M12-1.75 X 25mm 插座帽螺絲 | 低頭六角插座驅動 | 全螺紋 | 8.8 級合金鋼 (50 個/包)

These are perfect for mounting jigs on my milling machine; the low head profile gives me just the extra clearance I needed under the quill. The hex socket engages cleanly and the threads are consistent through all 50 pieces.

Needed some low-profile bolts for a tight jig setup, and these M12s with the hex socket drive fit perfectly without any clearance issues. The Class 8.8 alloy steel feels robust enough for regular machine adjustments.

Finally got around to swapping out the old bolts on my jig, and the fully threaded design on these made alignment much easier. The hex socket drive bit snugged them in tight without any stripping, and the 25mm length was perfect for the job.
