An asphalt nailing gun, often referred to as a roofing nailer, is a specialized tool used in roofing applications. These guns are designed to rapidly drive nails into asphalt shingles and other roofing materials. Central to the operation of an asphalt nailing gun are the 22 shells, which are essentially the ammunition for these tools. In this article, we will provide a concise technical overview of asphalt nailing guns and the 22 shells they use.

The Asphalt Nailing Gun

Design and Operation:
Asphalt nailing guns are typically pneumatic or electric tools designed for roofing tasks. Here are the key technical aspects:

• Power Source: Pneumatic models are powered by compressed air, while electric ones use electricity. Pneumatic models offer high power-to-weight ratios, making them suitable for professional roofers.

• Nail Size Compatibility: These guns are engineered to accommodate specific nail sizes, often ranging from 3/4 inch to 1-3/4 inch. The depth and angle of nail penetration can often be adjusted to suit the roofing material.

• Magazine Capacity: The magazine on an asphalt nailing gun holds a specific number of nails. It can vary from 120 to 300 nails, depending on the model.

• Safety Mechanisms: These tools typically feature safety mechanisms to prevent accidental discharges and protect the user.

Uses:
Asphalt nailing guns are primarily used for roofing projects, and sometimes for siding and sheathing applications. They offer speed and efficiency, making them invaluable for large-scale roofing jobs.

Considerations:

• Users should ensure the nails and 22 shells are compatible with their specific nailing gun model.
• Regular maintenance is essential to keep the tool in good working condition.

The 22 Shells

Overview:
The 22 shells, also known as 22-degree plastic collated nails or simply "22s," are the nails designed to be used with asphalt nailing guns. Here are the essential technical details:

• Collation Type: 22 shells are collated in a plastic strip, which simplifies loading and reduces the risk of jamming.

• Nail Composition: These nails are typically made from galvanized steel or other materials that resist corrosion to ensure the longevity of the roof.

• Nail Angle: The 22-degree angle of these nails is a standard for most roofing nailers, ensuring compatibility across various models.

• Nail Length and Diameter: The specific nail length and diameter can vary based on the roofing material and the manufacturer’s recommendations.

Advantages:

• The plastic collation of 22 shells is durable and minimizes the risk of jamming during operation.
• These nails are designed to resist corrosion, ensuring the integrity of the roofing structure.

Considerations:

• Proper nail selection is crucial to ensure the roof’s structural integrity and longevity.
• It’s essential to follow manufacturer guidelines for nail size and material compatibility with the roofing material.

In conclusion, asphalt nailing guns and their 22 shells are fundamental tools for roofing professionals and enthusiasts. These tools offer efficiency and precision, crucial for roofing projects where speed and accuracy are paramount. By understanding the technical details and ensuring proper nail selection, users can achieve durable and reliable roofing installations. Regular maintenance and adherence to safety guidelines are key to the long-term success of these tools.
