Nas1056 Spacers Portable Jun 2026

Specifically categorized as "Sleeve-Rivet" spacers.

Spacers are frequently passivated to further protect against environmental wear. nas1056 spacers

Because they meet stringent military and aerospace criteria, NAS1056 spacers are found in environments where failure is not an option: Specifically categorized as "Sleeve-Rivet" spacers

| Material | Tensile Strength (min) | Hardness | Use Case | |----------|------------------------|----------|-----------| | Steel (cad plated) | 125 ksi | Rockwell C 22–30 | High load, shear applications | | CRES 303 | 85 ksi | B85 | General corrosion-resistant | | CRES 17-4PH (H900) | 180 ksi | C40 | Extreme strength | | Aluminum 2024-T4 | 65 ksi | B70 | Weight-critical assemblies | Dimensional Variety

| Property | Detail | |----------|--------| | Standard | NAS1056 (NAS = National Aerospace Standard) | | Type | Unthreaded spacer / standoff | | Material options | Steel (cad), CRES (pass), Aluminum (anodize) | | Length range | 0.125″ – 2.000″ (1/16″ increments) | | ID range | ~0.147″ (#6) to 0.502″ (1/2″) | | Key tolerance | Length ±0.005″, ID/OD ±0.002″ | | Primary use | Precision spacing with NAS bolts in aircraft |

The NAS1056 standard governs specific dimensions:

They are typically passivated (per AMS2700 or ASTM-A967-05) to further enhance surface protection and remove free iron. Dimensional Variety
