Precision-engineered hexagonal head bolt with detailed thread profile specifications. This drawing presents multiple views including front hex head projection, side profile with complete thread representation, and a detailed cross-section of the threaded portion marked as ‘X Detailed’. Key dimensional parameters are clearly labeled including head width (s), head height (k), thread length (L), bolt diameter (d), thread pitch (P), and fillet radius (r). The fastener follows standard engineering conventions with parameters labeled using, overall, single-letter designations. The thread profile shows precisely formed teeth with consistent pitch spacing, critical for load-bearing applications in mechanical assemblies.
