Product Description

Visu-Lok Fasteners The Visu-Lok family of fasteners, designed for use in metal structure, have addressed the need for cost effective one-sided fastener installation for decades. The basic design of the Visu-Lok is based on one of the oldest and time proven principles; the nut and bolt. However the Visu-Lok, unlike conventional nut and bolt pairings, is fully installed and verified from one side of the structure. With the ease of its one man, one-sided installation process the self-locking Visu-Lok forms a solid blind side head delivering high tensile, shear and fatigue values and guaranteed 20% minimum preloads. This simple installation process can be accomplished with either hand or compact power tools operating at standard air pressure levels and can be further simplified by adopting Monogram drive nut concept.
