Professional grade quality

As a hobbyist machinist, I am picky about fasteners. These have consistent head heights and precise threads. Will buy again.

Good value assortment

Nice variety of sizes in one pack. I used the M4 and M5 for assembling a computer stand. Only wish it came with a small Allen key.

Perfect fit for my CNC project

These screws are exactly what I needed. The threading is clean, and the hex socket doesn't strip easily. Great quality stainless steel.

Solid hardware

Very sturdy bolts. The polish is nice and smooth. Took off one star because the packaging was a bit flimsy, but the screws themselves are great.

Saved my repair job

Needed specific M3 lengths that local stores didn't carry. This kit had everything. Fast shipping and great product.

Excellent corrosion resistance

I used these for an outdoor garden fixture. After three months of rain, there is absolutely no rust. Highly recommended for outdoor use.

5 FAQ

Q: Is the head fully threaded or partially threaded?

A: These are fully threaded socket cap screws, providing maximum grip length for your applications.

Q: What is the length range included in this kit?

A: This specific assortment includes lengths ranging from 4mm to 20mm depending on the diameter selected. Please check the detailed size chart in the images.

Q: Do you sell replacement keys if I lose mine?

A: We do not sell the keys separately, but standard metric Allen keys available at any hardware store will fit these screws perfectly.

Q: Can these be used in saltwater environments?

A: While 304 stainless steel offers good corrosion resistance, for constant submersion in saltwater, we recommend 316 stainless steel for better protection.

Q: Are these screws compatible with imperial tools?

A: No, these are metric screws (M2-M12). You will need a metric hex key set to install them properly.
