A flush capped bolt system for attaching a plastic liner to a substrate includes a cap with a radial sealing skirt that seals against the walls of a counterbored recess at the liner surface. In the preferred embodiment, a squared portion on the bolt shank deforms a liner opening to provide a nonrotatable engagement, and there is a plastic wear washer to accommodate lateral movement allowed by an oversized substrate opening. The system is readily adapted for field installation using conventional tools.
