M3.5 is a rare thread form in cap screw form and so available lengths and stock can be limited.
If you are looking for M3.5 cap screws for use in clearance holes together with M3.5 nuts, you may want to consider
No 6 UNC. The diameter is only nominally 0.005mm larger (1/5th of 1 thousandth of an inch) than metric M3.5 and the choice of lengths is wider. Our UNC HT cap screws are listed
here
*Please note that the 20mm & 50mm long M3.5 cap screws require a 2.8mm (7/64") key
