Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments
- Superior thread engagement and reliability through Class 3A thread fit and UNC coarse thread spacing, reducing cross-threading risks
- High mechanical strength with 70,000 psi tensile strength and Rockwell B55 hardness for demanding applications
- Secure and efficient installation using the 0.050" hex drive, preventing tool slippage and ensuring consistent torque application
- Full thread coverage along the 3/16" length for maximum grip and load distribution in assemblies
- Compliant with major industry standards including ASME B18.3, RoHS 3, and REACH for global supply chain compatibility
- Low-profile rounded button head design provides a finished appearance while minimizing protrusion in compact spaces
Professional Applications & Engineering Value
This 1-64 UNC thread rounded head screw delivers critical performance in precision assemblies where material integrity and dimensional accuracy are paramount. The 18-8 stainless steel base material, enhanced by a passivated finish, resists oxidation and chemical exposure in electronics, medical devices, and marine equipment. Its coarse thread spacing and Class 3A thread fit ensure rapid installation with minimal risk of stripping in softer materials or pre-tapped holes. The combination of 70,000 psi tensile strength and a hex drive allows for high clamp loads without compromising the drive recess, reducing assembly time and maintenance cycles in automated production lines.
Specification Summary & Compliance
Manufactured to ASME B18.3 specifications with Class 3A thread tolerances for precise fit. The screw features a 1-64 UNC coarse thread, 3/16" length, and fully threaded design. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) ensures adherence to environmental and safety regulations for industrial components.
