Cash received for making safety fasteners? (8)

'received for making safety fasteners?' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'cash' is the wordplay.
I cannot quite understand how this works, but
'cash' could be 'money' (cash is a type of money) and 'money' is found within the answer.
The remaining letters 'pin' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...

Can you help me to learn more?
