Re: Coupler Mounting Screws
Daniel A. Mitchell
The Allen “button-head” is typically similar to a Pan-head, but maybe just a tad thinner. One nice thing about them is that they are almost always blackened. They’re also a higher strength screw, but I can’t imagine that being a major factor in model railroading.toggle quoted messageShow quoted text
The one downside is that they are steel, and thus magnetic. This can cause problems with Kadee-type couplers. An alternative is to get Stainless-steel Allen heads screws ... these are minimally magnetic and have the same profile … they do need to be painted however.
