Discover more about the Torx Cap Head Screws range
Torx Cap Screws feature a hexalobular Torx drive (also commonly known as star drive or 6lobe), which aids torque transmission and prevents cam-out. Torx Cap Head Screws Feature a cylindrical head, and are commonly used in a wide number of applications. All of Accu’s Hexalobular Cap Screws are compatible with our Hexalobular Torx Drive Bits.
All Hexalobular Cap Screws are manufactured in accordance with ISO 14579, and are precision machined to achieve a general tolerance of ±0.13mm. Accu's fasteners have a maximum thread length, which will be specified in the technical specification of each individual component.
