A Rivet Set Used to Drive MS20470 Rivets Should… Be the Right One! A Comprehensive Guide

Choosing the right rivet set is crucial for successfully installing MS20470 rivets. Using the incorrect tool can lead to damaged rivets, compromised structural integrity, and potentially dangerous consequences. This comprehensive guide dives deep into the specifics of MS20470 rivets and the ideal rivet sets needed for their proper installation. We’ll cover everything from understanding rivet types to selecting and maintaining your tools, ensuring you achieve professional-quality results every time.

Understanding MS20470 Rivets: The Foundation of a Strong Joint

MS20470 rivets are a specific type of military specification (MS) solid shank rivets, known for their high strength and reliability. They are typically used in aerospace, defense, and other critical applications where structural integrity is paramount. Understanding their key characteristics is essential before discussing appropriate rivet sets.

Key Characteristics of MS20470 Rivets:

• Material: Generally made from high-strength aluminum alloys, offering a balance of weight and strength. Specific alloy composition will vary depending on the application's requirements.
• Shape and Size: Available in various diameters and lengths, carefully selected to match the material thickness being joined and the desired joint strength. The dimensions are precisely defined within the MS20470 specification.
• Head Style: Commonly feature a countersunk head, providing a flush or near-flush surface finish after installation. This is crucial for aerodynamic considerations in applications like aircraft manufacturing.
• Installation Method: Require a specialized rivet set and a powerful riveting machine or pneumatic hammer for proper installation. Manual installation is generally not recommended due to the risk of inconsistent setting.

Selecting the Right Rivet Set: Precision is Key

The rivet set is the critical tool that shapes the rivet head during installation. Using an incorrect set will result in improperly formed heads, weakening the joint and potentially leading to failure. Several factors influence the choice of rivet set:

1. Rivet Diameter: A Perfect Fit is Essential

The diameter of the rivet set's anvil must precisely match the diameter of the MS20470 rivet being installed. Using a set that's too small will lead to incomplete head formation, while a set that's too large can damage the rivet or the surrounding material. Always check the rivet's specifications to ensure compatibility.

2. Head Style: Achieving the Correct Profile

The shape of the rivet set's anvil must correspond to the head style of the MS20470 rivet. Countersunk rivets require a countersunk anvil, ensuring a smooth, flush head. Using the wrong anvil shape will result in an uneven, poorly formed head, compromising joint strength and aesthetics.

3. Material Compatibility: Preventing Damage

The material of the rivet set should be sufficiently hard to withstand the stresses of riveting, while also being resistant to deformation or damage. High-quality steel or hardened alloy steel rivet sets are generally preferred for MS20470 rivets. Avoid sets made from softer materials that could deform during use.

4. Handle Design: Comfort and Control

While less critical than the anvil, the handle design influences ease of use and control during installation. Ergonomically designed handles reduce hand fatigue and improve precision, especially during extended use. Consider the length and shape of the handle, opting for a design that feels comfortable and provides sufficient leverage.

Types of Rivet Sets for MS20470 Rivets: Understanding the Options

Various types of rivet sets cater to different needs and preferences:

1. Solid Rivet Sets: The Standard Choice

Solid rivet sets are the most common type, characterized by their solid, one-piece construction. They offer good durability and are suitable for most MS20470 rivet applications. However, they may require more force during installation.

2. Split Rivet Sets: Increased Flexibility

Split rivet sets offer greater flexibility and are sometimes preferred for working in tight spaces. Their split design allows for easier insertion and removal of the rivet.

3. Combination Rivet Sets: Versatility in One Tool

Combination sets incorporate multiple anvils with different diameters and head styles, offering versatility without having to change tools repeatedly. This is advantageous when working with different sizes of MS20470 rivets.

Maintaining Your Rivet Sets: Ensuring Long-Term Performance

Proper maintenance significantly extends the lifespan of your rivet sets and ensures their continued accuracy.

1. Regular Inspection: Identifying Wear and Tear

Regularly inspect your rivet sets for any signs of wear, such as chipping, cracking, or deformation of the anvil. Damaged sets should be replaced immediately to avoid compromising the quality of rivet installations.

2. Cleaning: Removing Debris and Residue

After each use, clean the rivet set's anvil and other parts to remove any metal shavings or debris. This prevents the buildup of material that could affect the accuracy of subsequent installations.

3. Storage: Protecting Against Corrosion

Store your rivet sets in a dry, clean place to prevent corrosion or damage. Consider using protective coatings or storage cases to maintain their condition.

Beyond the Rivet Set: Essential Tools and Techniques

While the rivet set is paramount, successful MS20470 rivet installation requires additional tools and techniques.

1. Bucking Bar: Providing Counter Pressure

A bucking bar is essential to provide counter pressure to the rivet during installation. This is crucial to prevent damage to the rivet or the work piece and to ensure a proper head formation. The bucking bar should be appropriately sized and made of a durable material.

2. Pneumatic or Hydraulic Riveting Gun: Power and Precision

A powerful riveting gun is necessary to drive MS20470 rivets securely. Pneumatic or hydraulic riveting guns offer controlled and consistent force, making them preferable over manual methods. The gun should be properly calibrated and maintained.

3. Safety Equipment: Protecting the User

Always wear appropriate safety gear when working with riveting tools, including safety glasses, gloves, and hearing protection. The high forces involved in rivet installation can pose risks to the eyes, hands, and ears.

Troubleshooting Common Problems: Identifying and Resolving Issues

Even with the right tools, problems can arise during MS20470 rivet installation.

1. Uneven Head Formation: Incorrect Anvil or Rivet Set

Uneven head formation often indicates an incorrect anvil or a damaged rivet set. Verify that the anvil perfectly matches the rivet's diameter and head style. Replace damaged sets immediately.

2. Rivet Breakage: Insufficient Force or Material Defects

Rivet breakage can occur due to insufficient force during installation or defects in the rivet material. Ensure the riveting gun is delivering adequate force and check the quality of your rivets.

3. Material Damage: Excessive Force or Improper Technique

Damage to the surrounding material points to excessive force or improper technique. Reduce the force applied, check your bucking bar placement, and ensure proper alignment.

Conclusion: Mastering MS20470 Rivet Installation

Successfully driving MS20470 rivets requires the right tools, techniques, and attention to detail. Choosing the appropriate rivet set, maintaining your tools, and employing safe practices are all crucial steps towards achieving high-quality, structurally sound joints. Remember, using the wrong rivet set can have serious consequences, so always prioritize precision and safety in your work. This comprehensive guide serves as a valuable resource in understanding the nuances of MS20470 rivet installation, enabling you to perform the task with confidence and expertise. By following these guidelines, you can ensure your projects meet the highest standards of quality and reliability.
