At the following website, 

Rfcafe.com

There is a great deal of info re the dielectric constant of various materials. 
Nylon varies from 2 to 5 depending on its composition. It is less than many 
other common insulating materials including porcelain. PFTE is very low.

At our lower frequencies, say below 100 MHz, I would not be concerned about 
using nylon hardware.
