M5-0.8×12mm 六角ボルト | 316ステンレス鋼 | 全ねじ (400本/パック)

Finally, a set of small fasteners that don't feel like they'll strip the moment I torque them down. The hex head on these M5s gives a solid bite with a 4mm socket, and the 316 stainless feels reassuringly heavy for the size.

Used these to replace rusted hardware on a marine hatch, and the 316 stainless held up perfectly in the salt spray. The hex head gave my socket a solid bite without stripping, even at higher torque.

Got the full 400 in the box, and every single hex head is threaded cleanly to the end, so they grip nicely without any fumbling. I used them to reassemble a small milling fixture and they torqued down solid with a socket. Exactly what I needed for a decent price.
