Clear Plastic Screws Round Head Fastener M5 Full Thread Slotted Cross Drive
Plastic round head screws are designed as phillips slot drive for multiple operation by a phillips drive screw driver bits or a slot driver screw driver bits ; Full threads to under head which makes screws are more good on secure .
Plastic round head screws are made from plastic PC (Polycarbonate ) material , apparent with good fire resistance .
Plastic PC round head screws are a good choice for items that with high tensile strength and fireproof and light transmittance requests as individual performances .
