براغي ذات رأس أسطواني من الفولاذ المقاوم للصدأ 18/8 من هولو-كروم 78118 1/2-13 × 1-3/4 بوصة | محرك سداسي | (50 / عبوة)

The drive socket on these is surprisingly crisp, so my hex key seated fully without any wobble when I torqued them down on my fixture plates. All fifty of them threaded in smooth and consistent, which is what I really care about for precision assemblies.

Replaced the old bolts on my milling jig with these 18/8 stainless cap screws and the socket drive seats perfectly, no wobble even after torquing them down hard. The 1/2-13 threads cut clean and the 1-3/4" length was exactly right for my setup, so I’ve got 48 left for the next project.

The hex socket drive fit my torque wrench perfectly, no stripping or wobble during assembly. These 18/8 stainless steel fasteners feel solid and corrosion-resistant for outdoor machinery use.
