Nas1829 Male-female Standoffs !free! -

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 | nas1829 male-female standoffs

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? Note: Metric equivalents exist under different standards (e

In this post, we’ll break down what the NAS1829 specification means, where to use these standoffs, and how they differ from commercial hardware. The NAS prefix stands for National Aerospace Standard . NAS1829 is a specific dimensional and performance standard for self-locking, key-locked, male-female standoffs . In this post, we’ll break down what the

Here is the reality check:

| 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. |
