Full description & dimensions for small size thumbscrew resonator fixing set with captive thread


"T" plate - 47mm wide approx x 21mm deep at the widest part; the 2 holes in the widest part are approx 5mm diameter and are spaced at approx 36mm centres - this gives some room for manoeuvre when the hook spacing isn't exactly right. The deeper part of the "T" is approx 17mm wide and has a 10mm long x 4.5mm wide slot about 3.5mm in from the outside edge through which the thumbscrew passes.


Wall lugs - these are 10mm hexagonal section approx 11mm long; the tapped (M4 x 0.7 pitch) hole is slightly closer to the outer end than to the resonator rim wall. The wall lug has an M4 x 0.7 pitch stud which screws into a captive thread (supplied) which has to be installed into the resonator rim wall. The captive thread is approx 9.5mm long (but can be shortened) and requires a mounting hole approx 6mm (always check the size of pilot hole on a piece of waste wood first - mahogany can be a great deal softer than maple). The wall lugs can be installed using just the M4 x 0.7 pitch stud if preferred.


Thumbscrews - these are approx 30mm long. The head is 12mm long x 10mm diameter at its widest part; the threaded section is approx 18mm long x 4mm diameter. The thread is M4 x 0.7 pitch and runs nicely in the wall lugs provided. These thumbscrews will fit any other type of wall lug with the same (M4 x 0.7) pitch - but it's useful to note that many of the older Far Eastern wall lugs are M4 x 0.75 pitch, so they won't fit even though they look as though they ought to .......


The finish is nickel - it's more satin than shiny as supplied but the parts will buff up quite a lot if required.
