Multi Lock / Monobolt is a structural blind rivet designed for fast, reliable fastening when only one side of the assembly is accessible. This versatile fastener fills the hole during installation and delivers a secure, vibration-resistant joint with a tight, moisture-resistant seal.
A built-in circle-lock design creates a mechanical lock between the pin and sleeve during installation. That lock makes inspection simple, since a quick visual check confirms proper installation and a consistent, flush pin break. Compared to many structural blind rivets, Multi Lock / Monobolt does not require a special nose-piece insert for proper installation, helping crews keep production moving with fewer tooling changeovers.
Available in steel, stainless steel, and aluminum, Multi Lock / Monobolt is offered in diameters up to 1/2" and supports wide grip ranges for flexible use across varying material thicknesses. Strong gap-pull performance and high retained clamp make it a dependable choice for structural assemblies exposed to vibration, moisture, and demanding service conditions.
