Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc yellow-chromate plating for extended service life in harsh environments
• High tensile strength performance with Class 8.8 rating (110,000 psi) ensuring reliable load-bearing capacity
• Enhanced stability and load distribution through integrated flange design, eliminating need for separate washers
• Secure torque transmission with external hex drive and 15mm head width for easy installation with standard tools
• Optimized thread engagement with coarse 1.5mm pitch and Class 6g fit for quick assembly and vibration resistance
• Durable material construction featuring Rockwell C22 hardness for excellent wear resistance and mechanical strength
• Versatile partial threading allowing both clamping and alignment functions in diverse assembly applications

Professional Applications & Engineering Value

These M10 hex flange screws deliver exceptional engineering value in demanding industrial environments where corrosion resistance and structural integrity are paramount. The zinc yellow-chromate plated steel construction provides superior protection against oxidation and chemical exposure, significantly extending service life in automotive, machinery, and outdoor equipment applications. The integrated flange design distributes clamping force over a wider surface area (22.3mm diameter), preventing surface damage and maintaining joint integrity under vibration and dynamic loads. With Class 8.8 strength rating and Rockwell C22 hardness, these metric screws withstand extreme mechanical stresses while the coarse thread pitch ensures rapid assembly in production line settings. The partially threaded configuration allows precise positioning and secure fastening in structural frameworks and heavy-duty equipment assemblies.

Specification Summary & Compliance

Manufactured to precise metric dimensions with M10 x 1.5mm coarse thread spacing and Class 6g thread fit tolerance. Complies with ISO 898-1 mechanical properties standard and DIN 6921 flange head specifications. Meets REACH (EC 1907/2006) compliance requirements (June 2023 SVHC assessment) and contains no restricted substances under RoHS directives. The 20mm length with 15mm minimum thread length ensures consistent performance across industrial applications requiring reliable hex head fasteners.
