Blind Bolts

The industry leading Visu-Lok family of fasteners, designed for use in metal structure, have addressed the need for cost effective one-sided fastener installation for decades.

Designed for use in composite laminates but equally well suited to metal structure, the Composi-Lok family of fasteners provides superior joint integrity.

Offering 360° radial expansion throughout the fastener grip, Monogram’s unique Radial-Lok® blind bolt’s design properties are unmatched by any other blind bolt.

The revolutionary OSI-Bolt® is a direct replacement for solid shank pin and collar systems.
