M10 x 20mm カップポイント六角穴付き止めねじ | 18/8 ステンレス鋼 (250 / パッケージ)

I’ve been using these for a repair that requires frequent adjustments, and the hex socket drive gives a really solid grip even in tight spots. The cup point holds firm without slipping—exactly what I needed for a metal framework project.

The hex socket drive really let me cinch these down tight in a cramped bracket without stripping the head. The 18/8 stainless finish looks clean and gives me confidence against corrosion in my outdoor gear.

I needed some set screws for a jig I’m building, and these M10 x 20mm stainless ones fit perfectly. The cup point grips the shaft securely without slipping, even after tightening with my hex key.
