S-91280A181 M10 x 190 mm ISO 4014, DIN 931 Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior load-bearing capacity with Class 8.8 strength grade and 110,000 psi tensile strength for reliable performance in high-stress applications
• Enhanced corrosion resistance through zinc plating, extending service life in demanding industrial environments
• Optimized thread engagement with M10 coarse thread (1.5 mm pitch) ensuring faster assembly and reduced cross-threading risks
• Precise mechanical compatibility meeting ISO 4014 specifications (equivalent to DIN 931) for guaranteed interchangeability
• Secure external hex drive providing maximum torque transmission and preventing tool slippage during installation
• Strategic partial threading allowing unthreaded shank sections to bear shear loads while maintaining clamping force
• Environmental compliance assurance with RoHS 3 and REACH standards for safe use across regulated industries

Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M10 hex head screws combine Class 8.8 steel construction with zinc plating to address critical challenges in heavy machinery, structural steel connections, and equipment manufacturing. The partially threaded design provides an unthreaded bearing surface that resists shear forces while the threaded portion maintains precise clamping pressure. With coarse metric threading (1.5 mm pitch), installation is accelerated while minimizing thread damage in high-vibration environments. The external hex drive ensures maximum torque application without cam-out, making these ISO 4014 compliant fasteners ideal for construction projects, industrial assembly lines, and maintenance operations where reliability and corrosion resistance are paramount.

Specification Summary & Compliance

This 190 mm length hex head screw features M10 x 1.5 mm coarse thread with Class 6h thread fit ensuring precise dimensional accuracy. Manufactured to ISO 4014 specifications (equivalent to DIN 931) with Class 8.8 strength grade, Rockwell C21 hardness, and 110,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
