Securpak Nylon Locking Nut ZP M12 Pack of 6

Product Overview

The Securpak Nylon Locking Nut ZP M12 is a heavy-duty fastener designed for applications where a secure, vibration-resistant connection is essential. Made from durable zinc-plated steel and featuring a nylon insert, this M12 locking nut is ideal for large-scale mechanical, construction, and automotive applications. The nylon insert creates a tight friction fit with the bolt threads, preventing loosening from movement or vibration.

This pack contains 6 high-strength M12 nuts, making it suitable for tasks that require a smaller quantity of industrial-grade fasteners without compromising on quality or performance.

Key Features and Benefits

Integrated Nylon Insert
The nylon component creates a friction grip on bolt threads, significantly reducing the risk of loosening due to vibration, torque, or repetitive motion.

Zinc-Plated Steel Construction
Provides good corrosion resistance for general use, extending the service life in dry or indoor environments.

M12 Metric Thread Size
Standard 12mm thread diameter, compatible with bolts, screws, or threaded rods of the same size.

Hexagonal Shape
The standard hex design ensures easy installation and removal using common tools like spanners, sockets, or impact wrenches.

Secure and Reliable Locking
Excellent for use in high-vibration environments where maintaining tightness is critical.

Pack of 6
Provides a cost-effective solution for heavy-duty DIY, repair, or assembly jobs.

Technical Specifications

Recommended Applications

Construction and scaffolding

Automotive repairs and modifications

Industrial machinery and equipment

Agricultural and mechanical assemblies

Heavy-duty DIY projects

Fixings in vibration-prone environments

Installation Notes

Always align the nut and bolt properly before tightening to prevent cross-threading.

Use appropriate torque to avoid stripping threads or damaging the nylon insert.

Not suitable for high-temperature applications (above 120C), as heat can degrade the nylon component.

Frequently Asked Questions (FAQ)

Q1: What is the nylon insert for?

The nylon insert acts as a locking feature that resists loosening from vibration or movement by gripping the threads of the bolt.

Q2: Can these nuts be reused?

They can be reused a limited number of times in non-critical applications. However, each use wears down the nylon, reducing its locking effectiveness. For structural or safety-critical applications, it is recommended to use a new nut.

Q3: Are these suitable for outdoor use?

The zinc plating provides moderate corrosion resistance, making them suitable for sheltered outdoor applications. For prolonged outdoor exposure or harsh environments, consider stainless steel variants.

Q4: What bolt size do these fit?

These are compatible with M12 bolts, screws, or threaded rods, which have a nominal diameter of 12mm.

Q5: Are tools required for installation?

Yes. A standard spanner or socket wrench is required. Power tools like impact drivers can be used for quick fastening in larger jobs.

Q6: Can they be used with washers?

Yes, flat washers can be used to distribute load or protect surfaces, though a locking washer is not necessary due to the nylon feature.

Q7: Do they work at high temperatures?

No. The nylon insert will soften or melt above approximately 120C, which can cause the nut to lose its locking ability. For high-heat applications, choose an all-metal lock nut.

Q8: Are they suitable for structural use?

Yes, for light to medium structural use in appropriate conditions. Always ensure compatibility with your applications load and environmental requirements.

Conclusion

The Securpak Nylon Locking Nut ZP M12 Pack of 6 is a dependable, heavy-duty fastener solution engineered for vibration resistance, durability, and ease of use. Its integrated nylon locking insert ensures a secure fit in demanding applications such as machinery, automotive, and construction. Whether for industrial repair, assembly, or robust DIY work, this compact pack of M12 locking nuts offers reliability and long-term performance.
