Plastic cap screws are made from nylon PA66 which with distinctive
characteristics compared other screws .
Plastic cap screws has a higher hardness 118 after improved
chemical elements .
Self lubricant make plastic shoulder screws are more resistant wear
and a longer service .
High mechanical property
Resistant high temperature
Normally , plastic nylon cap screws 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 cap screws can be resistant of the most chemicals on
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
Resistance to low temperature
Plastic cap screws can be workable at -30℃
Plastic cap screws meet RoHS or REACH environmental production
Plastic cap screws are widely used to various fields that with
light load and strict conditions on corrosion resistance and
insulation as perfect features .
