Lightweight 1 kN screw action grip for films and foils
The UGC-VG-140 is a compact screw action grip for low-force tensile tests on plastic films, textiles and yarns, paper and board, metal foil, and thin aluminum and brass. A pair weighs just 0.75 kg (1.65 lb) without jaws, so it suits small load cells where a heavier grip would eat into the measuring range. Like our larger screw action grips, it is dual-acting and self-tightening, but scaled down for specimens that break at a few hundred newtons.
How it works
Articulating jaws close on the specimen when the screw is turned and then draw tighter as the load rises. Only 4 Nm (35 lbf·in) of torque produces 5 kN (1,124 lbf) of clamping force, five times the grip's 1 kN rating, so a light turn by hand is enough. Both jaws move, which keeps asymmetrical or laminated specimens on the load axis and limits bending at the jaw line. Opening is 0–10 mm depending on the jaws fitted.
Jaws
Standard 30 x 30 mm: blank, rubber, pyramid, fine pyramid, V, wave and diamond
Small 25 x 25 mm: blank, rubber and pyramid
Insert jaws 30 x 30 mm: quick-change faces on carriers
Tall special: 170 mm high body with rubber-coated V-jaws for round specimens, on request
Fine pyramid jaws give a shallower bite for thin metal foil, rubber faces protect film and paper, and wave jaws suit textiles.
Typical applications
Plastic films and foils, textiles and yarns, paper and board, and thin aluminum and brass are the main jobs. The grip suits specimens for film tests such as ASTM D882 and paper strips under ISO 1924-2. The grips are specified for 0 to +70 °C, depending on the jaws.
Machine fit
A 1 kN grip fits the Mark-10 300 lbF tensile tester (about 1.3 kN) or a 2.5 kN Galdabini benchtop machine. The female clevis takes a 15.9 mm (5/8 in) or 20 mm pin, and adapters cover the rest. If you need more force in a light grip, the UGC-VG-110 small U-form vise grip family goes to 2.5 kN in aluminum. Pneumatic versions are listed under pneumatic grips.

Screw Action Grip 1 kN FAQ
How much clamping force does the UGC-VG-140 give?
5 kN (1,124 lbf) at only 4 Nm of screw torque, five times its 1 kN rating.
How heavy is it?
0.75 kg (1.65 lb) per pair without jaws.
Which jaw should I use for metal foil?
Fine pyramid jaws give a shallower bite suited to thin foil. Rubber jaws are better for film and paper.
Can I change jaw faces quickly?
Yes. Quick-change 30 x 30 mm insert jaws mount on carriers, so faces swap without removing the grip.
What is the maximum jaw opening?
Up to 10 mm, depending on the jaws fitted.
Which tester suits a 1 kN grip?
The Mark-10 300 lbF tensile tester is a good match.
