Noix de capuchon en forme de dôme

Xiaoguo® Hexagon domed cap nuts are made from stainless steel that doesn’t rust, even in salty air or heat. They’re built to handle heavy loads and daily wear—use them on boats, factory machines, or outdoor gear. Need custom sizes? Xiaoguo® ships fast.

Product details and parameters

Use hexagon domed cap nuts anywhere bolts need extra protection. Farmers put them on tractors and plows to stop mud from jamming threads. Mechanics use them on truck axles or construction gear because they stay tight, even with constant vibration. At home, they’re great for fixing garden sheds or metal fences—no rusty bolt ends sticking out.  

Hexagon domed cap nuts are for industries where gear gets beat up daily. Shipyards slap the stainless steel ones onto dock cranes—they don’t care about salty sea air. Solar farms use the zinc-coated version on panel frames that face storms and wind. Factories? They throw these nuts onto conveyor belts and machines that never stop shaking. If your equipment works hard, these nuts keep bolts locked down.
