For medium rivets of different alloys, what type of gun delivers approximately 2500 blows per minute?

• A. Fast hitting
• B. Impact wrench
• C. Medium hitting
• D. Slow hitting

Answer: (C)

The type of gun that delivers approximately 2500 blows per minute is categorized as a medium hitting gun. These guns are specifically designed to provide sufficient force and speed to effectively drive medium rivets used in various aviation applications. The term "medium hitting" refers to the balanced performance where the blows per minute are sufficient to achieve the desired result without causing excessive damage or distortion to the workpieces.

Medium hitting guns are essential in applications where consistency and precision are crucial. They allow for the proper setting of rivets in materials without compromising their integrity. This makes them ideal for working with different alloys of medium rivets, ensuring that the fasteners are securely and accurately installed.

In contrast, fast hitting guns would exceed this blows per minute rate, which could lead to potential issues with rivet and material damage. Slow hitting guns deliver fewer blows and are less suitable for the fast pace required in tasks involving medium rivets. An impact wrench serves a different purpose, primarily designed for loosening or tightening bolts and nuts rather than for installing rivets. Therefore, the medium hitting gun is the appropriate choice for the specified task.
