Custom Locking and Sealing Screws | Your Solution for Vibration & Leaks

Struggling with fasteners loosening under vibration or leaks compromising your product’s integrity in harsh environments? Our custom-engineered screws combine robust self-locking action and reliable sealing performance into a single, elegant solution.

One Fastener, Dual Protection: Anti-Vibration & Waterproof Sealing

We integrate two critical technologies into one fastener through a precision manufacturing process:

Reliable Locking: IFI 524 Compliant

A resilient nylon patch is fused to the threads, creating powerful frictional resistance to self-loosening caused by intense vibration. It’s not only effective but also reusable, making it ideal for access panels and serviceable components.

Superior Sealing: IP-Rated Against Water, Oil & Air

A pre-installed silicone O-ring under the head compresses upon tightening to form a 360-degree airtight and watertight seal. It achieves an IPV5 rating as standard, and can be designed to meet a demanding IPV7 rating for full water immersion, while also preventing oil and gas leakage.

Versatile Applications Across Industries

Our sealing screws are trusted in industries where reliability is non-negotiable:

Automotive Electronics & Engines (Oil resistant, high-temp, anti-vibration)

Outdoor Communication Gear & Lighting (IP67 waterproof, UV resistant)

Medical Devices & Scientific Instruments (Clean, high-purity sealing)

Drones & UAVs (Lightweight, vibration-proof)

Industrial Machinery & Hydraulic Systems (High-pressure sealing, oil-proof)
