Review: Good screws - High quality worked well
Review: Good quality socket head screws - 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.

### ⭐⭐⭐⭐⭐ Good screws

### ⭐⭐⭐⭐⭐ Good quality socket head screws

### ⭐⭐⭐⭐ Stainless bolts that work well in a nice little box
*by C***. on February 15, 2026*

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.
