M5 x 25mm 滾花杯端止付螺絲 | 合金鋼 (250/包)

The knurled cup point grips the shaft without slipping, even after I cranked it down hard with a hex key. All 250 screws came uniformly threaded with no burrs, and the alloy steel feels solid for the price.

The hex socket drive let me really torque these down in a tight spot where a regular wrench wouldn't fit. I was pleasantly surprised by the alloy steel quality for the price—they hold firm without stripping.

The knurled grip on these makes a real difference when you're torquing them down in a tight spot—no slipping even with oily fingers. All 250 arrived clean and the hex sockets are cut sharp, so my Allen key seated firmly every time.
