Low Crown Acorn Nuts

Low Crown Acorn Seal Nuts

Secure Your Fasteners

ZaGO’s low crown acorn sealing nuts are used by industry and military engineers to protect the integrity of their fasteners. When leakage due to vibration, pressure, and environmental forces are a concern, experts agree that ZaGO’s low crown acorn sealing nuts yield the best results. Our low crown acorn sealing nuts look like ordinary low crown acorn nuts on the external side, but on the inner side, they alone feature a rubber fixture, permanently fused to their threading, which allows them to form a virtually unbreakable seal when torqued.

ZaGO manufactures highly durable and visually aesthetic low crown acorn sealing nuts that are compatible with every type of environment. In addition, our low crown acorn sealing nuts function perfectly with any surface material. No preparation, no cleanup and no maintenance is ever required with our low crown acorn nuts. Like all ZaGO products, the low crown acorn nuts retain their qualities for years and can be reused multiple times. We use several combinations of rubber and steel to manufacture the nuts, and can customize them based on your needs.

Sealing fasteners from every direction in metal-to-metal contact, ZaGO’s pre-assembled low crown acorn sealing nuts are built to the highest standards needed for devices exposed to pressure or contaminants. ZaGO’s low crown acorn sealing nuts will outperform any other competing nuts and will protect your equipment so that it can perform at its best.
