براغي رأس أسطواني M20-2.5 × 65 مم | محرك سداسي داخلي | ملولبة بالكامل | فولاذ سبائكي درجة 8.8 مطلي بالزنك (25 قطعة/عبوة)

Torqued these down for a heavy-duty tooling fixture and the hex socket drive held up perfectly under high torque without stripping. The zinc plating on the alloy steel seems like it will resist rust well in my shop.

Used them to bolt down a jig fixture on my mill table and the 8.8 alloy steel held torque without a hint of stripping. The zinc plating looks clean and uniform across all 25 pieces, which is more than I can say for some cheaper packs I've tried. These are my new go-to for anything needing a solid M2

I needed these for a machinery jig build, and the hex socket drive made installation much easier than standard bolts. The fully threaded design gave me a solid, secure hold, and the zinc plating looks like it'll hold up well.
