Key Features & Benefits at a Glance
- Superior corrosion resistance with cadmium plating that protects against rust and extends service life in demanding environments
- Excellent holding power from fully threaded coarse UNC design that provides faster installation and secure fastening in various materials
- High tensile strength rating of 60,000 psi ensures reliable performance under substantial mechanical stress and vibration
- Precise Class 2A thread fit guarantees consistent engagement and reduces cross-threading risks during assembly
- Optimized Phillips No. 1 drive allows for efficient torque application while the rounded pan head sits flush for clean aesthetics
- Rockwell B69 hardness maintains thread integrity and prevents stripping under repeated use
- Full compliance with Fed. Spec. FF-S-92 ensures consistent quality and reliability for government and industrial applications
Professional Applications & Engineering Value
These 4-40 UNC cadmium-plated steel screws deliver critical performance where corrosion resistance and mechanical reliability are paramount. The rounded pan head design with Phillips No. 1 drive provides a low-profile solution that withstands vibration while allowing efficient installation in confined spaces. The fully threaded coarse UNC pattern ensures maximum thread engagement in softer materials and plastics, preventing pull-out failures. With 60,000 psi tensile strength and Rockwell B69 hardness, these fasteners maintain clamping force in high-stress assemblies across aerospace, electronics, and machinery applications where Fed. Spec. FF-S-92 compliance is required.
Specification Summary & Compliance
This 3/16" length screw features precision 4-40 UNC coarse threads with Class 2A thread fit tolerances for consistent mating. Manufactured from cadmium-plated steel with right-hand threading and fully threaded design. Complies with Fed. Spec. FF-S-92 (MS35206-212) manufacturing standards, ensuring dimensional accuracy and performance consistency for industrial and government applications.
