Nas43 Spacers «High-Quality»

A is a specific standard for a plain, circular spacer (sometimes referred to as a flat washer or collar). While it may look like a simple metal ring to the untrained eye, the NAS43 is engineered to exacting tolerances that generic commercial washers simply cannot match.

If you are sourcing or specifying a :

Based on the model number format (which typically refers to a series of military/aerospace standard spacers, bushings, or standoffs), a “solid post” would likely be a NAS43 series spacer with zero clearance / solid wall construction , as opposed to a “weld nut” or “floating” version. nas43 spacers

Because they are predominantly made from stainless steel (CRES), NAS43 spacers offer excellent resistance to rust and galvanic corrosion, which is vital for aircraft operating in humid or marine environments. A is a specific standard for a plain,

The NAS43 spacer was first introduced in the 1950s by the National Aerospace Standards Committee (NASC), a organization established to standardize aerospace components. The NAS43 spacer was designed to provide a simple and reliable means of maintaining structural integrity in aircraft and spacecraft. Initially, NAS43 spacers were made from a variety of materials, including aluminum, steel, and titanium. However, as aerospace engineering evolved, so did the materials and design specifications for NAS43 spacers. Because they are predominantly made from stainless steel
