M20 x 25mm 滾花杯頭內六角止付螺絲 | 合金鋼 (50個/包)

Used these to replace cheap bolts on a jig fixture, and the hex socket drive let me torque them down properly without rounding off. The alloy steel feels solid, and the knurled cup point holds position way better than I expected.

The knurled cup point really digs in and holds firm, which is exactly what I needed for a stubborn alignment job. These M20 screws feel solid in the hand, and the 25mm length was perfect for my application.

The hex socket drive made torquing these down in a cramped spot way easier than I expected, and the alloy steel feels solid. Each one threaded cleanly without any galling, so the whole batch went in fast.
