Review PIPER Aircraft Bolt P/n New Surplus fits ST

The Piper PA-400-547 aircraft bolt is a crucial component in ensuring the structural integrity of this renowned aircraft model. This bolt, specifically identified by its part number 547, is a standard fastener used extensively throughout the Piper PA-400 series.

Measuring approximately 1.5 inches in length, this bolt is manufactured from high-strength alloy steel, ensuring it can withstand the rigors of frequent flight. Its hexagonal head, featuring a 3/8 inch drive, allows for easy installation and removal using standard socket wrenches. The hex head is also countersunk on one side to enable a flush installation for an aesthetically pleasing appearance.

The bolt s thread conforms to the SAE J429 Grade 5 specification, boasting a minimum tensile strength of 120,000 psi. This ensures a secure connection between the bolt and the mating components. Additionally, the threads are rolled to provide superior thread engagement and resistance to loosening.

The bolt's body undergoes a thorough electroplating process, which provides an additional layer of protection against corrosion. This coating not only helps extend the life of the bolt but also ensures the aircraft remains safe and airworthy for longer periods.

In summary, this Piper PA-400-547 aircraft bolt is an essential piece of hardware, designed to meet the demanding requirements of the PA-400 series aircraft. Its high-strength alloy steel construction, thread specifications, and corrosion-resistant coating make it a reliable and long-lasting solution for maintaining your aircraft's structural integrity.

Buying a new bolt for a Piper PA-400-547 aircraft (hereafter referred to as the Piper Seneca) can be a crucial decision for aircraft owners and maintenance providers. Although seemingly insignificant, a faulty or worn-out bolt can lead to serious safety concerns and potential costly repairs. Let's explore some pros and cons of purchasing a new bolt for your Piper Seneca.

1. Safety: A new bolt ensures that your aircraft is in optimal condition, reducing the risk of in-flight failures or accidents.

2. Reliability: New bolts come with a warranty and are manufactured to meet high-quality standards, ensuring long-lasting performance.

3. Compliance: Adhering to regular maintenance schedules, including replacing worn-out bolts, is essential for maintaining FAA compliance.

4. Peace of mind: Knowing that your aircraft is equipped with new and reliable components can provide valuable peace of mind.

1. Cost: New bolts can be more expensive than used or reconditioned ones. However, considering the potential safety risks and long-term savings, the investment may be worthwhile.

2. Availability: Depending on the specific bolt model and the availability from the manufacturer or authorized dealers, there might be a wait time for delivery.

3. Installation: Installing a new bolt requires a certain level of expertise and time, which could incur additional labor costs.

In conclusion, while the upfront cost of purchasing a new bolt for your Piper Seneca might be a concern, the long-term safety, reliability, and compliance benefits make it a worthwhile investment. Considering the potential risks associated with a failing bolt, it's essential to prioritize the use of new, high-quality components.

When it comes to purchasing a new bolt for your Piper Seneca, we recommend researching and contacting trusted aviation parts suppliers or the manufacturer directly for the best pricing and availability.
