S-95150A156 3/8"-16 Thumb Nuts

Key Features & Benefits at a Glance

• Enhanced manual torque application through the flanged profile and knurled round head for superior grip without tools
• Corrosion-resistant performance in demanding environments due to Black-Oxide coated 18-8 Stainless Steel construction
• Quick and secure coarse threading with 3/8"-16 UNC fully threaded design for rapid assembly and disassembly
• Reliable thread engagement ensured by Class 2B fit, providing consistent fastening in industrial applications
• Increased bearing surface area from the 5/8" collar diameter, distributing load and reducing material stress
• Compliance with environmental standards including REACH and RoHS 3 for safe use across regulated industries
• Optimized for right-hand threading systems compatible with standard UNC components and equipment

Professional Applications & Engineering Value

This flanged thumb nut solves critical hand-tightening challenges in maintenance-heavy and tool-limited environments. The Black-Oxide 18-8 Stainless Steel construction resists corrosion while the knurled round head provides exceptional grip even with oily hands or gloves. Its 3/8"-16 UNC coarse threading enables rapid installation on machinery, conveyor systems, and electrical enclosures where frequent adjustments are needed. The integrated flange acts as a built-in washer, preventing loosening from vibration and protecting sensitive surfaces from damage. Engineers specify this component for assembly stations, field service kits, and OEM equipment requiring reliable, tool-free fastening that maintains integrity under repeated use.
