براغي رأس أسطوانية M20 × 120 مم | محرك سداسي | فولاذ مقاوم للصدأ 18/8 (4 / عبوة)

Needed heavy-duty bolts for a press fixture, and the hex socket held up without stripping under high torque. The 18/8 stainless steel feels solid and hasn't shown any corrosion after a week of coolant spray.

Used them for a jig assembly on a milling machine and the 120mm length gave me just the right reach. The hex socket drive made tightening in tight spots so much easier than a button head would have.

Installed these on a custom tooling fixture and the 18/8 stainless held up perfectly under repeated torque. The hex socket drive gave me a clean, solid engagement without any cam-out.
