Good quality
Very useful to have on hand, they are high quality screws of decent stainless steel, they start easily with a very clean thread. My only small gripe is that they could do with more of the smaller lengths in the box or have a ratio that leans more to the shorter ones as I always end up running out of those first, that could just be me though lol.

Great set of M3 screws + bolts
A great bolt + screw set. I've used quite a few so far and they are dimensionally accurate and all fit together perfectly.Because they have been arranged in size order inside the box, the correct screw is always easy to locate and use.

Excellent value for money
These sets are very good value, the quality is good and a very good selection of sizes in sensible quantities. It's really cheaper to buy like this than to replenish in individual sizes
