SELF TAPPING THREAD INSERTS ARE USED...

To improve the strength of assemblies by distributing forces from fastener over larger area in base material, thus improving load bearing capability.In material where threads tapped directly get damaged due to torque.In components where wear occurs due to frequent assembly and disassembly.Threaded inserts are used in cast iron, aluminium, light alloy metals and plastic industries for mass production, batch production and thread repairs. Advantages are resistance to vibration, wear, higher strength and easy to install.These inserts are available in steel hardened, brass and stainless steel and are recommended for Light alloyBrass, BronzeCast Iron, Other non Ferrous metalsHard & Soft PlasticsHard Wood.

APPLICATION1. Automabiles industries, Diesel engines, printing machine.2. Machines tools, radiators, gear and flange joints.3. House hold and office equipments.4. Defence, Control systems, Power plants and airplanes.
