Single-screw testing machines are used primarily for tests in which load-frame stiffness is subject to particularly high demands. Typical applications include low-cycle fatigue tests, creep tests, fracture mechanics tests and tests on springs and ceramics.

• Machine is available in 100 and 250 kN versions.
• Central drive spindle provides a particularly favourable force flow during the test, with direct load application to the specimen.
• Design provides very high load-frame stiffness.
• Modular construction of complete system allows whole Zwick accessory range to be used (e.g. attachment of a wide range of extensometers, specimen grips and load cells).
