M3 x 16mm (50 Pack) Socket Head Cap Screws Bolts, 304 Stainless Steel 18-8, Allen Socket Drive, Full Thread, Bright Finish, with Hex Spanner

High quality worked well

I love socket head caps for my speaker builds. They give a nice industrial, "exposed ductwork/pipes" aesthetic. M3's are perfect for speakers and securing the various components. I got these in 30mm sizing for attaching a speaker riser I 3D printed. These felt quality. Tolerances were tight, the threading and hex heads held fast. These are a good value, definitely recommend.

The HEXPHANT M3x12mm screw set are fine, functional stainless screws. I did get 50 screws and the appropriate hex key in a securely closing plastic box. The hex key fits the bolts fairly well with some variance in play (but never an amount that feels like too much play). I think for the price you are getting a good value. They are not the screws photographed in the listing. They are not A2-70 bolts, and they are not as crisply machined as the bolts in the photos. But that doesn't make them bad, just not as represented. Edges are rounder, knurling a little more variable, thread at the end of the bolt a little less crisp. To be fair it's probably a photo of a larger bolt that would have more detailed machining. But they fit into nuts and heat set inserts as designed, and are certainly functional fasteners. At just over six dollars for fifty, I think this is a good value for a set of stainless bolts.

More shiny M3x10mm socket head screws. The dimensions of the screws match the listed dimensions, like they should. Includes an allen key. They don't have the size imprinted on the socket cap like some of the images show in the listing. Not a big deal but good to know. They look like stainless steel, but I don't have a way to verify that for certain. I haven't had any of them strip out or cam out when using them. They are good quality, couple of them had some minor burrs, but not enough to cause trouble. They are priced competitively for their quality level.

Very nice screws. Good these to use on my bicycles. Manufacturing quality optically looks outstanding, bolt heads and thread look flawless and excellent. Of course I do not have equipment to test strength and even if I had, don't know what strength I had to look for for stainless bolts. I use these on Raspberry Pi projects and for small custom sheet metal brackets for my bike like installing a light to my basket and for my rain barrel yard watering system etc.. These come in a pretty solid plastic box for storage with a proper lid and sufficient strength and even include an Allen wrench, though I have this size on my multi-tool as well. A complete package - love it.

High-quality Socket Head Cap Screws Bolts, 304 Stainless Steel 18-8, These are able to be deployed with a Allen Socket Drive, Full Thread, mechanism. The cost for the money is impeccable. And these are better quality than finding local hardware stores or big box hardware stores These include a Bright Finish, with Hex Spanner These are clearly engineered for heavy-duty use I found that these can be used for furniture fastening (chairs, workbenches), these include use in mechanical industries, automotive repairs, and marine applications. These are designed with 304 stainless steel resists deformation and withstands high-pressure environments These are rust resistant and ensuring long-lasting performance.

These are standard quality M3x30mm screws with a socket head, the most common type of hardware used in 3D-printed designs. The dimensions all match what the standards say they should be. The 30mm length is used as hinge hardware for some of the post popular 3D-printed rugged box designs, and I can say they work perfectly for that. With a 50 pack you'll have enough for quite a few boxes, too!

I ordered these M3 by 50 socket head cap screw bolts to attach pneumatic fittings I’m using on a project in my Jeep. M3 bolts fit perfectly in 1/4 inch NPT push to connect fittings. These bolts are high-quality and nuts thread onto them easily. The case snaps shut solidly with no danger of them opening and spilling everywhere. The stainless steel bolts look great and will look good in my application. These bolts will impress you and others as well. At only $7.99 (at the time of this review) this is a bargain for 30 fasteners. You can’t even touch that at the big box hardware store. If you are shopping around for some good M3x50 socket head cap screw bolts then I can highly recommend these.
