M30-3.5 X 100mm براغي ذات رأس سداسي | فئة 10.9 فولاذ عادي | ملولبة جزئياً (4 / عبوة)

These threads cut cleanly with a die, and the hex head grabbed a socket without any rounding. The partial threading is exactly right for cinching down a bracket while leaving a smooth shank for alignment. Solid batch, no burrs or rust spots out of the package.

I needed a partially threaded bolt for a heavy-duty jig, and these M30 hex heads handled the torque without stripping. The 100mm length gave just enough grip for my steel frame assembly.

These bolts fit perfectly in our press frame and the 10.9 grade gave me confidence for a high-torque application. The partial threading made alignment much easier than I expected.
