Product Description

Product Warranty:

（1）Warranty Eligibility & Claim Reporting

Our Metric Prevailing Torque Type Hexagon Flange Nuts meet standard size and performance requirements when used properly.If you discover obvious quality issues within the warranty period, such as mismatched threads, damaged flanges, or poor torque retention, you can contact us with order information and photos of the defective products for verification.

（2）Warranty Coverage & Exclusions

We provide a basic quality warranty for our industrial fasteners under normal use and standard working conditions.The warranty covers defects in material, thread processing, and overall structure, which are inspected during production and before shipping.It does not cover damage caused by incorrect installation, overloading, improper storage, or harsh corrosive environments beyond normal industrial use.

（3）Claim Handling & Extra Requirements

Once we confirm the problem is a manufacturing defect, we will send replacements or provide a reasonable solution based on the actual situation.Buyers must keep original packaging and order records for all warranty claims.This warranty applies to actual quality defects, not normal wear from long-term use.We process claims efficiently to avoid delays to your daily production and assembly.

Q&A Session：

Q: Can these Metric Prevailing Torque Type Hexagon Flange Nuts be reused after disassembly?

A: They can be reused for 2-3 times under normal disassembly conditions, as the locking performance comes from metal thread structure instead of plastic parts. Repeated disassembly may slightly reduce the locking torque, but it still meets basic daily use standards. We suggest avoiding frequent forced disassembly to keep stable performance, and replace them if the locking effect drops obviously after multiple uses.

Product Anti-loosening and Wear Resistance Performance：

（1）Anti-Loosening Performance

This fastener relies on its built-in prevailing torque structure to stay fixed in place during daily use. It creates stable friction between the internal threads and matching bolts, which stops the nut from loosening on its own even when used on equipment with regular vibration. It doesn’t need extra lock washers or thread locking glue to work, making it suitable for mechanical assembly, automotive parts, and automated production lines that run for long hours. The locking effect stays consistent under normal working loads, no obvious weakening after repeated installation and disassembly.

（2）Wear Resistance Performance

Metric Prevailing Torque Type Hexagon Flange Nuts have good basic wear resistance for daily industrial use. The thread surfaces are processed smoothly and evenly, reducing friction damage when matching with bolts during installation. The integrated flange spreads pressure evenly, avoiding partial wear on the contact surface of connected parts. Made of standard industrial steel materials, the threads and flange edge don’t wear out easily under regular assembly and long-term use, keeping stable fitting and locking performance without frequent replacement due to excessive wear.
