براغي رأس مقبس M8 X 40mm | محرك مقبس سداسي | فولاد سبائكي (300/عبوة)

Used them for a jig I'm building and the hex socket drive bit in perfectly with my Allen key, no stripping even when I torqued them down hard. All 300 arrived in good shape, threads were clean and the alloy steel feels dense enough for real tooling work.

Used a dozen of these in a jig for a CNC fixture, and the hex socket drive made torquing them down quick and hassle-free. For the price of 300 pieces, the alloy steel feels solid and consistent across the batch.

These are exactly what I needed for my latest jig build. The hex socket drive made installation quick, and the alloy steel feels solid. Pack of 300 should last me through several projects.
