Panhead Screw for Bachmann HO 33” EOT Device BAC42907

Bachmann manufactures an HO EOT device shown in Fig 1 that works quite well.

Not to mention the fact that it is half the price of the other popular EOT device currently available on the market. The author found it on eBay for around $20.00. 
There is one problem with it however. Notice in figure 1 that the mounting hole is larger than a normal 2-56 mounting screw. Yes, that's right, it takes a somewhat special screw to mount it properly. On some of the forums there has been discussion of using washers along with 2-56 screws but this can lead to coupler height issues.

So, after some research the author found the correct panhead screw to use to mount this EOT. See Fig 2.

Bachmann parts has it and it is hard to find but it is located here. They do not come in packs but are sold individually. You can order up to 20 of them. Bachmann takes all major credit cards along with PayPal.

No more washers or misadjusted couplers.
