304 STAINLESS STEEL — Manufactured from premium 304 stainless steel wire for excellent corrosion resistance, heat tolerance, and long-term durability. Outperforms music wire and carbon steel in harsh environments, making these springs suitable for both indoor and outdoor applications.
CLOSED-END DESIGN — Both ends of each compression spring are tightly closed for efficient force transfer, reduced risk of tangling, and stable, consistent performance under repeated loading and compression cycles.
18 SIZES AVAILABLE — Choose from 2 outer diameters (3mm / 0.12" and 5mm / 0.20") and 9 free lengths (5mm / 0.20" to 35mm / 1.38"), all with a consistent 0.5mm (0.02") wire diameter. Each spring features even coil spacing and a uniform helical shape for reliable, predictable force output.
WIDE-RANGE APPLICATIONS — Ideal for home appliances, motor equipment, electronics, automotive parts, DIY projects, hobby models, and industrial machinery. Common uses include valve assemblies, locking mechanisms, shock absorption, latch systems, and return springs in mechanical devices.
PACK OF 5 — Each order includes 5 precision-engineered compression springs in your selected size. Refer to the product images and variant options above to choose the exact specification for your repair, assembly, or prototyping needs.
