This M4 thread variant of Sealey's splined rivet nut threaded inserts is perfect for smaller, more delicate fixings where space is limited. The M4 size is commonly used in electronics enclosures, small brackets, and lightweight assemblies where a fine thread provides adequate strength without requiring excessive material thickness. Manufactured from zinc plated steel, these threaded inserts feature a splined body that grips firmly into the parent material during installation, preventing rotation under load. The one-sided installation method makes them particularly valuable when working with hollow sections or enclosed assemblies. Each pack contains 50 inserts, providing ample supply for multiple projects.
