براغي رأس أسطواني بمقبس سداسي 3/4-10 X 4" | رأس مسطح بمحرك مقبس سداسي | فولاذ سبائكي مطلي بالزنك (20/عبوة)

Got a heavy jig table set up, and these 3/4-10 x 4" socket cap screws threaded in perfectly without any wobble. The alloy steel feels solid and the zinc plating looks like it'll resist rust well. Exactly what I needed for a precision assembly.

The hex socket drive made torquing these down into my jig plate so much easier than a slotted head—no cam-out, even at full depth. They’re dead-straight shanks and the zinc coating looks clean, no flaking after a week of shop use. Exactly what I needed for a stubborn 4-inch fixture build.

The zinc plating on these screws is holding up perfectly in my damp basement workshop, and the hex socket drive made them easy to tighten even in tight spots. Exactly what I needed for assembling some heavy-duty shelving.
