M5-0.8 X 50mm 凹頭螺絲 | 圓柱頭六角驅動 | 全螺紋 | 12.9級合金鋼鍍鋅 (200入/包)

Picked up a pack for a custom tooling fixture and the 50mm length was exactly what I needed to reach through a thick bracket. The hex socket drive made installation effortless with no stripping, even when torquing them down. Zinc plating looks clean and should hold up fine in my dry workshop.

Finally got these for my jig builds and the hex socket drive fits my Allen key perfectly. The 12.9 alloy steel feels solid and the full threading down the 50mm length made installation a breeze.

For the price, the zinc plating is surprisingly even and the threads are clean with no burrs. Used them to bolt down a jig plate and all 200 seated perfectly with a torque wrench.
