About This Product
These Hillman set screws are simple but super useful little fasteners.
They're M4 size with a 0.

70mm thread pitch and 6mm length, made from stainless steel so they resist rust and corrosion.

They're headless, meaning they're fully threaded with no cap sticking out – you tighten them with an Allen wrench.

The idea is they pass through a threaded hole in one part and press against another part to lock it in place.
Common uses include securing pulleys, gears, or handles onto shafts.

This 10-pack gives you plenty of spares.
They come from a trusted brand, Hillman, and are made in the USA.
Small, sturdy, and reliable.
If you do any mechanical work or repairs, having these on hand is a smart move.

They won't strip easily and hold tight.

Good quality for the price.
