WELLOCKS Socket Cap Screw 251 PCS M4 Metric Bolts and Nuts Assortment Kit with Hex Wrench Button Head Stainless Steel 304 with Storage Box for Shelf Chair Desk Install Repair(D152)

This set of M4 socket cap head screws is very handy to have around, if like me you run a CNC machine or 3D printer then this set is essential as M4 seems to be a very popular bolt size on these machines.In this kit there are bolts are varying lengths, they are 5-6-8-12-16-20-25mm and all have an Allen key socket head, an Allen key is also supplied in the kit. There are also M4 nuts supplied in this kit too.The quality of these nuts and bolts seem fine and the M4 thread is smooth without burrs, the nuts are equally as good.This kit is supplied in a plastic case that can be hung up if required.Nice little kit to have around.

No burrs on any so far and dont strip easy. came in handy for my 3d prints.

I really like this wellocks set of button head bolts, you get a good mix of different length bolts to suit a variety of tasks. You never know when you might need a random length M4 bolt for a quick repair on short notice for things like 3D printers. If you're not 100% sure what size bolts you need for a project then these mixed sets are pretty good value rather than buying a big box of a single size and hoping for the best.It comes in the typical compartmented plastic box with a hinged locking clip, the lid has a clearly written list of the quantities each piece of the kit on the inside and outside. You get an allen key with the kit so you aren’t stuck if you don't own an appropriately sized bit or hex driver available.All of the listed quantities are accurate and they are all well formed without sharp burrs etc, I can't find a bad piece in this kit. The only slight complaint I have is that this kit is a little overpriced compared to similar products but the bolts are strong and I can't find any issue with the actual product except for the aforementioned price.No issues recommending this.

The set is really handy and with a great selection different size bots that are pretty strong for any mainstream use and the price at £12.99 is surely good. But it would have won a further star if instead of an allen key they would have provided a bunch of washers that personally I would have found far more useful

Nice selection of bolts with nuts.On delivery the items in the box had mixed up completely. I think a stronger hold on the box for transportation would be in order. Normally I wouldn't mid too much but every tried to tell the difference between 5mm and a 6mm bolt? really tricky.The selection is good but I don't really understand why you would need a 5mm and a 6mm id much prefer a 30mm or something quite different.Bolts are of good quality, metal is solid and doesn't deform when you over tighten them.

I do some hobby 3D printing and electronics as well as some amature garage mechanic work. These little M4 bolts are right in the sweet spot for me, where theyre large for my 3D printing jobs (little droids etc), and they're small for my car work.The quality of them is great and the different lengths give many options for different thicknesses of substrate etc.Really happy with this set and glad I got the chance to try them out, I would definitely recommend

They are listed as M4, and after a bit of checking with the old micrometer, the samples I chose were all machined well. Plenty of different lengths, but I'd not recommend for general DIY use as you'd probably need larger diameter ones for more heavy duty stuff. I like the fact the advert has a picture of a screw with a cross-head on it :-S I hex bolts as a rule, as even if you ruin it in some way, you can saw out a little notch on each side and use a flat head. All in all, you get a lot of bolts, and so the price of around £12 is fair. You may need different widths though, so great that in mind.

This set of socket-cap M4 screws and nuts is good value and a handy kit to have about. It conveniently comes with an allen key to tighten the screws, so if you don't have many tools in the house but you need to replace some M4 screws, then this kit works great. It would have been nice to have some M4 washers included with the kit but other than that, it's great.
