M4 x 25mm Torx Cap Head Screws (ISO 14579) - Peek Metric Socket Torx Cap Head Screws feature a cylindrical head and an internal Torx Socket Drive which allows for a more even distribution of force whilst tightening and reduces the chances of cam-out which may cause damage to the screw drive. The Torx drive also allows for a higher torque to be applied to the screw resulting in a more secure fixture. These Torx Cap Head Screws are made from PEEK, which is ideal for use in demanding applications since PEEK has excellent thermal and chemical resistance, as well as a high degree of mechanical strength and stiffness. The material flammability standard of PEEK is UL94 V-0 and the continuous use temperature for this material is 180°C. These Torx Cap Head Screws have been precision manufactured in house from PEEK using state of the art CNC Machines to ISO 14579.
