براغي رأس مقبس M4-0.7 × 12 مم | رأس زر بمحرك سداسي المقبس | ملولب بالكامل | فولاذ مقاوم للصدأ 316 (600 / عبوة)

Priced right for the quantity, these M4 button heads are fully threaded and the 316 stainless finish looks clean under my shop light. I used them on a jig and they seated deep without stripping, so I'm set for a while.

I finally replaced the cheap machine screws with these 316 stainless ones—the hex socket drive is a huge time-saver compared to slotted heads. They fit perfectly in my precision assemblies and the threads are clean right out of the package.

Bought these for a batch of jigs and fixtures, and the 316 stainless is reassuringly tough—no rust worries even in a slightly damp shop. The button heads sit flush enough for most of my setups, and a full box of 600 means I won't have to reorder for a long while.
