iexcell 50 Pcs M4 x 20/25/30/35/40 Alloy Steel 12.9 Grade Hex Socket Head Cap Screws Bolts Assortment Kit, Black Oxide Finish

Nice

Generally Chinese fasteners are of vegetable quality but these seem to have fairly tight tolerances and are well machine. They even came coded with a bit of oil to prevent rusting.

For the price of a dozen screws at a local hardware store, I have a selection of 50 and even included an allen wrench!!

ok

Okay, just to let you know WHY I purchased these. I needed some M3 x 10mm hex head screws to use on my Burris Fastfire III Reflex sight that I was putting on my Walther PPQ Q5 Match gun - as the gun came with 3 mounting plates to mount different optics on it - however they didn't send it with the longer length screws (2) that I needed to put it on with!!! WTH? Anyways, since having extra screws around, especially ones that can come in really handy in the future with other guns and/or gun builds that might be done in our household, for less than $9 it was worth picking these up.Anyway, these are inexpensive but I did NOT have any problems with them. After figuring out which ones I needed I grabbed that bag (each size were individually packed in their own bags), opened it and pulled two screws out, grabbed the Doctor mounting plate, put it on with the original screws provided, added the Burris and put some blue loctite on the new hex head screws and mounted the reflex sight with no problem. Very, very happy. May get with my local gun shop friend/owner and let him know I have these screws if he should ever need any for future projects he has to do! : )Very happy!

No issues at all

If you’re buying these to do the gimbal spring mod on the Flysky NV14 Nirvana transmitter, they will work but with a couple caveats. First the thread pitch is different, but you’re also screwing into plastic so this screw will cut it’s own threads. Take it slowly and it shouldn’t damage the spring adjuster. This works out great in the end because these screws have a finer pitch, so they’ll let you make finer tension adjustments on the springs.The second caveat is that the screw heads are a LOT bigger than the screws you remove, so they will rub slightly on the edge of the circuit board on the backs of the gimbals. I used a small diamond file that came with one of my mini quad frames to file the edge of the board slightly so the screw head would clear it (about 1/32”).This mod makes a huge difference in stick feel, and now I can throttle up without turning, and turn without throttling.

These are nicely machined bolts for my purposes. And, an interesting first use for me.I had purchased a VESA Adapter for my Apple Cinema HD monitor on an online auction site, but the seller did not include the bolts needed to mount the adapter to the monitor itself. Because I had two mounts and two monitors I was able to use one of the standard Apple bolts in each, and I found that the 4Mx35mm bolt in this set fits perfectly.You can estimate my cost to complete the installation at US$5 per monitor if I had tossed away the other 98 bolts, or you could accept the true cost of US$0.10 per monitor because the remaining 98 bolts are in my fastener cabinet.Decent quality, affordable price, quick delivery, gets the job done.Please note that my photo of the package of bolts shows the standard Apple 4M screw key (wrench) for size comparison, and that key is not included with the bolts. I also included an image of both the standard and stylish Apple bolt and the functional and stylish iExcell bolt for comparison.

Excellent - Recommend
