M3-0.5 X 6mm ソケットキャップスクリュー | 六角ソケットドライブ | 全ねじ | クラス8.8合金鋼 亜鉛メッキ (800本/パック)

These are a solid deal at 800 pieces for the price, and the zinc plating looks uniform across the batch. I’ve used a good handful for installing brackets and haven't had a single stripped head yet, which is what matters with M3s.

Bought these for a jig I’m building and the hex socket drive is perfectly machined, no stripped heads even on the third install. The 800-count box will last me for years of prototype work, and the class 8.8 steel feels solid for the price.

The zinc plating on these M3 screws looks flawless, and the hex socket drive seated perfectly with my driver on the first try. I’ve used about 200 so far for jig assembly and not a single stripped head or burred thread. For 800 pieces at this price, they’re a solid value for any precision work.
