A21 A20 A19 A18 A17 A16 A15 A14 A13 A12 A11 A10 MONOBOLT® BLIND FASTENING SYSTEM The Monobolt® rivet is a hole filling, multi-grip, structural breakstem rivet available in steel or aluminum construction. Multi-grip means the rivet has the capability to join component parts having a broad range of thicknesses, thus reducing inventory where a variety of rivet sizes might otherwise be necessary. Hole filling means the rivet will expand radially into the application hole to provide a strong, vibration resistant joint and compensate for irregular, oversized, slotted or misaligned holes. Also, it can stop sheet movement in applications with non-standard holes. However, the main feature of the Monobolt® rivet is an internal, mechanical lock of the rivet stem. A special nose tip with a cutting ring (anvil) is required. During installation, when the mandrel head comes in contact with the nose tip, the anvil cuts into and folds material from the mandrel head (skive) into a ledge located in the inner diameter of the rivet head. This prevents the mandrel from falling back through the rivet. Additionally, the locked stem forms a weather tight seal and provides a very strong, vibration resistant joint without the damage, electrical problems or rattling due to loose stems. • Multi-grip capability. • High shear and tensile strength. • Good sheet take-up performance. • Visible lock for quick and easy inspection. • Excellent hole fill via rapidly expanded body. • Stem mechanically locked into body. • One fastener can be used to replace several standard grip fasteners. • Reduced fastener inventory and simpler stock control. • Compensates for irregular, oversized, slotted or misaligned holes. • Can stop sheet movement in non-standard holes. • Large gap closing capability. • No damage, electrical problems or rattling due to loose stems. NOTE: We recommend using the Huck Magna-Lok fastening system on the previous page. It provides superior performance at a lower price. Huck Magna-Lok fasteners do not require the use of a nose piece like monobolts do. See page A19-26 for nosepieces.
