براغي رأس مقبس M10-1.5 × 80 مم | محرك مقبس سداسي مسطح الرأس | ملولبة جزئياً | سبيكة فولاذ فئة 12.9 مطلي بالزنك (50 / عبوة)

Used these on a custom jig frame and the 12.9 alloy steel handled the torque like a champ—no stripping on the hex socket even after repeated tightening. The zinc plating is holding up nicely against light shop moisture, and the partial thread gave me just the right grip depth.

The partially threaded design made alignment quick when mounting a heavy jig base, and the zinc plating looks clean. These 12.9 alloy screws held up perfectly under the torque I needed for a precision assembly.

The hex socket drive on these M10 screws made installation much easier than I expected, and the partially threaded design is perfect for clamping down jigs securely. They're good quality for precision assemblies.
