Technical Notes
To DIN 8140-1A
These inserts are used for the repair and reinforcement of cracked and damaged threads. Thread inserts are oversized so that when installed they are kept in position by the pressure between the sides of the hole and the coils. These "screw lock" thread inserts (prevailing torque) are useful in applications where there is cyclic vibration or impact. A portion of the thread in the mid area of the insert has polygonal threads and these exert radial pressure on the male thread. It is recommended to use "close fit" thread tolerance male bolts or screws.
Threads are metric coarse threads, other pitches available on request.
Temperature range for use -160° C to +420° C and can withstand temperature surges up to +500° C.
