Great quality stainless steel
I was worried about rust in our humid workshop, but these 304 stainless screws have held up beautifully. The fine threads provide excellent grip.

Perfect for precision machinery
These fine thread set screws are exactly what I needed for my lathe projects. The 12.9 grade hardness ensures they don't strip easily, and the hex socket fits perfectly.

Professional grade hardware
As a maintenance technician, I go through a lot of grub screws. These are consistently high quality with no defects in the threading or socket.

Good value, fast shipping
The assortment kit is very convenient. One size was slightly tight, but overall a solid purchase for the price. Delivery was quicker than expected.

Reliable for automotive use
Used these to secure pulleys on a custom engine build. They hold torque well and the headless design allows for a flush fit. Highly recommend.
Q: What size Allen key do I need for the M8 screws?
A: For the M8 fine thread set screws in this set, you will typically need a 4mm hex key.
Q: Can I buy individual sizes if I run out of one?
A: Currently, we sell this item as an assorted kit only. However, please contact our sales team for bulk orders of specific sizes.
Q: Are these screws suitable for outdoor applications?
A: Yes, being made of 304 Stainless Steel, they offer high corrosion resistance and are suitable for most outdoor environments.
Q: Does the 12.9 grade mean they are brittle?
A: While Grade 12.9 indicates very high tensile strength, proper installation within torque specifications prevents brittleness issues. They are designed for heavy-duty industrial use.

A: Yes, all screws in this kit follow the ISO metric fine thread pitch standards for their respective diameters.
