براغي رأس أسطواني M6 × 90 مم | محرك سداسي داخلي | فولاذ سبائكي (200 / عبوة)

The hex socket drive makes these easy to tighten even in tight spaces, and the alloy steel feels sturdy for my machinery projects. I used a full pack on a custom tooling setup and every screw seated perfectly.

The 90mm length was perfect for the jig I'm building—no more digging through mixed bins for the right size. All 200 arrived clean and threaded smoothly into my tapped holes without any binding. Definitely stocking up on these again for future machinery projects.

Installed these in a custom jig today and the 90mm length was exactly what I needed for the thicker plates. The hex socket drive held up well under torque without any stripping.
