Set screws (ISO 4026)

ISO 4026 set screws: 71 sizes. Dimensions: length, shank diameter. Threads M3, M4, M5 and more. Use parts in kernelCAD Studio or MCP.

Use a size in a model

Every size is a catalog part with a STEP solid and mate connectors. Use a code-CAD script, or ask an agent through the MCP fetch_part tool, by its part ID:

const part = await lib.fetchPart('iso-4026-m3x4');
