Hello, i am using solidworks simulation static study,

i have 2 parts connected with 4 bolts and washers for both sides like it shows in pictures below : 

i made a bolt connector, i selected both edge for washers and i used Bolt series to selects both faces for part 1 & 2

i made a contact set with no penetration between part 1 and 2 

Do i need to add more contact set between washer and part1 and washer and part 2 ?

Also do all steps that i made using bolt connector are right ?
