CHERRY® AEROSPACE CherryLOCK® Bulbed Rivet, 1/8 in, 2.15 in L, 1/4 in, 0.054 in

Bulbed CherryLOCK® rivets are locked spindle and flush fracturing structural rivets. They conform to procurement specification NAS1740 and standards pages NAS1738 and NAS1739. Bulbed CherryLOCK® is a complete shear fastening system. Its features can be utilized for optimum strength and performance in both thick and thin sheets. It provides the highest possible design integrity, particularly in double dimple or thin backside sheet applications. CherryLOCK® hydroshift installation tool systems are required for installation.

Features
• Similar to a solid rivet ensures higher tensile, shear and fatigue strengths
• Assured structural reliability in blind and non-blind applications
• Increased fatigue strength
• Higher shear strength, lower flush head height for use in thin sheets
• No shaving, even in thin sheet applications
• Grip, materials and manufacturer's identification for installed inspection
• High stem break load provides high preload, higher fatigue strength

Technical Information
• Meets NAS1740, NAS1738
