براغي تثبيت برأس مقبس مسننة M20 × 40 مم | فولاذ سبائكي (50 / عبوة)

The hex socket drive bites perfectly into my driver without slipping, even when I'm cranking down on a tight metal bracket. These M20 alloy steel screws are holding up way better than the cheap zinc ones I used before.

I needed a high-torque set screw for a tight-space adjustment on a jig I’m building, and these M20 x 40mm flat points with the hex socket drive fit perfectly. The alloy steel feels sturdy, and the hex drive held firm without rounding off during install. So far, exactly what I needed for the job.

The hex socket drive let me get these M20 screws really tight in a cramped spot without stripping. They feel solid and the 50-pack is great value for the price.
