Minor inconveniences securing a rotating tool with bolts (4,5)

'minor inconveniences' is the definition.
'flea bites' can be an answer for 'inconveniences' (flea bite is a kind of inconvenience). I am not sure about the 'minor' bit.

'securing a rotating tool with bolts' is the wordplay.
'securing' indicates putting letters inside.
'rotating tool' becomes 'bit' (bit is a kind of tool. I am not sure about the 'rotating' bit.).
'with' says to put letters next to each other.
'bolts' becomes 'flees' (I've seen this in another clue).
'a'+'bit'='abit'
'abit' going within 'flees' is 'FLEA-BITES'.

Can you help me to learn more?
