Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 stainless steel construction and passivated finish, ideal for harsh industrial environments.
- Exceptional mechanical strength offering 100,000 psi tensile strength and Rockwell B100 hardness for reliable, long-term fastening.
- Easy installation and removal with a slotted drive style and wide rounded binding head for secure, tool-accessible assembly.
- Precise thread engagement through UNC coarse threading and Class 2A fit, ensuring consistent performance and reduced cross-threading risk.
- Full-threaded design maximizes grip and load distribution across the entire 3/8" length for enhanced joint integrity.
- Broad regulatory compliance meets ASME B18.6.3, RoHS 3, and REACH standards, supporting global supply chain requirements.
- Durable binding head profile provides a wide bearing surface to prevent pull-through in soft materials or electronic panels.
Professional Applications & Engineering Value
This 2-56 UNC rounded head binding screw is engineered to address critical fastening challenges in precision assemblies, such as electronics, instrumentation, and machinery panels. The 18-8 stainless steel material, combined with a passivated finish, resists oxidation and chemical exposure, extending service life in demanding conditions. Its coarse UNC thread and Class 2A fit enable quick, secure installation with minimal risk of stripping, while the binding head style distributes clamping force effectively to protect sensitive components. Fully threaded along its 3/8" length, it ensures uniform stress distribution, making it a reliable choice for applications requiring vibration resistance and repeated disassembly.
Specification Summary & Compliance
The screw features a 2-56 UNC thread size with Class 2A thread fit for precise dimensional accuracy, as per ASME B18.6.3 specifications. It is manufactured from 18-8 stainless steel with a passivated finish, and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental and safety standards are met for industrial use.
