POP Advel Countersunk Rivet Head for NeoSpeed Speed Fastening system

POP Avdel, a division of STANLEY Engineered Fastening, is now offering a countersunk rivet head option to go with the more common mushroom style for use with its NeoSpeed Speed Fastening system. 

• Countersunk rivets are particularly important for applications in which a raised head is not acceptable
• Unique, splined design 
• Delivers wide grip range and hole size tolerances
• Provides shear, tensile and clamp performance better than or equal to traditional breakstem options 
• Assembly speeds can be improved by up to 400% when used with appropriate installation tools, including a paper magazine of fasteners with a re-usable mandrel or pre-loaded rivets with disposable mandrel compared to traditional threaded or breakstem fasteners
• NeoSpeed repetition riveting system uses pull-through technology with a re-usable mandrel or a pre-loaded disposable mandrel (except for countersunk and A4 Stainless Steel) for installation
• Eight axial splines of trapezoidal cross-section are precisely defined in form to permit variable “radial crushing” within the hole according to its size, and can expand radially 5.9 mm (0.23 in.) unconstrained
• During placing operation, splines at tail end expand first and capture rear sheet and hole-filling then occurs within the joint
• For final clamp load, the mandrel head completes the “head forming” action as it pulls through, and as a result the rivet can fill out into bigger front sheet holes than rear, accommodate for misaligned holes, and potentially eliminate rattles and shear-slip 
• Eliminating waste portion of the stem ensures there are zero waste materials to dispose
• Installed rivets are typically half the weight – a critical consideration in many applications, including air and ground vehicles seeking to improve fuel efficiency
• Enhances product quality and joint performance by having fewer failure modes than breakstem riveting
• Reliable rivet process minimizes the chance of jaw clogging, stem jams, metallic debris, as well as spent pintails dropped in the application
• Features three times greater hole size tolerance than standard breakstem rivets and an enlarged front sheet hole that minimizes misalignment issues
• Multi-grip capability further accommodates wide variations in material thickness so one rivet can be used to replace several standard grip fasteners
• Available in three rivet lengths per diameter
• Only one mandrel is required per diameter, regardless of hole size variation
• Custom rivet lengths can be developed to accommodate specific grip range application
• Available in aluminum, steel and A4 Stainless Steel (316) with various finishes
• Sizes include 3.2 mm (1/8 in.), 4.0 mm (5/32 in.) and 4.8 mm (3/16 in.)
• “Short-grip” version is available that is lighter and costs less for common thin sheet metal joints where individual sheet thickness is typically below 1.2 mm (0.05 in.)
