Product Description
Rigging Hardware That Doesn't Quit on the Water
KAP Components stainless steel U-bolts and U-screws are purpose-built for marine, boat, and sailing environments where standard fasteners corrode fast. Every U-bolt is formed from 316 or 304 stainless steel, giving you a fastener that's genuinely high-strength and lightweight, without the rust bloom you get from lower-grade hardware.
The universal profile fits most boats, marine equipment, sailing rigs, and yachts, so it drops into rail mounts, stanchion bases, exhaust clamps, and deck hardware without custom machining. Each U-bolt ships complete with a matched mounting plate and two hex nuts, ready to install.
Whether you're rebuilding deck hardware after a season offshore or fitting out a new build, this is the fastener you install once and forget about — built to hold its finish long after mild-steel alternatives have streaked and seized. Proudly stocked and shipped Australia-wide from our Victoria warehouse.
- Marine-Grade Material316 and 304 stainless steel construction resists salt water corrosion far beyond zinc or galvanized hardware.
- High Strength, Low WeightSolid-formed U-bolt body holds rated load without adding unnecessary weight to rigging.
- Universal FitSized to suit most boats, sailboats, marine equipment and yachts without custom fabrication.
- Complete Hardware SetEvery unit includes the U-bolt, backing plate, and two hex nuts — nothing extra to source.
- Won't Rust or PitPassivated stainless finish resists the rust streaking and pitting common with lower-grade fasteners.
