Smarter connections
for the future of mobility.
Vehicles are becoming more complex, technologies are evolving rapidly, and safety and reliability are critical. Nedschroef delivers innovative sealing and insulation fasteners that go beyond fastening: they protect, insulate, and accelerate production.

Essential for safety, durability & functionality
Sealing and insulation are no longer add-ons. They are essential elements of modern vehicle design — and Nedschroef builds them directly into the fastener.
Seal
Protect against moisture, dirt, and liquids — from body-in-white joints to battery housings — with integrated washers, self-sealing nuts, and polyamide or polyolefin coatings.
Insulate
Prevent leaking currents and malfunctions in electrified vehicles through overmolding, insulating coatings (Eloxal / anodizing), and multi-material washers.
Accelerate
Integrate sealing, insulation, and fastening in one part — fewer components, fewer assembly steps, lower EHPV, and higher first-time quality.

What it is
Sealing & Insulation from Nedschroef integrates protection, functionality, and performance into one smart connection — sealing against water, dirt and liquids, and insulating against leaking currents.
Our Technical Toolbox
We don't push one technology — we deliver the best solution for your application. All designs are tested and validated according to automotive standards.
- Polyamide & polyolefin coatings
- Integrated washers
- Self-sealing nuts
- Thread coatings (e.g. Precote)
- Overmolding
- Insulating coatings (Eloxal / anodizing)
- Multi-material washers
- Synthetic and rubber solutions
Battery housing protection
An EV manufacturer came to Nedschroef with a challenge: a standard nut design failed to properly seal a battery housing under real-world conditions.
- A custom nylon washer integrated into the flange for surface sealing
- A specialized Precote coating on the thread area for additional protection
- Cost-effective, hydrogen-compatible — a critical requirement for modern batteries
"The combination of precise engineering and cost-effective design improved both our production efficiency and product reliability."
Applications
- Body-in-white connections
- EV powertrains
- Battery housings and packs
- Interior systems
- Cooling systems
- Busbars and electrical components
- Sensors and electronics
