Key Features & Benefits at a Glance
- Superior holding power with a precision-ground alloy steel ball tip that bites into shafts for secure, permanent positioning.
- Exceptional thread precision with a Class 3A fit for reliable, vibration-resistant performance in high-precision assemblies.
- Excellent corrosion resistance provided by 303 Stainless Steel, ideal for use in demanding environments.
- Space-saving headless design allows for flush mounting in confined spaces where a protruding head is not feasible.
- Enhanced torque application with a 3/32" hex drive, enabling secure installation and removal without stripping.
- Optimized for fine adjustments with its 1/4"-100 ultra-fine thread pitch, allowing for precise axial positioning.
- Broad industrial compliance, meeting RoHS 3 and REACH regulations for safe and responsible use.
Professional Applications & Engineering Value
This hex headless set screw is engineered to solve critical challenges in precision machinery and motion control systems. Its ultra-fine thread (1/4"-100) and Class 3A thread fit provide minimal backlash and superior clamping force, preventing loosening under vibration in applications like optical equipment, fine-adjustment collars, and precision gears. The 303 Stainless Steel construction offers good machinability and corrosion resistance, while the alloy steel ball tip ensures maximum grip on hardened shafts without causing galling. This combination delivers reliable, repeatable performance for engineers who cannot compromise on positional accuracy and long-term fixture integrity.
Specification Summary & Compliance
This set screw conforms to UNS (Unified Special) thread standards with a Class 3A tolerance for high-precision external threads. The right-hand thread direction and ultra-fine thread spacing (100 TPI) are manufactured to exacting specifications. The product is fully compliant with RoHS 3 (2015/863/EU) under exemption 6(c) and is REACH (EC 1907/2006) compliant, ensuring it meets stringent environmental and safety regulations for industrial components.
