براغي رأس مقبس M4-0.7 × 35 مم | محرك سداسي | ملولبة جزئيًا | فولاذ مقاوم للصدأ 18/8 (400 / عبوة)

Needed a batch of clean, consistent fasteners for a precision assembly rig, and these M4s fit the bill perfectly. The hex socket drive gripped securely without any stripping, and the 18/8 stainless steel finish looks great.

The hex socket drive fits my Allen key perfectly, and the partially threaded shaft made alignment in my fixture much easier. These 18/8 stainless screws feel solid and haven't shown any rust after a week in a damp shop.

Installed these on a jig I was building for a small CNC project, and the 18/8 stainless is holding up nicely so far. The partially threaded shaft made it much easier to align the parts before torquing them down. Only wish they came in a smaller quantity since 400 is a lot for a hobbyist.
