براغي رأس أسطواني M10 X 40mm | محرك سداسي داخلي | سبيكة فولاذ مطلية بالزنك الأصفر (1000 / عبوة)

Used these in a new jig I built for my mill and the hex socket drive made installation in tight spots easy. The zinc yellow finish looks consistent across the entire thousand pack. Very solid screws for the price.

Installing these into a steel fixture for a production line, the hex socket drive engaged perfectly without any stripping. The zinc yellow finish seems durable and consistent across all 1,000 pieces.

Used a full box to build a sturdy jig for my drill press and every single cap screw threaded in smoothly, no binding. The zinc yellow finish looks consistent across the batch and seems like it’ll resist rust well in the shop. Exactly what I needed for precision assemblies.
