Review on HHIP 3601 0011 Transfer Screw for Easy Piece Transferring by Ralph Gerry

Purchase ok. The screws worked very well, but they are tall so you have to drive them pretty deep into the hole for an accurate transfer. The real issue I have is the case itself which is aluminum. If you screw them into tight holes, the aluminum socket may come loose. My purchase was a one hit deal and I had to drill through a couple of gears. I figured that would happen when I put them in because I need them for the stainless steel frame. No damage, no foul. I wouldn't recommend them for hollow frames, and don't set them too low or you'll have a hard time getting them out.
