I used to use Viessmann 4178 as they had a phillips head and were easier to get out after a few years. |

A dot of caulk on both sides of the track, camouflaged with landscape material will do the same thing, without creating more noise through the tracks :) Works like a dream for me !! Tim

Part 7299 is no longer produced by Marklin. I have had success with 74990 though sometimes the holes in the M track are slightly too large.

M3 screws at 20mm or 25mm will do fine for M track.

7299's are available on eBay; what I don't like about them is they are slotted instead of Phillips; their small size and short length (2x15mm) can be quite fiddly even with a correct size flathead/slotted screwdriver. As Harvey said, the 74990's (1.6x13mm) are close and even though the newer versions have Phillips heads their heads are small for M-track holes (they're meant for C-track). 7599's for K-track are even smaller (1.4x10mm). M3's with a flat countersink head and Phillips slot may work but the head diameter may be large enough that it sticks up. Since the 7299's are M2 they may be better because they can set lower without overly distorting the trackbed.

I have mixed feelings about the 7299s. As noted, they are slotted instead of Philips (or "Reed and Prince" for you old-timers like me :) ). They are what I had on hand, so they are what I used. I found that using something (like a drill, nail set, or leather punch, etc.) to make a starter hole greatly assisted with getting the first couple of threads to catch. It never occurred to me that they might make things noisier. - MR Edited by user 24 April 2024 05:25:01(UTC)
