POLYCARBONATE plastic fastener [ JAPAN ]

PC (polycarbonate) is a non-crystalline engineering plastic. It has excellent impact resistance and balanced mechanical properties and electrical properties. Moreover, because it is transparent and self extinguishing, it is used in wide range of fields such as electrical and electronic area, automobiles and medical.

It does not contain any of the 6 substances restricted by RoHS. (Lead, cadmium, mercury, hexavalent chrome, PBB, PBDE).

Continuous use temperature 115°C

Combustibleness UL94 HB

PC(polycarbonate) (+)FLAT HEAD SCREWS

Size list and Quantity

Please use torque driver or torque wrench for fastening. Recommended fastening torque is 50% of breaking torque value under actual use conditions.
Since heat resistance and chemical resistance changes according to use conditions, ensure to test under actual use conditions beforehand.
Exposure to water or vapor at high temperatures may significantly reduce the mechanical strength due to hydrolysis. Therefore, avoid exposure to water or vapor at high temperatures.
Avoid exposure to ammonia as it accelerates hydrolysis.
Exposure to organic solvents or oils may cause cracks even at low stress. Moreover, cracks may be caused by plasticizing agents contained in rubber and PVC (Polyvinyl Chloride). Therefore, avoid exposure to organic solvents, oils, rubber and PVC.
Black spots (sludge) may appear on the external surface. However, this has no impact on performance.
Gate residue of screw head is 0.2mm or less.
Discoloration to some extent may occur depending on lot and various conditions.
Size available in stock, configuration and manufacturers of raw materials used may change without any notice.

The polycarbonate screw is used in the masking of the threaded hole at the time of the alumite processing. The polycarbonate screw is superior to a nylon screw.

The polycarbonate screw is used for the insulation of the electronic board.
