iexcell 1500 Pcs M3 x 4/6/8/10/12/16/20/25/30/35/40/45/50 Alloy Steel 12.9 Grade Hex Socket Head Cap Screws Bolts Nuts Washers Assortment Kit, Black Oxide Finish

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!

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.

Since most M3 assortments top out at 25 or 30 mm in length this is a nice complementary selection. The quality of the bolts is good enough for my purposes: assembling 3D printed models. I really like the case…it’s probably the best case of any of the many nuts/bolts/washers assortments I have sitting around. The dividers are built in, the lid is shaped to prevent bolts from visiting their neighbors, the latch is sturdy, and it’s tough plastic. The case is not made from brittle plastic…it survived an accidental drop test right after I got it.

Nice bolts and good value for the money but be aware if your going to use them in an automotive application like I did they will rust very quickly. This took about a month here in the south. Thankfully I had extras and I sprayed them down with clear lacquer first this time and that should slow it down quite a bit.

M4 and M3 are used a lot with 3d printed parts, as they are small and simple. They seem strong for how cheap they are. The Nut dimensions are correct for most downloadable files on thingaverse and printables.

Great fit, great price

These are socket cap M3 screws purchased for 3D printing projects. They have a satin black finish. The socket cap is 5.55mm outer diameter and 3mm tall (it has a slightly tapered bottom edge that is 5.30mm outer diameter and 0.5mm tall - inclusive of the 3mm overall height). The kit includes washers and nuts and it's a good assortment of sizes for common projects.

I needed some long 3.5mm screws for a project. These worked well.

I've had zero issues with these screws. Their dimensions are as advertised; they don't strip easily, thread nicely onto nuts, and hold well.

Lots of sizes and quality is good

Got the pieces i needed to finish the wing mount socket heads that snapped clean off my v5 Notorious...still holding strong first set out on few hard wnough wing landings

This kit is perfect for 3D printers. I bought it to have some longer lengths compared to another kit that only goes up to 20mm long. I would purchase again.

As described, arrived within the estimated shipping window
