براغي رأس أسطوانية HOLO-KROME 78012 #4-40 X 3/8" | محرك سداسي | ستانلس ستيل 18/8 (100 / عبوة)

I needed these for a small jig I was building, and the hex socket drive made installation a breeze with my T-handle wrench. The 18/8 stainless steel feels solid and corrosion-resistant, perfect for precision assemblies.

Finally, a batch of #4-40 screws that actually holds torque without stripping—the hex socket drive makes a huge difference when tightening inside a tight fixture. These 18/8 stainless ones are definitely tougher than the cheap zinc-plated stuff I've been fighting with.

Used these in a small robotics jig I was building, and the hex socket drove cleanly without stripping. The 18/8 stainless finish gives them a nice, uniform look compared to cheaper zinc-plated ones I've used before.
