Made of 303 stainless steel: The reducing nut is made of durable 303 stainless steel, which is resistant to high temperature, strong and wear-resistant Wide Application: Repair nuts are industrial fastening parts, mostly used with screws or bolts. If there is a thread error or to repair a damaged threaded hole, the repair nut can be used to effectively repair the threaded hole Use suggestion: If the M8 thread is very slippery, if you want to continue to use the M8 thread after repair, please use this method to enlarge the M8 thread to M10 thread, and then use the M8-M10 length reducer to change it back to M8, because this can reduce the diameter. The material is stainless steel, which will make the M8 thread stronger Wide range of applications: These repair nuts are widely used in manufacturing fields such as aviation, automobiles, electronic communications, computers, molds, mechanical equipment, etc. Thread size standard: internal thread M8 x 1.25; external thread M10 x 1.5; length: about 12 mm/0.5 inches. The thread is clear and the thread slip repair is more accurate
