M3–M12 White Nylon Hex Bolts — Lightweight, Non-Conductive & Corrosion-Resistant Fasteners
When metal fasteners corrode, conduct electricity, or add unnecessary weight to your build, you need a smarter alternative. Engineers, hobbyists, and electronics assemblers working with PCBs, enclosures, and chemical-exposed assemblies rely on plastic fasteners to eliminate rust, galvanic corrosion, and electrical shorts — without sacrificing thread integrity.
These white nylon hex bolts are manufactured from PA66 polyamide to DIN 933 — the metric standard for fully threaded hexagon head bolts. Thread diameters span M3 through M12, with lengths ranging from 4mm to 100mm (0.16" to 3.94"). Each bolt features clean, precise metric threads and a standard hex head compatible with common wrenches and sockets.
Typical applications include electronics enclosure assembly, aquarium and wet-environment hardware, RC car and drone frames, chemical processing equipment, and decorative or display fixtures where a clean white finish is preferred. The non-magnetic, non-conductive properties also make these bolts well-suited for MRI-adjacent equipment and sensitive instrumentation.
🔩 Compatibility: DIN 933 metric thread profile — fits standard metric nuts, inserts, and threaded holes. Use with matching nylon nuts or metal nuts as required by your application.

❓ Frequently Asked Questions
What material are these hex bolts made from?
These bolts are made from PA66 nylon — a high-performance engineering plastic known for its mechanical strength, chemical resistance, and lightweight properties. PA66 is non-toxic, odorless, and antibacterial.
What sizes are available?
Thread diameters range from M3 to M12. Lengths typically range from 4mm to 100mm depending on the diameter selected. Use the Size dropdown above to select your specific diameter × length combination.
Are these bolts corrosion-resistant?
Yes. Nylon is inherently corrosion-resistant and will not rust, making it suitable for wet, chemical, or outdoor environments where metal fasteners may degrade over time.
Are these bolts electrically non-conductive?
Yes. PA66 nylon is an electrical insulator, making these bolts ideal for electronics, PCB assemblies, and applications requiring electrical isolation or non-magnetic properties.
What standard do these bolts conform to?
These bolts are manufactured to DIN 933 — the metric standard for fully threaded hexagon head bolts. This ensures compatibility with standard metric nuts, threaded inserts, and tooling.
How do I choose the right bolt length?
Measure the thickness of the material being fastened and add the depth of the nut or threaded hole. Generally, the bolt should extend at least 1–2 thread pitches beyond the nut for a secure hold. When in doubt, size up.
What quantity options are available?
