M20 x 25mm 杯頭內六角止付螺絲 | 18/8 不鏽鋼 (50顆/包)

I've been hunting for M20 set screws that won't strip under torque, and the hex socket drive on these makes adjustment in tight spots a breeze. The cup point grips the shaft securely, and the 18/8 stainless finish looks clean and resists rust so far. Pack of 50 is plenty for my project, too.

The cup point bites into the shaft firmly, so the M20 screws hold their position even under vibration. The 18/8 stainless feels solid and the hex drive let me torque them down precisely without stripping. Exactly what I needed for the machine guard.

The hex socket drive made it easy to torque these down in a cramped spot under the conveyor frame, even with gloves on. The cup point bit into the shaft nicely and hasn't budged since, and the stainless finish looks clean against the steel.
