M4 X 25mm 錐點止付螺絲 | 合金鋼 (100個/包)

The hex socket drive makes tightening these in tight spots a breeze, even with my stubby Allen key. All 100 arrived in perfect shape, and the cone point seated firmly against the shaft without slipping.

These cone point tips grip the shaft so much better than the flat ones I’ve used before, and the hex socket made seating them in a tight spot a lot less fiddly. The alloy steel feels solid in hand, and a hundred of them for this price is a fair deal.

Exactly what I needed for a tight spot where a regular hex key couldn't reach—the cone point grabs perfectly. These M4 x 25mm set screws feel solid and held firm under high torque without stripping.
