I agree with 'Doc, forget the hardware. However, I do use stainless (s/s) Eye and S hooks to attach the fiber lines to the metal brackets at both ends. This gives a smooth round surface without sharp edges that can cut. You probably don't want to make your guy lines real taut...as you would with wire or cable. In fact a little slack in the lines may be easier on the antenna, but don't let them get too loose. Get the mast straight, that's more important.
Another tip is to not let the bottom of these push up poles touch the ground, they rust badly in a short period of time in most soils. Ground the antenna with short ground straps or clamp the mast directly to a long ground rod. Just keep it above ground and attach with a couple of strong s/s muffler clamps. The bottom of the mast really needs to be secure. I set my P/Ur's up on a patio stone or something similar to keep it out of the dirt.
Just be careful, and watch for those power lines nearby.
