Hobbyists, engineers, and workshop professionals who work with mechanical assemblies, jigs, or custom fixtures need springs that hold their rated dimensions under repeated load cycles without distorting or corroding prematurely.\u003c\/p\u003e\n\u003cp\u003eThese compression springs feature a 3.0mm wire diameter and are available in outer diameters of 26mm (~1.02 in) and 27mm (~1.06 in), with free lengths ranging from 20mm (~0.79 in) to 100mm (~3.94 in). Each pack contains 5 springs, giving you spares for prototyping or replacement. The springs are manufactured from steel wire with a consistent helical pitch and squared, ground ends for stable seating.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include return mechanisms in pneumatic and hydraulic valve assemblies, tension-relief components in custom jig and fixture builds, and replacement springs for industrial equipment maintenance where a 26–27mm OD small pressure spring is specified. The range of lengths makes these suitable for compression spring replacement in machinery, spring-loaded latches, and DIY mechanical projects requiring a 3mm wire diameter coil spring.\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\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Suitable for spring seats or bores designed for 26mm or 27mm outer diameter.
