iexcell 100 Pcs M4 x 20/25/30/35/40 Alloy Steel 10.9 Grade Hex Socket Button Head Cap Screws Bolts Assortment Kit, Black Oxide Finish

I use a lot of M5's of different lengths for my projects. I don't need the nuts, just the screws but that's OK. I can always use more nuts in my life. Good assortment of screws.

It has what it says it has. I would like to sit down and count every single bolt, but there are so many that I don't really care: it's more than enough for my projects.

The most important thing - they fit. Threads seem quite clean, material seems hard, coating coverage seems great. They work for my application. What else do you want?

A good assortment at a good price. Call me screwy, but I like them very much.

I don't expect M3 to hold up a car. So, relatively speaking these are fine. They are handy to have around. All the sizes and plenty of each size. A good value pack.

Covers lots of common sizes for 1/10 Scale RCs and is a great kit for custom builders.

Great fit. Great price.

I create a lot of droids and cosplay items and more times than not, the specs call for a specific M size.. this kit has been perfect in providing what i need.

**Sturdy Screws, All in One Place** I picked this set up for small home repairs and crafting, and it’s been pretty handy. The stainless steel screws feel strong and don’t rust, even when I used them outdoors. I like that there are five different sizes, so I don’t have to run to the store when I need a different length. The little hex key that comes with it is decent—it fits the screws well and doesn’t strip them. The storage box keeps everything neat, though the latch could be tighter. This would be great for anyone who likes fixing things around the house or doing DIY projects.

It contains a good quantity of the M3 sizes I use most 6,8, and10.
