Characteristics
Plastic hex nuts have higher hardness 118 after improved chemical elements .
Self lubricant make plastic hex nuts are more resistant wear and a longer service .
Normally , plastic hex nuts can be operated smoothly at temperature 150℃ and thermal deformed temperature is up to 250℃ when parts with glass fiber .
Elongation at break is 2.2% according to ISO 527 testing method .
Plastic hex nuts can be resistant of the most chemicals on corrosion .
Specific volume resistance is 1.83×1015 and resistance to high breakdown voltage support part to be good insulated .
60 – 80 KJ/M2 normally .
Generally , the fire resistance is UL94V-2 and UL64V-0 for special parts .
Plastic hex nuts can be workable at -30℃
Plastic hex nuts meet RoHS or REACH environmental production standard .
Application
Plastic hex nuts normally to be used with a threaded shaft or screws to secure objects , a vast application in many fields like
