FDM vs SLA 3D printed bolts and nuts (PLA vs Resin)

What do you think, which is stronger? FDM printed (PLA) or SLA printed (Resin) bolt and screw nut? That’s what I am testing in this video. Strengh test of PLA bolt as most common material for FDM 3D printer and Water Washable Photopolymer resin. Since I don’t have SLA 3D printer, I used 3D printing service, I ordered resin M6x20 bolts and M6 nuts.
