Structural Rivets

H-Lock High Strength Structural Rivet

H-Lock high-strength structural rivets utilize a grooved mandrel design that mechanically locks within the rivet body during expansion. This permanent locking prevents mandrel loss and rattling while imparting high shear and tensile resistance under severe shock and vibration conditions. The fastener expands precisely against the closing head, producing a powerful grip and a splash-proof joint without requiring two-sided access. Typical applications involve locomotive construction, heavy equipment enclosures, and high-stress sheet metal fabrication.
