S-94309A414 M12 Thumb Nuts

Key Features & Benefits at a Glance

• Hand-tightened efficiency - Wing-shaped head design allows for quick installation and removal without tools, saving time in maintenance and assembly applications.
• Superior corrosion resistance - Zinc-plated steel construction provides reliable protection against rust and environmental degradation in industrial settings.
• Precision thread engagement - Class 6H thread fit ensures consistent, secure fastening with minimal risk of cross-threading or loosening under vibration.
• Heavy-duty load capacity - M12 coarse threading (1.75mm pitch) delivers excellent holding power for demanding mechanical applications.
• Optimal grip surface - 76.2mm width across wings combined with 24.5mm base diameter provides comfortable, slip-resistant handling even with gloves.
• Regulatory compliance assurance - Meets RoHS 3 and REACH standards, making them suitable for regulated industries and international supply chains.
• Metric system compatibility - Right-hand metric threading ensures seamless integration with existing metric equipment and components.

Professional Applications & Engineering Value

This zinc-plated steel thumb nut addresses critical industrial fastening challenges where tool access is limited or rapid disassembly is required. The M12 coarse thread configuration with 1.75mm pitch provides exceptional vibration resistance while the Class 6H thread fit maintains precise tolerances for repeated use without galling. Engineers specify these wing thumb nuts for machinery guards, electrical enclosures, and agricultural equipment where corrosion-resistant hand-tightened fasteners must withstand harsh environments. The combination of 24.5mm base diameter and 76.2mm wing span creates an optimal leverage ratio for both initial tightening and maintenance accessibility, eliminating the need for specialized tools in confined spaces.

Specification Summary & Compliance

Manufactured to metric standards with Class 6H thread fit precision and right-hand coarse threading (M12 x 1.75mm). The zinc-plated steel construction meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements. Physical dimensions include 24.5mm base diameter, 76.2mm width across wings, and 19.1mm height. Suitable for industrial applications requiring reliable, hand-operated fastening solutions with consistent dimensional accuracy.
