About the Pan Head Hexalobular Socket Screw, M6
This Pan Head Hexalobular Socket Screw M6 x 40 is a metric machine screw with a low-profile pan head and a hexalobular (six-lobe, TX-type) internal drive, supplied with a fully threaded shank. It is manufactured from property class 8.8 carbon steel — the widely used medium-strength bolting class whose nominal tensile strength is 800 MPa under ISO 898-1 — and is zinc plated for basic corrosion protection in dry, indoor or otherwise protected service. The hexalobular recess allows high installation torque to be transmitted with minimal cam-out and low bit wear, which suits powered and repeated assembly better than cross-recess drives. The product name references an ISO specification for this head form. Full threading over the 40 mm length allows clamping into tapped holes and inserts at any engagement depth up to the screw length.
