1. Introduction
This manual provides essential information for the proper use and understanding of the Vertex 3903-1269 M24 X 3 Flanged Nut. This component is designed for secure fastening applications, featuring an integrated flanged base for improved load distribution and stability. It is manufactured from heat-treated, case-hardened steel with a black oxide finish for durability and corrosion resistance.
Key Features:
- Heat treated steel construction: Ensures enhanced strength and resilience.
- Black oxide finish: Provides corrosion resistance and a non-reflective surface.
- Case hardened: Increases surface hardness for improved wear resistance.
- Integrated flange: Distributes clamping force over a larger area, reducing the need for a separate washer and minimizing material damage.
- Manufactured in Taiwan: Adheres to established quality standards.
2. Product Overview
The Vertex 3903-1269 is an M24 x 3 flanged nut. Its design incorporates a wide circular flange at one end, which functions as an integrated washer. This flange helps to distribute the load over a larger surface area, reducing the chance of damage to the fastened material and providing a more secure hold. The nut features internal threading designed to mate with an M24 x 3 threaded bolt or stud.

3. Setup and Installation
Proper installation of the flanged nut is crucial for ensuring a secure and reliable fastening. Follow these general guidelines:
- Preparation: Ensure that the mating bolt or stud has an M24 x 3 thread and is clean and free from debris, rust, or damage. The surface where the flange will rest should also be clean, flat, and free of obstructions.
- Alignment: Align the flanged nut squarely with the threaded bolt or stud. Begin threading by hand to ensure proper engagement and prevent cross-threading. The nut should turn smoothly without excessive force.
- Tightening: Once hand-tight, use an appropriate wrench or socket to tighten the nut. Apply torque gradually and evenly. The integrated flange eliminates the need for a separate washer, as it provides sufficient bearing surface.
- Torque Specification: Always refer to the equipment manufacturer's recommended torque specifications for the specific application. Over-tightening can strip threads, deform components, or cause material failure, while under-tightening can lead to loosening and assembly failure.
- Inspection: After tightening, visually inspect the nut to ensure it is seated flush against the surface and that no threads are exposed beyond the nut, if applicable to the design.
4. Operating Instructions
The Vertex 3903-1269 flanged nut functions as a secure fastener once installed. Its primary role is to hold components together under tension, distributing the load effectively due to its integrated flange. No specific operational steps are required beyond proper installation and periodic inspection to ensure continued secure fastening.
5. Maintenance
To ensure the longevity and continued performance of the flanged nut and the assembly it secures, consider the following maintenance practices:
- Regular Inspection: Periodically check the nut and the fastened assembly for any signs of loosening, corrosion, thread damage, or deformation.
- Cleaning: Keep the nut and surrounding area clean from dirt, grease, and other contaminants that could affect its performance or lead to accelerated corrosion.
- Re-tightening: If any loosening is detected during inspection, re-tighten the nut to the appropriate torque specification. Do not over-tighten.
- Replacement: If the nut shows signs of significant wear, thread damage, or corrosion that compromises its structural integrity, replace it immediately with a new, equivalent fastener. Do not reuse damaged fasteners in critical applications.
6. Troubleshooting
While flanged nuts are generally reliable, issues can arise. Here are common problems and their potential solutions:
- Nut Loosens Over Time:
- Possible Causes: Insufficient initial torque, vibration, thermal expansion/contraction, or improper thread engagement.
- Solution: Re-tighten to the correct torque specification. For high-vibration environments, consider using thread-locking compounds or additional locking mechanisms (if compatible and necessary for the application).
- Difficulty Threading the Nut:
- Possible Causes: Cross-threading, damaged threads on the nut or bolt, or debris in the threads.
- Solution: Ensure correct alignment before starting. Clean threads thoroughly on both the nut and bolt. Inspect both components for damage; replace if necessary. Never force the nut onto the bolt, as this will cause permanent damage.
- Nut or Fastened Material Damage:
- Possible Causes: Over-tightening, incorrect nut size or material for the application, or material fatigue.
- Solution: Always adhere strictly to specified torque values. Ensure the nut's material and size are appropriate for the intended load and mating components. Replace any damaged components immediately.
