Nas1829 Male-female Standoffs May 2026

If you are designing or assembling avionics, military electronics, or any high-vibration system, you’ve likely run into a common problem: How do you stack circuit boards securely without shorting them out or loosening under G-force?

Here is the reality check:

The answer for aerospace-grade applications is often the .

| Feature | Commercial Standoff | NAS1829 Standoff | | :--- | :--- | :--- | | | Requires threadlocker or lock washer. | Built-in prevailing torque (self-locking). | | Stacking accuracy | Variable height tolerance (±0.010" typical). | Tight military tolerance (±0.005" or better). | | Material | Brass, nylon, or low-grade steel. | Corrosion-resistant steel (CRES) or stainless steel passivated. | | Certification | No traceability. | Full material lot traceability & certification. |

Note: Metric equivalents exist under different standards (e.g., NAS1829M), but the original NAS1829 is inch-based. Because NAS1829 is a certified aerospace part, you cannot buy them at a local hardware store or even from general electronics suppliers like Digi-Key (unless specially stocked).

| Thread Size | Typical Hex Width | Standard Lengths (inches) | | :--- | :--- | :--- | | #2-56 | 1/8" | 0.250, 0.375, 0.500 | | (Most common) | 3/16" | 0.250 through 1.000 | | #6-32 | 1/4" | 0.500 through 1.500 | | #8-32 | 5/16" | 0.500 through 2.000 |
