M20 X 20mm 平頭止付螺絲 | 合金鋼 (50 / 包)

I needed a heavy-duty set screw for a machinery jig, and these M20 flat points seated perfectly without marring the shaft surface. The alloy steel feels really solid, and the hex drive let me torque them down tight in a cramped spot.

These little M20 set screws are exactly what I needed for a stubborn alignment job, and the hex socket drive made torquing them down in a cramped spot a breeze. All 50 came out of the package clean with sharp threads and no burrs. For the price, they are a solid deal.

The flat point tip holds perfectly in my machine's adjustment collars, not slipping like the cup point ones I used before. All 50 pieces came clean and threaded smoothly without any binding.
