New Surplus, Sold Per Each

A self-locking hex nut is a type of hexagonal nut that is designed to resist loosening due to vibration or movement. It typically features an integrated locking mechanism that prevents it from turning or coming undone once it has been tightened. This locking mechanism can take several forms, such as a nylon insert or a deformed metal design, that either increases friction or mechanically engages with the threads of the bolt or stud, ensuring a secure fit.

NAS standards are maintained by the Aerospace Industries Association (AIA) and specify high-performance parts, such as fasteners and fittings, used in both military and commercial aerospace applications.

New Surplus: These parts are classified as new and unused, meaning they have not been installed or placed into service. However, they come without traceability or original manufacturer certifications, which might be required for certain high-level regulatory uses. Our company provides its own Certificate of Conformance (CoC) as a statement of assurance that the parts are in good working condition and have been sourced from reliable channels. These are ideal when the focus is on cost-effectiveness without compromising on quality.

Sold Per Each: This item is sold individually, with the price listed for a single unit. Perfect for purchasing the exact quantity needed without the requirement to buy in bulk. For larger quantities, consider reviewing any available bulk pricing options.

Product Testing: Every product is inspected for accuracy, quality, and functionality before shipping to meet our high standards.

Alternate Part Numbers: Due to the nature of ever-evolving part numbering structure, multiple part numbers may meet the same specifications and performance standards. If only an alternate part number is available, we will contact you to confirm compatibility. We strongly recommend consulting the appropriate repair manuals to ensure accuracy before using an alternate part.

Product Inspection: We inspect all products for functionality and condition before shipping to ensure you receive high-quality items. While our new surplus items may occasionally feature alternate part numbers, we ensure that these alternates meet the same specifications and performance standards as the original part. If only an alternate part number is available, we will contact you prior to shipping to confirm it meets your requirements.

Product Images: The product images provided are for reference and accurately represent the item you will receive. However, due to variations in manufacturer branding, packaging, or production updates, minor differences may occur. Any additional components, such as foam inserts or accessories, will be explicitly listed in the product description. If no foam inserts are shown in the images or mentioned in the description, the product will not include foam.

Damaged Orders: If your order is damaged upon arrival, please email Sales@AVBOXUS.com or call us at 850-466-3191 to report the issue.
