Self-Tube

A two-piece fastening system comprising a blind rivet together with a semi-tubular rivet.  Use a standard 4mm steel blind rivet, and set it inside the semi-tubular rivet for a perfect joint.

• Rivet does not deform during setting, and is ideal for plastics, wood, and as a hinge in moving parts.
• Allows use in extra-wide material thickness (grips).
• Tamper-proof, smooth heads on both sides with excellent visual properties.
• High mechanical strengths.
