Robert ★★★★★

I needed fully threaded bolts for a jig assembly and these M20s fit perfectly without any extra machining. The zinc coating looks clean and even, and they threaded smoothly into my pre-tapped holes.

The hex socket drive on these M20 screws grabbed my wrench perfectly without any slippage, and the zinc plating looks clean and durable. They threaded smoothly into my machine base with zero binding, exactly what I needed for a sturdy jig assembly.
