M12-1.75 x 45mm 內六角螺絲 | 內六角驅動 | 全牙 | 316不鏽鋼 (50個/包)

The hex drive took my Allen key perfectly without any slipping, which was a relief after fighting with cheaper bolts all afternoon. These 316 stainless screws are exactly what I needed for my outdoor jig project where rust resistance matters.

Used a few of these to rebuild a heavy-duty jig for the workshop, and the 316 stainless is holding up great in a damp garage without a speck of rust. Fully threaded along the whole 45mm length made alignment a lot easier than I expected.

The hex socket drive seats the Allen key perfectly with no wobble, and threading them into my jig fixture was smooth all the way down. These 316 stainless screws feel solid for marine-grade work, and the 45mm length was exactly what my assembly needed.
