STRUX® Clinch Studs and Nuts Optimal Performance in Thin Sheet and Aluminum Sheet Applications Acument® Global Technologies has developed a line of products to meet the increasing demand for fastener attachment in a wide range of steel and aluminum sheet applications. Our STRUX® line of clinch fasteners provides an external or internal thread in sheet metal stack-ups where welding is impossible or undesirable. ® STRUX Clinch Studs – External Threads Cost-effective, high performance alternative to other staked or welded products. STRUX® Clinch Nuts – Internal Threads A unique configuration offers unmatched performance and reliability when compared to competitive clinch products. One Of A Kind Performance Features º Heat treated to SAE grades, ISO classes or to your own specifications Studs: ISO 898-1 (metric), SAE J1199 (metric); SAE J429 (inch) Nuts: ISO 898-2 (metric); SAE J995 (inch) º Greater strength º May replace larger diameter, conventional weld or other non-heat treated studs º Displacement lobes and Retaining Groove º Resist push-out and rotation during service º Can be used where welding is impossible or undesirable, such as joining dissimilar materials, pre-coated sheets and high strength sheet materials º Unlike spot welding, joints can be created in-die with clinch fasteners and automated installation equipment º Lowers in-place costs º Maximizes assembly flexibility º Can be installed after the painting or coating process without aesthetic damage º Changes and damage to the application materials are minimized º Unlike welding, clinch fasteners do not create a heat zone in the materials during installation º No distortion due to excessive heat º Increased production rates when used in a progressive die º Improved product and joint integrity º Allows simple visual inspection º Joints do not require destructive testing to determine installed strength Eliminates hazardous welding operations Reduced potential for corrosion Provides a cleaner appearance than welded fasteners Improved centerline-to-centerline tolerances compared to weld studs and nuts Efficient Installation Options Installation of STRUX® fasteners can be achieved by using mechanical or hydraulic presses, whether your application calls for manual installation or fully automated in-line/in-die systems. Most equipment capable of feeding rivets, weld ® fasteners or conventional clinch fasteners will install STRUX fasteners.
