For high-force tensile testing of metallic specimens on this universal testing machine, the recommended approach is to use high-load wedge-style gripping, most commonly hydraulic wedge grips, sized to match your specimen geometry and expected peak load. This style of grip is well-suited for securely clamping smooth or ribbed, round or flat metal samples while maintaining alignment during yield and fracture.

Grip selection is typically driven by a few practical factors:

• Specimen type and surface condition, for example smooth round bars versus ribbed rebar, and whether serrated or specialty jaw faces are needed.
• Specimen size range, including diameter for round specimens and thickness for flat specimens, so the correct jaw set and grip body are selected.
• Target force level and test method, so the grip capacity and clamping style match the frame capacity and the way the load is applied.
• Test workflow, including how often you change specimen sizes and whether faster, repeatable hydraulic clamping is preferred.
