Yes. They are designed for standard metric coarse threads from M3 to M12. As long as your bolt or screw matches one of these sizes, the thread will engage smoothly.
Brass offers better electrical conductivity and a warm golden finish โ great for electronics projects or decorative hardware. Stainless steel provides superior rust and corrosion resistance, making it the go-to choice for outdoor, marine, or damp environments.
No tools are required for normal hand tightening. The wide butterfly wings are specifically designed to be turned by hand. If you need extra torque for a permanent installation, you can use pliers, but hand force is usually enough.
They are available in multi-piece packs that cover the most popular sizes (M3โM12). Check the current listing variation for exact piece counts and size assortments. Bolts and screws are not included โ you receive only the wing nuts.
Absolutely. Woodworkers use them for jigs and adjustable stops, and the M3โM8 sizes are especially popular on 3D printers for bed leveling knobs and quick-change fixtures. Just match the thread size to your hardware.
