براغي رأس سداسي M12-1.25 X 45mm | فولاذ فئة 8.8 عادي | ملولب جزئيًا (100 / عبوة)

Picked up a box for a shop jig I'm building, and the partial threads are perfect for blind holes where you don't want the shank bottoming out. The hex heads grab cleanly with a socket, and every one threaded smoothly without any galling.

Used these to bolt down a conveyor mount on a steel frame, and the class 8.8 steel held torque perfectly without any stretching. The partial threading made alignment a lot easier than full-thread bolts.

The hex heads seated cleanly with a 19mm socket and the partial threading grabbed just right for a tight flange joint. These are solidly built for the price, and a hundred in the package covers a whole project without a trip back to the hardware store.
