The Aircraft Spruce Specialty AN3-21A Undrilled Bolt is heat treated to ensure its strength and durability. It has a minimum tensile strength of 110,000 psi and a yield strength of 95,000 psi. The bolt also has a Rockwell hardness of C30H, which provides good resistance to fatigue and stress.

The AN3-21A Undrilled Bolt is packaged individually in protective plastic bags to prevent damage during transportation and storage. Each bolt is inspected and tested to ensure it meets the highest quality standards. The bolt comes with a certificate of conformity that verifies its compliance with the relevant aviation specifications.

In summary, the Aircraft Spruce Specialty AN3-21A Undrilled Bolt is a high-quality, corrosion-resistant fastener designed for use in aerospace applications. It is manufactured from SAE 303 Stainless Steel and has a hex head, solid shank design with a thread length of 0.437 inches and a diameter of 0.120 inches. It is suitable for use with AN3-21A nuts and is inspected and tested to meet the highest quality standards.

Aircraft Spruce Specialty AN3-21A undrilled bolts are commonly used in aviation industry for various applications due to their high tensile strength and durability. Here are some pros and cons of buying these bolts:

1. High Tensile Strength: AN3-21A bolts have a minimum tensile strength of 110,000 psi, making them suitable for use in high-stress applications in aircraft structures.

2. Corrosion Resistance: These bolts are made of SAE 304 stainless steel, which provides excellent corrosion resistance, ensuring longevity in harsh environments.

3. Precision Manufacturing: Aircraft Spruce Specialty bolts are manufactured to strict tolerances, ensuring consistent quality and fit.

4. Widely Used: These bolts are widely used in the aviation industry for various applications, including engine mounts, wing attachments, and landing gear.

1. Cost: AN3-21A bolts are more expensive than standard bolts due to their high-performance materials and manufacturing processes.

2. Availability: These bolts may not be readily available at local hardware stores or suppliers, and may need to be ordered from specialized aviation parts suppliers.

3. Handling and Installation: Due to their high tensile strength, these bolts require special tools and techniques for handling and installation to prevent damage and ensure proper torque.

Aircraft Spruce Specialty AN3-21A undrilled bolts offer superior performance and durability, making them an essential component in the aviation industry. However, their high cost and limited availability may make them a less practical choice for some applications outside of aviation. If you require high-strength, corrosion-resistant bolts for a critical application, these bolts may be worth the investment.

If you need AN3-21A bolts for an aviation application, it is recommended to purchase them from a reputable aviation parts supplier to ensure authenticity and quality. Make sure to have the proper tools and techniques for handling and installation to ensure proper torque and prevent damage. If you are unsure whether these bolts are necessary for your application, consult with a qualified aviation engineer or technician for guidance.
