براغي ذات رأس أسطواني M4-0.7 × 25 مم | محرك سداسي | ملولبة بالكامل | فولاد مقاوم للصدأ 18/8 (600 / عبوة)

Installing these on a custom jig and the hex socket drive made tightening them in tight spots so much easier. The 18/8 stainless feels solid and corrosion-resistant, perfect for outdoor machinery.

I needed 25mm length specifically for a jig build and these fit perfectly, no stripped heads on first use. The hex drive seats cleanly, which is a relief after fighting with cheaper socket screws.

Finally found some small hardware that doesn't strip when I torque it down. These M4 screws are fully threaded and the 18/8 stainless is completely rust-free after being in a damp jig for a month.
