• Precise mechanical properties featuring Rockwell C32 hardness for consistent durability and resistance to deformation
• Efficient installation and removal with external hex drive and 36mm head width providing excellent tool access and torque transmission
• Versatile partial threading design (54mm min thread length on 90mm shank) offering flexibility for applications requiring both threaded and unthreaded sections
• Guaranteed dimensional accuracy with Class 6h thread fit ensuring consistent performance and interchangeability

Professional Applications & Engineering Value

These M24 hex head screws deliver critical engineering solutions for heavy-duty industrial applications where failure is not an option. The Class 10.9 steel construction provides exceptional structural integrity for construction frameworks, machinery assembly, and infrastructure projects requiring high tensile strength. The zinc yellow-chromate plating creates a protective barrier against corrosion in outdoor or chemically aggressive environments, significantly extending maintenance intervals. With metric coarse threading (3mm pitch), these partially threaded fasteners offer superior pull-out resistance while allowing for precise clamping force control. The external hex drive design ensures compatibility with standard tools, streamlining installation in confined spaces common in industrial equipment and structural steel connections.

Specification Summary & Compliance

Manufactured to ISO 4014 specifications (equivalent to DIN 931) with Class 6h thread fit tolerance ensuring precise dimensional accuracy. These metric hex head screws feature M24 x 3mm coarse threads with right-hand direction and partial threading (minimum 54mm thread length on 90mm overall length). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications with strict chemical substance restrictions.
