براغي رأس مقبس M3-0.5 × 30 مم | رأس مسطح سداسي | ملولبة بالكامل | ستانلس ستيل 18/8 (800 / عبوة)

I've been using these for mounting brackets on my CNC machine, and the full threading along the entire 30mm length makes them grip securely even in thin material. The hex socket drive handled my driver without stripping, which is a relief.

These fit perfectly in my 3D printer's linear rail mounts. The hex socket grabs the Allen key securely without any rounding, and the stainless steel feels solid.

I needed a bulk pack of M3 screws for a CNC build, and these 18/8 stainless steel ones hold perfectly without any burrs in the threads. The flat head sits flush in the aluminum plate, and 800 pieces should last me through several projects.
