The bolts are straight, threads are clean, and the 60mm length is a nice sweet spot — long enough to pass through a printed part, washers, and nut with room to spare, without feeling absurdly oversized. The 304 stainless feels solid and inspires confidence when you’re spinning it with a drill; no sketchy flex or mystery-metal vibes. The included flat and spring washers are a nice bonus. Having everything in one kit made it easier to design the print around the actual stack height (bolt head + washer + part + washer + nut). For 3D printing specifically, the tolerances were consistent enough that I could model the holes for an M10 clearance fit and have everything line up without needing to ream or force it. Only downsides: the nuts are a bit chunky, so if you’re designing a compact part or recessing them into the print, you’ll want to account for their height and outer diameter. The washers are also pretty standard thickness — fine for most uses, but if you want a really wide load spread on plastic, you might end up upgrading to larger washers later. Overall, though, for a simple, sturdy, metric hardware set to pair with a 3D-printed drill attachment, this did exactly what I needed and made the mechanical side of the project pretty painless Review: Perfect buy - Perfect ## Features - 【SIZE】- Dimension: M8 x 20mm; Rod Length: 20mm / 0.79"; Hex Width: 13mm / 0.51"; Hex Thickness: 5.45mm / 0.21"; Pitch: 1.25mm / 0.05" - 【EXTERIOR】- Color: Silver Tone；unfinished surface - 【MATERIAL】- Made of 304 Stainless Steel which is superior to regular steel and any zinc plated fasteners, provides good strength and corrosion resistance in bad environments - 【APPLICATION】-The bolt will be more stable and fastened on the mechanism that rotates clockwise or shakes violently, good anti-loosening effect.
