Parafusos de cabeça sextavada M36-4 x 80 mm | Aço liso classe 8.8 | Roscado completo (6 / Embalagem)

These bolts are fully threaded, which made tapping into existing steel frames much easier than I expected. The 8.8 class steel feels solid for the price, and the hex heads fit my socket wrench without any wobble.

The hex head is machined clean enough that a socket grips them tight without any wobble, which matters when you're torquing down on a refit. Fully threaded through the whole 80mm, so I didn't have to improvise with spacers. Solid set for the price, and the class 8.8 rating feels appropriately tough

The threads are cut clean for an 8.8 grade, so they torqued up without any binding or galling. Only knock is the 80mm length feels a bit short for some of my heavier flanges, but they're solid for general assembly work.
