About Us:
Sandum/In-saiL offers a wide range of Self Tapping Threaded inserts for Aluminium, cast iron, plastics and NF metals. These available in sizes M2 to M30 and equivalent UNC, UNF and BSW threading. Self Tapping Threaded Insert is designed as a permanent fastener in materials which are of insufficient strength to sustain applied loads in threads tapped directly in to these materials or where thread wear occurs due to frequent assembly and disassembly. The Self Tapping Threaded Insert is a bushing with internal and external threads designed to tap its own threads and is driven into a drilled or cored hole. The thread cutting action is performed by the holes or by the slot on the pilot portion of the inserts.

Features & Benefits include:
Tough and durable due to their substantial wall thickness, their use can reduce the thread size required due to the insert's large effective shear surface. This could save material as well as reduce cost and weight.
They eliminate the need for close tolerance holes required for tapping into the base material, damaged tools and low productivity - they need no special installation tool nor the time consuming process associated with installing a wire thread insert. Holes do not need to be separately tapped as the groove will cut its own thread so long as the correct diameter tolerances for the material and the insert are adhered to.
