Compression and Extension Springs set NEO tools 200 pieces (MPN 11-980)

The NEO tools set of 200 compression and extension springs provides a broad assortment of small metal springs intended for mechanical repairs, prototyping and routine maintenance. This collection includes multiple diameters and lengths of both compression and extension types to cover common needs in locks, small machines, household appliances and hobby projects where varied spring sizes are required.

Advantages

The assortment delivers a wide range of sizes in one kit, reducing the need to source individual springs. Springs in the set are made of metal suitable for general-purpose use, offering consistent coil geometry for reliable mechanical behaviour. The combined presence of compression and extension springs allows flexible replacement and assembly options during repair, testing and prototyping tasks.

Suitable for

• Replacement of worn or damaged springs in locks and latches
• Repair and maintenance of small motors and appliances
• Prototyping and functional testing of mechanisms
• DIY projects, model making and electronics where spring force or return is needed

Key specifications

• Quantity: 200 springs in assorted sizes and types (compression and extension)
• Material: metal wire suitable for general mechanical use
• Types included: compression springs and extension springs
• Range: assortment covers multiple outer diameters and lengths for small-scale applications

How to use

Select a spring from the kit that matches the required outer diameter, free length and type (compression or extension) for your application. Verify fit and preload by comparing with the original component or by measuring required deflection and force. Install compression springs into housings or between components where they will be compressed under load; install extension springs by securing hooks or ends to the mating parts so they provide the intended tensile force. For prototypes, test different sizes from the set to determine optimal spring rate and travel before finalizing the design.

Usage recommendations

Inspect springs for straightness, uniform coils and absence of corrosion before use. Avoid exceeding the elastic limit by compressing or elongating springs beyond their usable range; repeated overloading shortens service life. Store the kit in a dry place to prevent surface oxidation and separate delicate components from heavier parts when transporting.
