براغي تثبيت بنقطة كوب M4 × 16 مم | فولاذ مقاوم للصدأ 18/8 (500 / عبوة)

Had to swap out some stripped set screws on a piece of machinery, and these M4s fit the hex socket perfectly without any wobble. The cup point really digs in firmly, giving me confidence they won't back out under vibration. Solid batch of 500 for the price.

These things are tiny, but the hex socket drive grips perfectly even with my smallest allen key, which makes adjusting them in tight spots a total breeze. I’ve used about a hundred so far on a project and not a single one has stripped.

The 18/8 stainless steel feels solid and corrosion-resistant, and the cup point tip sits flush against the surface perfectly. I've used a few dozen already for mounting brackets in tight spots, and they grab securely without stripping.
