M6-1 X 16mm キャップスクリュー | 皿穴付き六角穴付き | 全ねじ | 18/8 ステンレス鋼 (400 / パック)

Used a whole box of these on a custom jig build and every single screw threaded cleanly into tapped holes with no binding. The hex socket drive feels precise and the stainless finish looks great against the aluminum. Exactly what I needed for a solid, repeatable assembly.

Installed these on a precision assembly fixture and the hex socket drive made tightening in tight spots much easier than a Phillips head would have. All 400 screws had clean, burr-free threads right out of the bag.

Used a full box of these on a custom jig this week, and not a single stripped head or burr on the threads. They seat cleanly in the hex socket even with a worn Allen key, and the 18/8 stainless gives me confidence they’ll hold up in damp shop air.
