M4 Slotted Plastic Nylon Set Screw Threaded Bolt for Insert
Plastic set screw is one of plastic fasteners that is similar with metal set screws but for different applications , nylon set screw with a slotted head and flat point , standard metric M4 full threads for inserts .
Nylon set screws are insulated and good ductility , they are made of nylon 66 ( PA 66 ) and meet RoHS requsted UL 94V-2 on fire resistance .
Nylon set screws are named headless set screw as with not head supprting for popular screws bolts , this desgin is help to fasten light working pieces via inserting threaded hole through two different pieces .
