براغي رأس أسطواني M22-2.5 × 120mm | محرك سداسي | ملولبة جزئيًا | فئة 12.9 من سبائك الصلب مطلية بالزنك (10 / عبوة)

I needed some high-strength fasteners for a custom jig, and these M22 socket caps fit perfectly. The partially threaded design grabbed just right, and the zinc plating should keep them from rusting in my shop.

The 12.9 alloy steel on these screws feels significantly tougher than the stuff I usually get for tooling jigs. The hex socket drive seated perfectly with my wrench, no stripping at all. Exactly what I needed for a heavy-duty fixture build.

The partial threading on these 120mm socket cap screws made alignment in my tooling jig much easier than using fully threaded bolts. They tightened down evenly with a hex key and the zinc coating looks clean and durable.
