Assembly Tools & Systems

Emhart Teknologies offers a variety of assembly tools and systems including stud welding systems, designed to fasten without holes, and Self-Piercing Riveting (SPR)  systems, used to join layers of material without predrilled or punched holes. 

Handheld & Multiple-Spindle Torque Tools

These powerful systems from Stanley Assembly Technologies incorporate the latest pneumatic and DC electric nutrunner innovations for both handheld and multi-spindle applications.  Multi-spindle nutrunners and unique bolt-holding tools incorporate synchronization, absorption of reaction torque, full-featured operator feedback, and error-proofing options. Handheld tooling offers superior quality, ergonomics, durability, and productivity with simple-to-interface error-proofing and network capabilities.  

Stud Welding Systems

Emhart Teknologies pioneered the concept of using arc welding equipment as a means to fasten components without the need for holes in sheet metal. Available from SPR and Tucker, this system is known as the No-Hole Fastening System, which allows extraordinarily strong attachments that will never be a source of corrosion or fastening system failure. Modular, microprocessor-controlled stud welding systems allow customized equipment precisely matched to specific customer requirements. 

Self-Piercing Riveting (SPR) 

Self-Piercing Riveting (SPR) is a process used to join two or more layers of material without a predrilled or punched hole by driving a rivet through the top layers of material and upsetting the rivet in the lower layer without piercing the layer to form a durable joint. SPR is an ideal process for joining sheet materials providing a watertight joint. This system provides process-monitoring capabilities to enable increased productivity and quality.
