Often copied, never equalled: the original malleable cast iron screw clamps from BESSEY the classic screw clamps dating back to 1936. Unmistakable, thanks to their unique high-quality profiled rail and their characteristic malleable cast iron arms, serrated for reinforcement. The integrated BESSEY anti-slip system additionally ensures maximum safety. This is why the original BESSEY malleable cast iron screw clamps have proved so successful for so many years. And so ideal for all applications where powerful, rigid clamping is required. Try them out for yourself! Your benefits at a glance:1 Integrated BESSEY anti-slip system.Maximum safety is available with the integrated BESSEY anti-slip system, when clamping with a throat depth of 80 mm or more. A set screw that is molded into the sliding arm interlocks with the serration on the rail. This effectively prevents the clamp from dislodging or slipping away. 2 Reinforced malleable cast iron arms.The characteristic high-quality malleable cast iron fixed and sliding arms, which are serrated for reinforcement, allow powerful, rigid clamping. The powder coating provides additional protection against corrosion. 3 High-quality profiled rail.The BESSEY profiled rail from our own drawing plant has been especially optimised for clamps. The profile acts as a reliable reinforcement against torsional forces, while the serration on six faces additionally prevents the clamp from slipping. 4 Smooth-running spindle.The surface-coated spindle with acme thread is particularly smooth-running, and does not bind. For even smoother, more efficient work. Noticeably more comfortable.The Bessey TG12 Malleable Cast Iron Screwclamp has the following specification: Clamping Force: up to 6,000N.Opening 120mm.Throat Depth: 60mm.Rail: 20 x 5mm.Weight: 0.42kg.
