range from 10 mm to 120 mm (0.39 in to 4.72 in). Each spring is tightly wound with consistent pitch and squared, ground ends for stable seating.\u003c\/p\u003e\n    \u003cp\u003eTypical applications include compression spring replacements for 3D-printer extruder assemblies, return springs in custom CNC fixtures and toggle clamps, pressure elements in DIY pneumatic valve actuators, and load-bearing springs in small automation jigs and robotic end-effectors.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔧\u003c\/span\u003e\n    Compatible with standard spring pockets and bores sized for 8 mm, 9 mm, or 14 mm OD springs.
