براغي رأس كبس M12-1.75 × 70mm | محرك سداسي | ملولبة جزئيًا | فئة 12.9 سبائك فولاذ مطلية بالزنك (25/عبوة)

Used these on a custom jig at the shop and they torqued down smoothly without any stripping. The zinc plating looks even and the partial thread grabbed just right in the tapped hole. Solid pack for the price.

Threads were clean and the hex socket seated perfectly on my driver, no wobble at all. The zinc finish is even across all 25 pieces, and they torqued down nicely on my jig without any galling. Exactly what I needed for this fixture.

Needed a high-strength bolt for a fixture I was building in the shop, and these handled the clamping force without any issue. The partial threading was exactly what I needed to get the right grip depth.
