Parafusos de cabeça sextavada M6-1 x 14 mm | Aço classe 10.9 liso | Roscado totalmente (3500/embalagem)

The hex head grabbed my socket wrench cleanly on every single one—no stripped corners across the whole box. Class 10.9 steel feels solid for the heavy equipment I’m bolting together. Glad I bought the bulk pack, saved me a trip to the hardware store.

Went through all 3,500 installing them on a production jig over two days and not a single stripped head or broken shaft. The 10.9 steel holds torque well when you're wrenching them down, and the hex drive sits deep enough that a socket doesn't slip.

The threads are cut clean and consistent from the first screw to the last, and the hex heads seat perfectly with a 6mm socket every time. I’ve got 3500 of them, so they’ll keep my assembly line running for months without a single reorder.
