What you want is good clamping force .. a function of the correct torque of the fastener. Spreading the same force over a broader area doesnt affect the tightness of the bolt at all, and gives more uniform clamping. The smaller area does equate to more concentrated force [higher psi] .. same force over smaller area. This is very seldom a good thing for the clamped pieces.I would think more surface = less PSI so the fastener wouldn't be as tight.
