How to Install Bollard Facing Pads with Counter-Bored Bolting

Overview

This guide covers the practical steps to install bollard facing pads with counter-bored bolting. JSLT Marine produces engineering plastic components in UHMWPE, HDPE, PA, POM and PTFE — full-process fabrication from raw sheet to CNC-machined parts.

Step-by-step procedure

1. Mark bolt positions. Transfer hole pattern from pad to bollard; check clearance.
2. Drill and tap bollard. Use stainless inserts for sea environment; depth = 1.5× bolt diameter.
3. Mount pad with washers. Mechanical fastening only; large washers spread load.
4. Torque progressively. Three-step torque pattern prevents pad warping.
5. Inspect after first storm. Re-torque any loose bolts; verify pad seating.
