Manual Screw Flat Grips

Manual Screw Flat Grips

Screw flat grips are general-purpose grips used for static tensile testing of a wide range of materials, most commonly, rubbers, plastics, textiles, and paper, and specimens such as plates and wires. Another advantage of these grips is they can be used to test thick specimens, up to 16 mm (0.63 in).

There are two types of manual screw flat grips: standard and stainless steel. Standard models have an operational temperature range from -70 to 250°C (-94 to 482°F), whereas stainless steel models are capable of operating over an extended temperature range of -70 to 320°C (-94 to 608°F).

Single-side file-teeth grip faces come standard on 1 kN (220 lbf) and 5 kN (1,100 lbf) capacity grips, and 50 N (11.0 lbf) capacity grips have flat grip faces. Additional grip face options include waves, rubber-coated, high-strength rubber-coated, grip faces for grab tests, and line-contact grip faces. Grip faces are easily exchanged. See the section on Grip Faces for Manual Screw Flat Grips for further information on grip face options.

 

Relevant Materials

Rubber, Plastics, Textiles, Cloth, Paper

 

Relevant Specimens

Plates, Wires

Operation

Manual screw flat grips present a straightforward approach to mounting test specimens. Knurled knobs, adjusted by fingers, tighten the grip faces on the 50 N capacity models. On the higher capacity 1 kN and 5 kN models, the grip faces are closed and opened by a T-wrench.

Note 1: The applicable specimen thickness is valid only for grip faces supplied with the grips and may change when other grip faces are used.

Note 2: The operational temperature range is reduced to between -30 and 200°C (-22 and 392°F) when rubber-coated grip faces are installed.
