Frequently Asked Questions
Q: What aluminum profile sizes are these spring nuts compatible with?
A: These carbon steel spring nuts are designed for European Standard Aluminum Profiles in 30, 40, 45, and 50 series slots. The full size range includes 30/40-M4, 30/40-M5, 30/40-M6, 30/40-M8, 40-M6, 40-M8, 45/50-M6, and 45/50-M8 — making them highly versatile for most common aluminum extrusion frameworks.
Q: How do these elastic/spring nuts work?
A: The spring-loaded mechanism allows you to simply slide the nut into the T-slot channel of your aluminum profile at any point along its length. The built-in shrapnel (spring plate) holds the nut in position automatically, so it won't fall out while you align and tighten your bolt — no hammering or pre-threading needed.
Q: Are these nuts suitable for heavy-duty industrial use?
A: Yes. Made from carbon steel, these T-slot spring nuts offer excellent structural integrity and are well-suited for industrial frames, CNC machine enclosures, 3D printer builds, workbenches, and other demanding metalworking or fabrication applications.
