Installation Notes

Best used with a spanner or socket wrench to ensure proper torque application.

Avoid over-tightening, as this may degrade the nylon insert and reduce locking effectiveness.

Not recommended for high-temperature environments or permanent structural connections.

Frequently Asked Questions (FAQ)

Q1: What does “ZP” stand for?

“ZP” stands for Zinc Plated. This finish offers basic protection against corrosion and rust for indoor and mildly damp environments.

Q2: Can these nuts be reused?

Yes, but with limitations. The nylon insert wears down after repeated use, so for critical or safety-related applications, always use a new nut.

Q3: Are these suitable for outdoor use?

They can be used in sheltered outdoor environments but are not ideal for continuous exposure to moisture or harsh weather. For full weather resistance, use stainless steel or galvanized alternatives.

Q4: What size bolts or screws are compatible with this nut?

These nuts are designed to fit M5 bolts, screws, or threaded rods, which have a 5mm diameter and metric thread.

Q5: Do I need washers with these nuts?

Not necessarily. The nylon locking feature removes the need for additional locking components, though flat washers may still be used to distribute load or protect surfaces.

Q6: Will these nuts loosen over time?

No, the nylon insert provides a locking action that helps prevent loosening caused by vibration or torque. However, over time or in harsh conditions, periodic inspection is advised.

Q7: Are these suitable for high-temperature applications?

No. Nylon inserts can melt or degrade at high temperatures (typically above 120°C). For high-heat environments, consider using all-metal lock nuts.

Conclusion

The Securpak Nylon Locking Nut ZP M5 Pack of 20 is a dependable choice for projects requiring secure and vibration-resistant fastening. With its zinc-plated finish and nylon locking insert, it ensures long-lasting performance in general assembly, repair, and light engineering tasks. An essential item for workshops, garages, toolkits, and anyone seeking reliable fixings for M5-threaded components.
