Discover more about the Metric Torx Countersunk Screws range.
Torx Countersunk Screws feature a hexalobular Torx drive, also known as Star and 6lobe, which prevents cam-out, even under high-torque operation. Torx screws are commonly used for their ability to effectively transmit torque.
Countersunk screws, sometimes denoted by the abbreviation 'CSK', feature an angled countersunk head, which is designed to fit within a countersink. Countersunk screws are designed for use alongside pre-drilled countersunk holes, and are designed to sit flush with the target housing. ‘Countersunk’ is commonly abbreviated to ‘CSK’ in many part numbers and product descriptions.
