M6-1 x 60mm 內六角圓頭螺絲 | 平頭內六角驅動 | 部分螺紋 | 10.9級合金鋼鍍鋅 (200入/包)

Finally found partially threaded M6s in this length, which is great for clamping applications where the smooth shank needs to pass through. The hex socket drive makes them easy to tighten in tight spots, and the zinc plating looks consistent across all 200 pieces. Perfect for the precision assembly

Bought these for a jig I’m building and the hex socket drive seated perfectly with my Allen key—no stripped heads on the first ten I installed. The 60mm length with partial threads gave me just enough grip for the clamping force I needed, and the zinc plating looks clean and even.

The partially threaded design on these was a game-changer for aligning my jig setup, and the zinc plating looks clean and durable. All 200 pieces came packaged securely with no defects, so they fit perfectly in the fixture plate.
