Hi Phil
Afraid you fell for one of the oldest tricks in the :threads" book - Chasers are NOT taps. The latter cuts a thread and that is the reason you ended up with excess play. Conversely, a Chaser does NOT cut the thread - it reforms it
Of course you needto know what the thread is because BSF, Metric and UNF are not the same.For that you need an inexpensive thread guide tool
Attachment 180912Hare & Forbes should know better than to sell a tap & die kit without asking what you wantedto do with it.
