Key Features & Benefits at a Glance
- Corrosion-resistant nylon plastic construction eliminates rust and galvanic corrosion, ideal for harsh environments and electrical applications
- Wide operating temperature range (-40° to 185° F) ensures reliable performance and dimensional stability in both extreme cold and high-heat conditions
- Class 2A thread fit with UNC coarse threading provides easier, faster assembly and reduced risk of cross-threading for improved production efficiency
- 100° countersink angle and flat head design allows for a flush, secure fit that minimizes protrusion and snagging in assembled products
- Full threading along the 1/2" length offers maximum grip and holding power across the entire fastener for superior joint integrity
- Compliance with ASME B18.6.3, RoHS 3, and REACH guarantees consistent quality, safety, and environmental responsibility for industrial and commercial use
- Slotted drive style enables simple installation and removal with standard tools, reducing assembly time and complexity
Professional Applications & Engineering Value
Engineered for demanding environments, these nylon plastic flat head screws provide a durable, non-conductive, and non-magnetic fastening solution that resists chemicals and corrosion. The 2-56 UNC coarse thread and Class 2A thread fit ensure quick, reliable installation in plastics, composites, and soft metals, reducing assembly errors. The 100° countersink angle and flat head profile deliver a smooth, finished appearance while preventing loosening under vibration. Ideal for electrical enclosures, automotive components, marine hardware, and food processing equipment, these screws maintain integrity across a broad temperature range from -40° to 185° F, offering long-term reliability without the risk of degradation or metallic contamination.
Specification Summary & Compliance
This screw features a 2-56 UNC coarse thread with Class 2A thread fit for consistent dimensional accuracy. It is fully threaded and measures 1/2" in length with a 0.172" head diameter. Manufactured in compliance with ASME B18.6.3 specifications, it also meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safety and regulatory adherence for global industrial applications.
