M6-1 x 8mm 內六角螺絲 | 平頭內六角驅動 | 全螺紋 | 316不鏽鋼 (300顆/包)

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.
