Jack had been struggling to finish a custom shelving unit. The design required a series of precisely aligned shelves, and Jack was having trouble achieving the level of accuracy he wanted with the materials on hand. The NAS1057 spacers, with their accurately machined surfaces and corrosion-resistant coating, seemed like the perfect solution.
| NAS1057 Material (typical) | Spacer Material Recommendation | |----------------------------|--------------------------------| | Cadmium-plated alloy steel | CRES 303/304, or cad-plated steel | | Corrosion-resistant steel (CRES) | CRES (passivated) | | 2024-T4 aluminum (rare for NAS1057) | Al 2024 anodized or CRES (with isolation) | nas1057 spacers
| Feature | NAS1057 Spacer | Standard Washer (NAS1149) | | :--- | :--- | :--- | | | To create a specific gap/length. | To distribute bearing load. | | Length | Significant length relative to diameter. | Very thin (minimal thickness). | | Tolerance | Length tolerance is tightly controlled. | Thickness tolerance is less critical. | | Load Application | Designed for compression/standoff. | Designed to prevent pull-through. | Jack had been struggling to finish a custom shelving unit
