Key Features and Benefits

Integrated Nylon Insert
The built-in nylon collar increases friction on the bolt threads, effectively preventing self-loosening caused by vibration or movement.

Zinc Plated Steel Construction
Offers a clean appearance and moderate corrosion resistance for general indoor use and sheltered environments.

Metric M4 Thread
Standard 4mm internal thread diameter compatible with M4 screws, bolts, or threaded rods.

Hexagonal Nut Shape
Easy to grip and tighten using standard hand tools such as spanners, sockets, or adjustable wrenches.

Reusable for Light Applications
Can be reused a few times in non-critical settings, though the nylon insert will degrade with repeated use.

Convenient Bulk Pack
Supplied in a pack of 30, perfect for stocking your workshop, toolbox, or maintenance supplies.

Installation Guidelines

Use a wrench or socket to apply even torque.

Do not overtighten—excessive torque can damage the nylon insert.

These nuts are not suitable for high-temperature environments (above 120°C), as the nylon may melt or degrade.

Frequently Asked Questions (FAQ)

Q1: What is the purpose of the nylon insert?

The nylon insert acts as a locking mechanism, gripping the threads of the bolt or screw to resist loosening caused by vibration or movement.

Q2: Can these be reused?

Yes, for non-critical applications, the nuts can be reused a few times. However, each use wears down the nylon, reducing its locking ability. For safety-critical or load-bearing uses, always use a new nut.

Q3: Are these nuts suitable for outdoor use?

They offer moderate corrosion resistance and can be used outdoors if sheltered. However, for exposed or marine environments, stainless steel or fully galvanized nuts are recommended.

Q4: What bolt size are these nuts compatible with?

These nuts are specifically designed for use with M4 bolts, screws, or threaded rods, which have a 4mm diameter and standard metric thread.

Q5: Do I need to use a washer with these nuts?

Not necessarily. The nylon locking feature often removes the need for lock washers. However, flat washers can still be used to protect surfaces or distribute load more evenly.

Q6: Will these work in high-heat environments?

No. The nylon insert is heat-sensitive and may deform at temperatures over 120°C. Use all-metal locking nuts for high-heat applications.

Q7: Are these suitable for electrical or electronic work?

Yes, the small size and secure fit make them ideal for light-duty electronic assemblies and device enclosures where vibration might be an issue.

Conclusion

The Securpak Nylon Locking Nut ZP M4 Pack of 30 is a dependable and efficient solution for light-duty fastening tasks where vibration resistance and a secure grip are essential. Designed for compatibility with standard M4 bolts, its zinc-plated finish offers modest corrosion protection, while the nylon insert ensures a long-lasting, vibration-proof connection.
