Designed for use in composite laminates but equally well suited to metal structure, the Composi-Lok family of fasteners provides superior joint integrity. Composite laminates are capable of sustaining high loads but are subject to delamination when fastened with conventional fasteners. By providing a large blind side upset, hailed by some as the industry benchmark, Composi-Loks distribute bearing loads over a large area overcoming damage to the composite. The characteristic large blind side bearing area or footprint allows the fastener to impart very high clamp loads to the structure without damage to the composite. Structural integrity in severe vibration environments is assured by a patented locking feature. Proper installation can be achieved with simple and compact hand or power tools and verified from one side of the structure by measurement of the screw break-off position. Available in four distinct 75 KSI shear strength versions, all Composi-Loks are completely compatible with graphite and are not subject to galvanic corrosion. Composi-Loks are available in 5/32 through 3/8 diameters, including oversizes, and have a .050 operational grip range.
Composi-Lok IIfasteners incorporate Monograms drive nut concept further simplifying the installation process by incorporating a disposable hex drive nut. The hex drive nut provides a positive fastener-to-tool engagement and eliminates the tendency for flush style fastener recesses to cam-out during installation. Since the drive nut is common to a variety of diameters and all head styles only three nose pieces are required to install the entire Composi-Lok line. Nose pieces never wear out and the disposable magnetic drive nut stays on the discarded pintail after installation permitting easier retrieval and minimizing the chances of small pintails finding their way into F.O.D. critical areas. Composi-Lok IIa and Composi-Lok3 variations also incorporate the drive nut feature.
