✔️ M3 M6 M8 M10 M12 Steel Threaded Inserts Single Pack 50pcs

This pack contains fifty heavy duty rivet nuts designed for single side fastening. They anchor securely in metal wood and plastic sheets where welding or bolting from behind is impossible.

✅ Made from zinc plated carbon steel for strength and rust resistance ✅ Internally threaded tubular design fits screw heads flush and tight ✅ Install from one side with open end flange expansion mechanism ✅ Available in common metric sizes ranging from M3 up to M12

💡 Why choose sealed rivet nuts over normal bolts for thick panels?
Normally you need access to two sides of a metal sheet to secure a fastener tightly.

• Expand inward to grip panel edges securely without loose backing material
• Create durable thread channels easily in aluminum steel and composites
• Save time on assembly lines by replacing welding or drilling methods completely
