Screws and bolts are commonly used as structural and non-structural fastening materials in aerospace, military and a wide range of industrial applications. Although quite often these terms are used interchangeably, screws differ from bolts as they are generally made of lower strength materials.Screws can be installed with a loose fitting thread, and the head shapes are made to engage a screwdriver or wrench. Some screws have a clearly defined grip (unthreaded portion) while others are threaded along their entire length (fully threaded). Bolts are generally used in high strength demanding applications. Where this strength is not required, the use of screws remains an option.

Like other fasteners, screws and bolts comform to different specifications/standards (aerospace/military or industrial) and are structured in families (series) based on their conforming standard. U.S. military standards such as those of Army & Navy (AN), superseded by Military Specs (MS) which in turn have been converted to National Aerospace Standards (NAS) by tthe U.S. Aerospace Industries Association (AIA) is an example of Standards used for aerospace screws and bolts. Other international & national Standards, such as ISO, European Standards (EN), the American National Standards Institute, the American Society for Testing and Materials (ASTM), German DIN, British BSI, or those adopted by major airframe builders (such as Boeing (BAC) or Airbus (ASNA) are also used as part of standardisation efforts of these fasteners from governments and the industry worldwide.

An extensive collection of screws, bolts, and other fasteners complying with the above standards is already listed in our Web Platform for Supplies. Sourced from quality manufacturers, these fasteners are offered in different materials, finishes, and sizes in Imperial (inch) or Metric (mm) measurement systems. They can be furnished either as OEM parts of their respective manufacturers or as parts of our own labelled (AVIATIONEU NEW ERA) product lines. Usually sold in pieces but also in packs for convenience and economy, where the number of fasteners per pack is indicated after the letters "PK" in the product SKU. Appearing prices are always for the used unit of measurement each time. As these fasteners come in countless combinations of conforming standards, types, materials, finishes, and inch or metric sizes, some parts may be missing. In this case please contact us as these may be also available through our network of co-operating suppliers.
