Key Features & Benefits at a Glance
- Superior corrosion resistance thanks to 18-8 Stainless Steel construction and passivated finish, ideal for harsh environments.
- Excellent tensile strength rated at 100,000 psi ensures reliable, high-load fastening without failure.
- Optimized for quick assembly with coarse UNC threading and Class 2A fit, reducing installation time and cross-threading risks.
- Secure, flush seating provided by the rounded head profile and standard Phillips No. 0 drive, minimizing protrusion and slippage.
- Consistent performance and interchangeability guaranteed by full compliance with ASME B18.6.3 dimensional standards.
- Enhanced durability and material integrity from Rockwell B100 hardness, resisting wear and deformation.
- Safe for regulated industries with full RoHS 3 and REACH compliance, meeting strict environmental and health standards.
Professional Applications & Engineering Value
These 1-64 UNC coarse thread screws are precision-engineered from 18-8 Stainless Steel to address common industrial challenges like corrosion, vibration loosening, and assembly efficiency. The passivated finish significantly enhances surface resistance to oxidation and chemical exposure, making these rounded head screws ideal for electronics, instrumentation, and marine applications. The coarse thread and Class 2A fit ensure rapid installation and reliable grip in softer materials or where repeated disassembly is required. Combined with a Phillips drive for controlled torque application, they deliver consistent, vibration-resistant fastening that maintains integrity under stress, reducing maintenance needs and downtime in demanding industrial fastener systems.
Specification Summary & Compliance
This screw features a 1-64 UNC coarse thread with Class 2A thread fit for standard inch-system tolerances, ensuring precise engagement. It is fully threaded and right-hand threaded for uniform load distribution. Manufacturing and dimensional compliance adhere to ASME B18.6.3, with material and finish meeting RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, confirming environmental safety and material restrictions compliance.
