They use a 1/8th inch diameter, can't recall the depth. I bought a box of 500 at Grainger probably 15 years ago when part of weekly maintenance at my ghetto washes was replacing vacuum latches. I just used the last of them last week. My local Lowe's doesn't carry stainless but it looks like Amazon carries a 1/8" x 1/8" in small packs of 25. That may not be long enough.
