M6 x 8mm 平先六角穴付き止めねじ | 合金鋼 (1000本/パッケージ)

The hex socket drive grips the Allen key perfectly, so seating these in tight spots was a breeze. I’ve already burned through half the box on a fixture build and every one threaded clean without a single stripped head.

I needed a bunch of M6 flat point screws for a jig I'm building, and the hardened alloy steel feels solid compared to the cheap zinc ones. The hex socket drive is precise enough to crank them down with a hex key without rounding out the socket—exactly what I needed for tight spots.

In the tight space behind the timing pulley, the hex socket drive grabbed instantly and the flat point seated perfectly without walking. All 1000 pieces came with clean threads on every single one I’ve used so far.
