S-91180A802 M14 x 120 mm ISO 8765, DIN 960 Medium-Strength Metric Class 8.8 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capacity with 110,000 psi tensile strength and Class 8.8 grade for reliable performance in high-stress industrial environments.
• Superior corrosion resistance provided by zinc plating, extending service life in humid or outdoor applications.
• Precise fine thread engagement with M14 x 1.5 mm pitch and Class 6h fit ensuring secure, vibration-resistant connections.
• Optimized partial threading design allowing for controlled clamping force and reduced risk of thread damage during installation.
• Robust Rockwell C21 hardness maintaining structural integrity under repeated mechanical stress and impact loads.
• Industry-standard external hex drive enabling efficient torque application with common tools while preventing cam-out.
• Global compliance assurance meeting ISO 8765 (DIN 960), RoHS 3, and REACH standards for cross-border project compatibility.

Professional Applications & Engineering Value

Engineered for demanding industrial fastening scenarios, these M14 hex head screws solve critical challenges in machinery assembly, structural steel connections, and heavy equipment manufacturing. The Class 8.8 steel construction delivers consistent yield strength where dynamic loads or vibration fatigue would compromise inferior fasteners. Partially threaded geometry concentrates stress away from shear planes while the fine metric thread pitch provides superior resistance to loosening in high-cycle applications. Zinc-plated surface treatment creates a sacrificial barrier against galvanic corrosion in chemical processing or marine-adjacent environments, reducing maintenance intervals and replacement costs. These screws are specified by engineers requiring ISO 8765 compliance for international project approvals without sacrificing mechanical performance.

Specification Summary & Compliance

Manufactured to ISO 8765 (DIN 960) dimensional standards with Class 6h thread tolerance ensuring interchangeability. The M14 x 1.5 mm fine pitch threads maintain precise engagement across the 34 mm minimum threaded portion. Full compliance with RoHS 3 (2015/863/EU) hazardous substance restrictions and REACH (EC 1907/2006) chemical safety protocols validates environmental responsibility. Class 8.8 mechanical properties are certified to deliver specified tensile strength and hardness values per international metric fastener specifications.
