I am looking for suggestions on replacing my drain plugs on my Predator. It is going in a Barstool and the engine plate is mounted below the frame so the fore and aft movement is limited because of the drain plugs. They are a 10 X 1.25 thread. I want a button head allen to replace them but no one makes one that you can buy. I found a pack of 1,000..... Not happening. I can buy all the 10 x 1.5 thread button heads I want. I googled this and found a thread on a Machinist's forum that suggested drilling and taping for a 7/16 button head. What do you guys think or do you have another suggestion????? Of course the easiest thing would be to find the correct thread in a button head but it does not look promising.
I did a little research and the 10 MM bolt hole is .3977 and the 7/16 hole needs to be drilled .3906 to be taped. I am tempted to try it and see. But... and there always seems to be a but..... It is almost as hard to find a 7/16 button head as it is the 10 X 1.25 button head but you can find them.
