So I purchased a STA that is Highland or XS Scuba. In the package there were 2 plastic washers (nylon?). What are these used for? Are they just a spacer? I remember something from school about dissimilar metals but didn't think it would apply (all 316 stainless I think) and can't really remember specifics. Also wondering about what delrin nuts to order that will fit the bolts that came with the STA.
Thanks.
Thanks.
