Zhuocheng button head six lobe Torx half thread screw with flat washer

Also known as Torx Head Cap Screws or Allen Bolts, these screws have a cylindrical head with a six-lobe socket drive which has more resistance to cam out and can be used with power drivers – enabling faster use and higher torque to be achieved.It's characterised by a distinct, 6-point star-shaped pattern and is often called a 'star screw' that requires a 'star screwdriver' with a 'star bit' to tighten and untighten them. Torx screws are typically used in vehicles, motorcycles, bicycles, computer systems, hard disk drives and consumer electronics.The Star (also known as Torx) has a six-point, star-shaped drive that was developed mainly to enhance tamper resistance and ensure snug fits. The star design drivers cut down on the risk stripping the screw heads, slippage, or cam-outs, with tight, specific fits.
