Key Features & Benefits at a Glance
- Superior corrosion resistance from brass material, ideal for harsh or humid environments without compromising integrity.
- High tensile strength of 50,000 psi ensures reliable load-bearing capacity and reduces risk of failure under stress.
- Rockwell B40 hardness provides excellent durability and wear resistance for long-term use in mechanical assemblies.
- Class 2A thread fit with UNC coarse threading allows for quick, secure installation and easy disassembly in right-hand applications.
- Fillister head with high, narrow profile and slotted drive offers a low-profile design for tight spaces and simple tool engagement.
- Full compliance with ASME B18.6.3 guarantees dimensional accuracy and interchangeability in precision engineering projects.
- RoHS 3 and REACH compliant ensures environmental safety and regulatory adherence for global supply chains.
Professional Applications & Engineering Value
This 2-56 UNC brass Fillister head slotted screw is engineered to address common industrial challenges such as corrosion, vibration loosening, and space constraints. The brass material naturally resists rust and oxidation, making it ideal for electrical enclosures, marine equipment, and plumbing systems where moisture is a concern. Its coarse UNC threading and Class 2A fit provide a secure hold in softer materials or pre-tapped holes, reducing the need for frequent maintenance. The high, narrow rounded head and slotted drive style allow for efficient installation in confined areas, while the fully threaded design ensures consistent clamping force. These features make it a reliable choice for OEM assemblies, instrumentation, and consumer electronics that demand precision, durability, and regulatory compliance.
Specification Summary & Compliance
This screw adheres to inch system measurements with a 1/4" length, 2-56 UNC thread size, and Class 2A thread fit for precise dimensional tolerance. It meets ASME B18.6.3 specifications for machine screws, ensuring consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting safe and sustainable manufacturing practices.
