🔒 Zinc Plated Flanged Nyloc Nuts – Flange Nylon Insert Locking Nuts M5 to M12 | DIN6926
🏷️ Brand: HomeDIYer Fastener | DIN6926 | Class 8 Steel | Bright Zinc Plated (BZP)
📌 Overview — Integrated flange + nylon locking – one nut, zero washers, maximum vibration resistance. Tired of assembling separate flat washers, lock washers, and standard nuts? Our Zinc Plated Flanged Nyloc Nuts (DIN6926) combine a wide load-distributing flange with a reliable nylon insert locking mechanism. The flange eliminates the need for a separate washer, while the nylon ring grips the bolt threads to prevent loosening from shock and vibration. Made from Class 8 steel with bright zinc plating, these nuts offer good corrosion resistance for indoor and protected outdoor applications. Perfect for automotive assemblies, machinery, furniture, and any project where vibration is a concern. Available in metric coarse threads M5 to M12 – order the exact quantity you need.
✨ Key Features of Flanged Nyloc Lock Nuts (Zinc Plated)
-
Integrated Wide Flange – Eliminates the need for separate flat washers; distributes clamping load evenly and protects the work surface.
-
Nylon Insert Locking Mechanism – The nylon ring deforms around the male thread, providing consistent prevailing torque that resists loosening from vibration.
-
Class 8 Steel (Grade 8.8 equivalent) – High strength for general industrial and automotive use (tensile strength approx. 800 MPa).
-
Bright Zinc Plated (BZP) Finish – Offers good corrosion resistance for indoor and light outdoor use. Attractive shiny silver appearance.
-
DIN6926 Standard – Precision metric dimensions for reliable fit with standard coarse thread bolts.
-
Metric Coarse Threads M5–M12 – Covers common sizes for machinery, automotive, and structural applications.
-
No Separate Washer Needed – Faster assembly, lower parts count, and reduced inventory costs.

💡 Ordering & packaging: “As per Your Choice” – select the exact thread size and quantity you need. No mixed packs unless requested. These nuts are fully compatible with standard metric coarse bolts (e.g., ISO metric 6g threads).
🔧 Corrosion note: Bright zinc plating provides moderate protection against rust – ideal for indoor machinery, automotive under-hood (dry), and sheltered outdoor use. For marine or high-humidity environments, consider stainless steel (A2 or A4) flanged Nyloc nuts.
❓ Frequently Asked Questions – Flanged Nyloc Locking Nuts
Do I need a washer with these flanged nuts?
🔧 No. The wide flange replaces a standard flat washer, distributing load and protecting the work surface. This saves time, reduces parts, and prevents washer loss. For extremely soft materials (e.g., thin plastic), you may still add a backup washer, but it's rarely necessary.
How does the nylon insert locking work? Can I reuse these nuts?
🔄 The nylon ring compresses against the bolt threads, creating friction (prevailing torque) that resists loosening from vibration. These nuts can be reused several times – the nylon recovers partially. For safety-critical or high-vibration applications, replace with new nuts after 5-10 cycles. For general DIY, reuse is fine.
What is the temperature range for these nuts?
🌡️ The nylon insert is rated for continuous use from -40°F to +250°F (-40°C to +120°C). Above 250°F, the nylon may soften and lose locking ability. The steel and zinc plating handle higher temperatures, but the insert is the limiting factor.
Are these nuts compatible with any metric bolt?
📏 Yes, they use standard metric coarse threads (M5x0.8, M6x1.0, M8x1.25, M10x1.5, M12x1.75). They fit any bolt or threaded rod with the same thread pitch. Do not use with fine-thread bolts – match the pitch.
Will the zinc plating rust over time?
⚡ Bright zinc plating offers good corrosion resistance but is not as durable as stainless steel or hot-dip galvanizing. In dry indoor environments, it lasts for years. In damp or outdoor conditions, white rust (zinc oxidation) may eventually appear, followed by red rust. For outdoor use, we recommend stainless steel or a heavier coating.
