Professional Applications & Engineering Value
These 3-56 UNF socket head cap screws deliver critical performance advantages in precision engineering applications where space constraints and reliability are paramount. The black-oxide alloy steel construction combined with Class 3A fine threads addresses common industrial challenges including vibration loosening, corrosion in demanding environments, and the need for consistent clamping force in compact assemblies. The fully threaded design ensures maximum engagement in shallow mounting scenarios, while the standardized hex drive system facilitates efficient installation in confined spaces typical of machinery, electronics, and precision equipment where high tensile strength and dimensional accuracy are non-negotiable requirements.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 3A thread fit for superior engagement in UNF fine thread applications. These socket head cap screws conform to ASTM A574 specification for alloy steel socket head cap screws, ensuring consistent quality and performance. The products are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, meeting the latest industry standards for restricted substances and chemical safety in industrial components.
