Re: Coupler Mounting Screws

I used the Kadee plastic screws when I first started building resin kits, and two negatives soon appeared. The first problem was that occasionally a screw would freeze and trying to remove it would strip the head, which required drilling a new hole, filling it with styrene and starting over. The second problem is that the Phillips head on the Kadee screws is large, requiring a #1 Phillips screwdriver instead of the #0 screwdriver I use for metal screws. That can be a problem in tight clearance situations. It’s really quite easy to strip the plastic head, as it’s not deep enough to properly engage the screwdriver tip. I use 1-56 pan Phillips metal machine screws from FMW Fasteners in  ¼ in., 3/16 in., and 5/32 in. lengths. I ordered 500 each online, and they should last a lifetime. These screws have a deep Philips head that perfectly fits a #0 screwdriver, and I’ve ever had one fail.

Tony,

 

That is how you cut longer bolts and treaded rod in the real world.  Always works.

Why I like the Delrin 2-56 screws is I can cut or trim them to the exact length that I want, with ease.  I've done this before and after installation with equal success.

 

      Works equally well with brass screws, Mont. Just turn a nut onto the screw above the cut, make the cut, then turn the nut back off, cleans up the thread, then file if needed. Almost as quick as with plastic.
