Key Features & Benefits at a Glance
- Vibration-resistant locking: Integrated nylon patch thread locker ensures secure fastening in high-vibration environments, maintaining clamp load from -70° to 250°F
- Exceptional corrosion resistance: 18-8 stainless steel construction provides excellent durability against rust and chemical exposure in harsh industrial settings
- Precision alignment capability: 3/4" shoulder with precise diameter tolerance enables accurate component positioning and smooth rotational movement
- High-strength performance: 70,000 psi tensile strength and Rockwell B55 hardness withstand heavy mechanical loads and repeated assembly cycles
- Secure installation control: Hex socket drive with 3/32" drive size allows high torque application without stripping or cam-out issues
- Reliable thread engagement: Class 2A UNC coarse threads ensure consistent mating with standard nuts and threaded components
- Regulatory compliance assurance: Meets RoHS 3 and REACH environmental standards for global manufacturing applications
Professional Applications & Engineering Value
This precision shoulder screw delivers critical engineering solutions where component alignment and rotational precision are paramount. The 18-8 stainless steel construction combined with the 3/4" shoulder length provides a durable, corrosion-resistant pivot point for machinery assemblies, while the nylon patch thread locker prevents loosening in vibrating equipment. The UNC coarse threads with Class 2A fit ensure rapid assembly in production environments, and the hex socket drive enables high-torque installation in confined spaces. Ideal for precision instruments, rotating mechanisms, and industrial automation systems requiring reliable positioning and vibration resistance.
Specification Summary & Compliance
Manufactured to exacting standards with Class 2A thread fit and precise shoulder diameter tolerance of -0.001" to 0". Features UNC coarse threads (8-32 size) with 3/16" thread length and 3/4" shoulder length with tolerance of 0" to 0.002". Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications worldwide.
