• High-torque installation capability via 3/16" hex drive design, allowing secure seating without head interference
• Temperature-resistant performance with nylon tip maintaining integrity from -50° to 250°F (-45° to 121°C)
• Optimized for coarse-thread applications using 3/8"-16 UNC threads for rapid installation in softer materials
• Regulatory compliance assurance meeting ASME B18.3, RoHS 3, and REACH standards for global industrial use

Professional Applications & Engineering Value

This headless set screw delivers exceptional value in precision machinery and assembly applications where space constraints and vibration resistance are critical. The black-oxide alloy steel construction provides excellent durability while the Rockwell C28 hardness ensures reliable performance under repeated torque cycles. The green nylon 6/6 plastic tip creates a secure, mar-free locking action that prevents damage to shaft surfaces while maintaining grip under thermal cycling from -50° to 250°F. The Class 3A thread fit with 3/8"-16 UNC coarse threads enables quick installation in pulleys, gears, and collars while the 3/16" hex drive accommodates standard industrial tools for consistent torque application in automated assembly environments.
