Nylon Insert Nut Installation and Removal Tips
2025-09-01
Welcome to Haiyan Bolt’s comprehensive guide on the installation and removal of nylon insert nuts. As a trusted manufacturer and supplier with decades of experience in the fastener industry, we understand the importance of proper handling to maximize the performance and lifespan of these specialized components. In this article, we will explore the key features and benefits of nylon insert nuts, provide detailed product specifications, and share professional tips for correct installation and safe removal. Whether you are in automotive, aerospace, machinery, or DIY projects, this guide will help you achieve reliable, vibration-resistant fastening solutions.
Nylon insert nuts, also known as nyloc nuts, are prevailing torque nuts with a nylon collar insert that provides resistance to vibration and loosening. The elastic deformation of the nylon material creates friction against the bolt threads, ensuring a secure hold even in high-stress environments. This makes them ideal for applications where safety and durability are critical.
At Haiyan Bolt, we pride ourselves on producing high-quality nylon insert nuts that meet international standards. Our products are manufactured using premium materials and undergo rigorous quality checks to ensure consistency and reliability.

Installation Tips
Proper installation is crucial for optimal performance. Follow these steps to ensure a secure fit:
-
Inspect Components: Check the bolt and nut for damage or debris. Ensure the nylon ring is intact and clean.
-
Alignment: Align the nut perpendicularly to the bolt axis to avoid cross-threading.
-
Hand-Start: Thread the nut manually until the nylon insert engages. This prevents damaging the threads.
-
Tool Selection: Use a calibrated torque wrench for accuracy. Avoid impact tools unless specified.
-
Torque Application: Apply steady torque until the nut is fully seated. Do not exceed the recommended torque value to avoid stripping.
Recommended torque values for our nylon insert nuts (based on medium carbon steel):
| Size (M) | Torque (Nm) | Torque (lb-ft) |
|---|---|---|
| M4 | 3.5 | 2.6 |
| M6 | 9.0 | 6.6 |
| M8 | 19.0 | 14.0 |
| M10 | 36.0 | 26.5 |
| M12 | 63.0 | 46.5 |
| Size (Inch) | Torque (lb-ft) | Torque (Nm) |
|---|---|---|

| 5/16" | 10.0 | 13.6 |
| 3/8" | 17.0 | 23.0 |
| 1/2" | 40.0 | 54.2 |
| 5/8" | 75.0 | 101.7 |
Removal Tips
Removing nylon insert nuts requires care to maintain reusability:
-
Clean Threads: Remove dirt or corrosion that might hinder rotation.
-
Use Correct Tools: Select a wrench that fits snugly to avoid rounding the edges.
-
Steady Pressure: Apply counter-clockwise force evenly. If resistance is high, slightly back off and retry to prevent thread damage.
-
Inspect After Removal: Check the nylon ring for wear. Replace the nut if the insert is deformed or damaged.
Common Mistakes to Avoid
-
Over-torquing, which can crush the nylon insert
-
Using damaged or worn bolts
-
Reusing nuts beyond the recommended limit
-
Exposing standard nylon to temperatures beyond its range
