Torx Button Screw M10 x 40mm in A4 Stainless - Sim. ISO 7380

Also known as star, 6 lobe, and hexalobular internal. Torx screws are commonly found on cars, motorcycles, bicycle brake systems, hard disk drives, computer systems and consumer electronics and are becoming increasingly popular. Once, they were typically used in applications requiring tamper resistance; as drivers became more common, tamper-resistant variants were developed. The Torx design allows for a higher torque to be exerted than a similarly sized conventional hex socket head. This button head variant is an attractive screw, typically used where aesthetics are important, or where a lower profile domed finish is required.
