iCRIMP / SN SERIES
Choose the jaw that fits your connection.
Ten hand crimpers for different terminal profiles. Compare the jaw, wire range and contact before choosing your model.
One selected tool with its fitted die. Terminals, connector assortments and spare dies are not included.
Find your SN model
Compare jaw profile, terminal example and wire range first. Each model uses a different die shape; matching AWG alone does not guarantee fit.

Select model aboveContact examples
Contact names are selection examples, not blanket compatibility claims. Match the exact terminal part number, conductor size, insulation diameter and required crimp profile. Die dimensions describe the tool geometry, not the finished crimp height.
A better crimp starts with the right match
Match the terminal and cavity. Strip to the terminal maker’s specified length, position the conductor and insulation tabs, complete the tool’s cycle, then inspect the connection against the terminal specification.
Why do models with the same AWG range differ?
Wire range is only one part of the fit. Conductor and insulation cavities differ in width, height and thickness. Open a model’s dimensions above to compare.
What is included?
One selected SN tool with its fitted die. This is not a ten-tool set.

Returns & warranty terms · Shipping detailsDesign standards & application compatibility
Check the exact model, connection type and applicable standard before ordering. A standard referenced in a product description is not, by itself, evidence of third-party certification. Ask us for model-specific documentation if your project requires it.
Design references are not third-party product certifications. Use the model specifications and the fitting or terminal manufacturer's instructions to confirm compatibility.
How manufacturing supports reliability
IWISS manufacturing capabilities include precision machining, heat treatment, assembly and quality inspection, with dimensional measurement and tensile-testing equipment. The inspection method and acceptance criteria depend on the tool and connection application.
