Ludwig used the 1/4" models before they went to the 5/16". Sounds like your kit is correct. You can find them on ebay or maybe someone here might have some. The wing nuts are conveniat. The hex nuts are easier to tighten better though.

I have some Ludwig 1/4" wing nuts that were from the angle adjusters of WFL type snare baskets. They are 1/4" x 20 thread and much larger than you can buy in a hardware store. They should work. Let me know how many you need.

That's the ones!

Thanks for the responses. I am looking for 2 to hold the toms on the rack.

Also the point about easier to tighten is a good on. One of my toms has a regular nut and not the long ones like the other nuts but the are easier to tighten than the wing nuts that are on the floor Tom legs and bass drum spurs. I am considering staying with nuts to hold the Tom but I would like to get the correct nut. All of the nuts on the kit fit a 7/16 wrench. I saw drum keys on eBay that were being sold at $50 to $80. Pretty expensive but there are also less expensive sockets but I don't know if they would fit the 1/4 inch nut or if it fits a 5/16 inch nut.
