M33-3.5 x 300mm 육각 머리 캡 나사 | 클래스 8.8 강철 무도금 | 부분 나사산 (8개/팩)

The partially threaded section made seating them in our jig frame a breeze, and the hex heads grabbed the socket cleanly without any rounding. These M33s are hefty but they torqued down exactly where we needed them for the assembly line.

The partially threaded design was perfect for our conveyor roller assembly, letting the threads grab just enough without binding. Each bolt seated cleanly with a 19mm socket, and the hex head held torque without rounding. A solid choice for industrial framing work.

Had to replace the bolts on a big press at work, and these class 8.8 screws fit the bill perfectly. The hex head made them easy to torque down with a socket, and the partially threaded shank gave just the right grip depth.
