Key Features & Benefits at a Glance
- Superior Vibration Resistance – Integrated internal-tooth lock washer prevents loosening under dynamic loads, ensuring long-term joint integrity.
- Excellent Corrosion Protection – 18-8 stainless steel construction with passivated finish resists rust and chemical exposure in harsh environments.
- High Tensile Strength – 70,000 psi rating provides reliable fastening for demanding mechanical assemblies.
- Optimized Drive Engagement – No. 2 Phillips drive offers secure tool engagement and reduces cam-out during installation.
- Precision Thread Fit – Class 2A UNC coarse threads enable quick assembly with consistent clamping force.
- Dual-Material Durability – 410 stainless steel lock washer maintains locking performance without galvanic corrosion.
- Regulatory Compliance Ready – Meets ASME B18.13 specifications and environmental standards for global supply chain integration.
Professional Applications & Engineering Value
These 10-24 UNC rounded head screws with integrated internal-tooth lock washers solve critical vibration-induced loosening in industrial equipment, electronics enclosures, and automotive subassemblies. The 18-8 stainless steel core and passivated finish provide corrosion resistance that outperforms plated carbon steel in humid or chemical-exposed environments. The pan head profile distributes clamp force evenly while the coarse threads reduce cross-threading risks in high-volume production. Engineered for fully threaded engagement, they maintain tension across varying material thicknesses where thread stripping is a concern.
Specification Summary & Compliance
Manufactured to ASME B18.13 standards with Class 2A thread fit tolerance for consistent assembly performance. The UNC coarse threading (10-24) ensures compatibility with standard nuts and tapped holes. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations for hazardous substance restrictions. All components feature passivated finish for enhanced surface durability and corrosion resistance.
