Parafusos de cabeça sextavada M20-1.5 x 55 mm | Aço classe 10.9 zincado | Roscado total (25 / Embalagem)

Installed a set of these on a heavy-duty jig I'm building, and the Class 10.9 strength gives me real confidence they won't strip under load. The fully threaded design was perfect for getting a solid grip in a deep tapped hole.

The zinc plating looks clean and even across all twenty-five, and the fully threaded length saved me from having to stack washers on a tight machinery mount. Class 10.9 rating gives me confidence these won’t stretch under load. Wrench fit was snug right out of the bag, no stripped hex heads.

Had to swap out some old bolts on a large conveyor frame; these M20-1.5 screws threaded in smoothly with no binding. The zinc plating on the hex heads looks clean and hasn't shown any rust after a few weeks of factory use.
