Good quality, fast shipping

Solid steel construction. I used the M10 size for a project and it held up well under vibration. Would buy again.

Nice assortment

Having multiple sizes in one pack is very convenient. The M12 screws were exactly what I needed for my lathe.

Perfect for machinery repair

These set screws fit perfectly in our industrial equipment. The fine thread provides excellent grip without stripping the hole.

Reliable Grade 4.8 strength

We use these for non-critical structural fixes in our workshop. The black oxide coating helps prevent minor rust.

Exactly as described

The hex socket is deep enough for standard keys, and the flat end sits flush. Great value for the quantity provided.
