M6-1 x 12mm 內六角螺絲 | 六角驅動 | 全螺紋 | 12.9級合金鋼鍍鋅 (400/包)

Had to swap out some cheap bolts on a milling fixture, and these M6-12s threaded in smooth and true with no binding. The hex socket drive took a good torquing without stripping.

The hex socket drive made these much easier to install in tight spots than standard hex bolts, saving me time on a jig build. For the price, getting 400 pieces with consistent threading is a solid deal for any toolbox.

Used a full bag of these on a jig setup last weekend and the zinc plating held up better than some pricier screws I've tried. The 12.9 alloy steel feels properly tough when torquing down, though I wish the threads were slightly cleaner out of the bag. Solid value for the quantity.
