Nas1057 Spacers Repack (2025)
A NAS1057 spacer, often categorized as a "sleeve spacer," is specifically engineered for high-temperature and non-magnetic environments. Unlike standard commercial spacers, NAS-grade hardware provides:
refers to a specific series of aviation-standard spacers governed by the National Aerospace Standard (NAS) . These components are precision-engineered mechanical parts used to create specific distances or gaps between two components, typically between a structural surface and a fastener (such as a bolt or screw) head.
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.

Unlike standard washers, which are primarily used to distribute load, NAS1057 spacers are cylindrical sleeves with a precise length designed to position components accurately or provide clearance in structural assemblies.

Excited by his discovery, Jack ordered the spacers online from a specialty supplier who still carried the remnants of the old catalog's stock. Weeks later, a small package arrived at his doorstep, containing twenty NAS1057 spacers of various thicknesses, each meticulously wrapped and labeled. A NAS1057 spacer, often categorized as a "sleeve
Years later, as Jack looked over his well-organized garage, now filled with an array of projects and parts, his eyes would occasionally drift to the packet of NAS1057 spacers, now almost empty but still proudly displayed on a pegboard. They symbolized the beginning of a journey that had taken him from a hobbyist to a craftsman, one precisely machined spacer at a time.
| If you need… | Use this | |--------------|-----------| | General airframe spacing, low load | NAS43 series (hex) | | Precision bearing or alignment sleeve | NAS1066 or NAS1067 | | Wear-resistant, high-cycle | CRES NAS1066 with dry film lubricant | | A quick temporary spacer | MS21248 (but verify ID tolerance) |

Standardized dimensions and tolerances allow for consistent use across different manufacturers and aerospace platforms.
In structural joints, spacers are often used in shear applications. They ensure that the bolt shank is properly aligned and that the clamping force is applied to the structural members rather than the spacer itself failing under compression.
