M6-1×8mm キャップスクリュー | フラットヘッド 六角穴付き | 全ねじ | 316ステンレス鋼 (300本/パッケージ)

The hex socket drive seats the Allen key perfectly with no wobble, and the fully threaded length made seating them in my jig a breeze. I’ve used cheaper packs before, but these 316 stainless screws feel noticeably sturdier and haven’t shown a single speck of rust after a few damp weeks in the shop.

Finally, a pack of 300 that actually holds up under repeated assembly—the 316 stainless finish hasn't shown a hint of corrosion after a week of damp workshop use. The hex socket bites cleanly with a standard 5mm key, no stripping at all.

Putting together a jig for a small run of parts and these M6 flat heads seated perfectly flush. The 316 stainless gives me confidence they won't rust, which was my main concern. Solid value for a hundred pieces.
