براغي ذات رأس أسطواني M16-2 × 70 مم | محرك سداسي برأس منخفض | ملولبة جزئيًا | فئة 8.8 من سبائك الصلب (75 / عبوة)

The low head profile clears tight spots where a standard cap screw would snag, and the hex socket grips the Allen key without any slip. Threaded portion makes alignment in jigs feel precise. Solid batch overall, no duds in the 75.

I was worried the partially threaded design wouldn't hold up under stress, but these M16 screws didn't budge on my jig fixture—solid Class 8.8 steel, and the low head profile made installation in tight spots much easier than expected.

The hex socket drive really helps with tight spaces where a regular wrench can't fit. These M16 screws fit perfectly into my jig setup, and the partial thread gives just the right hold without bottoming out. Solid Class 8.8 alloy steel feels tough enough for repeated adjustments.
