براغي ذات رأس أسطواني M5 X 40mm | محرك سداسي | فولاذ سبائكي (400/عبوة)

The hex socket drive on these M5 screws grips the Allen key perfectly without slipping, which made installing them into my jig frame much smoother than with cheaper fasteners. The alloy steel feels sturdy and the 400-count box will last me through several projects.

Put these in a jig build this week and the hex socket drive bit engagement is perfect — tight, no wobble. At 400 pieces for this price, they're a solid buy for anyone doing repeated fixture setups.

I was worried about stripping these screws during assembly, but the alloy steel feels really strong and the hex socket engaged perfectly every time. The 400 count is great for keeping my jigs stocked without reordering soon.
