Professional Applications & Engineering Value
Engineered for demanding industrial settings, these 2-56 UNC rounded head binding screws address critical needs in electronics, instrumentation, and machinery assembly. The 18-8 Stainless Steel material, combined with a passivated finish, resists oxidation and chemical exposure, prolonging service life in humid or corrosive conditions. The wide rounded head profile distributes clamping force evenly, protecting components from indentation, while the coarse UNC threads and Class 2A fit facilitate rapid installation with minimal alignment errors. Ideal for binding posts, panel fastening, and electrical enclosures, these screws deliver reliable performance where precision, strength, and environmental compliance are paramount.
Specification Summary & Compliance
This binding screw features a 2-56 UNC thread size with Class 2A tolerance for consistent fit, coarse thread spacing, and right-hand direction. It meets ASME B18.6.3 manufacturing specifications and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe and sustainable use.
