3/4-16 x 2-3/4 英吋六角頭螺絲 | 美國製造 | L9級合金鋼 黃鋅 | 部分螺紋 (20入/包)

The yellow zinc coating on these screws has a nice even finish, and the hex heads seated perfectly in my socket without slipping. They’re holding up well so far in a heavy-duty frame assembly I’m building.

The threading on these is clean and the yellow zinc finish looks solid—no burrs or flaking out of the bag. I torqued one into a jig fixture and it seated perfectly without binding, and the partial thread gave just the right grip for the application.

Used these to secure a heavy press at work—the partial thread made alignment much easier than fully threaded bolts. Grade L9 holds up perfectly under high torque without stripping.
