I need to drill and tap a hole. I dont think i can find a 3/8-24 tap around here. Any stores to look at?
If Sears, Home Depot, Lowe's or your local HW store doesn't carry them...use McMaster-Carr.
Sometimes your best bet is to try a machining supply store; if there is one in your area. Although, 3/8 being very common, should be found at homedepot (or whatever major chains you have in the USA) The tap you are looking for may also be called a 3/8" UNF (unified fine thread), and not labeled 24 tpi.
If its a captured bolt, you may need two taps to thread the full length of the bore: a plug tap and a bottoming tap.
I believe you also need a Q sized drill bit for that. You may wanna check that in a machinest handbook, its just off the top of my head. If not, you can probably go up to an 11/32" bit and loose a tiny bit of thread depth.
The tap set and tap& die set I have from Sears each has one.
I bought a set from Home Depot last year that has one.
ill just go raid the tap bin at work were bound to have one lol:rollin:
