The Hemlok® rivet features an interference lock ensuring the strongest vibration-resistant joints.
This structural breakstem fastener has exceptional shear and tensile strength and a large blind side bearing area against the rear sheet. The large blind side bearing area spreads the load and prevents creep.
The Avdel® Hemlok® fastener can be used to fasten metal to metal, metal to plastic, and thin sheet to thick metal.
Assembly applications include automotive, warehouse racking, and ladders.
