براغي رأس كبس M4-0.7 × 60 مم | مقبس سداسي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 18/8 (200/عبوة)

Installed these in a custom fixture and the hex socket drive gripped perfectly without stripping. The partial threading gives you plenty of clearance for stacking plates. Exactly what I needed for metal tooling work.

The 60mm length is perfect for my jigs where I need extra reach, and the hex socket drive grips firmly without stripping even under repeated tightening. The 18/8 stainless finish also hasn't shown a speck of rust after a few weeks in a damp shop, which is a pleasant surprise for the price.

Used a batch to mount some aluminum brackets on a CNC mill, and the 60mm length was perfect for reaching through thick stock. The hex socket drove cleanly without stripping, and the stainless finish hasn't shown any rust after a few days in a humid shop.
