Professional Applications & Engineering Value
This 2-56 nylon insert locknut delivers critical vibration resistance where conventional fasteners fail. The black-oxide 18-8 stainless steel construction provides dual protection against corrosion and galling, while the nylon insert locking mechanism creates consistent friction that prevents loosening from machinery vibrations. Engineered with UNC coarse threads and external hex drive, it enables rapid installation in automotive assemblies, electrical enclosures, and industrial equipment where thermal cycling up to 220°F occurs. The Class 2B thread fit ensures reliable engagement without binding, reducing assembly time and preventing thread damage in high-volume production environments.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2B thread fit and UNC coarse threading (2-56 size). The locknut features 1/4" width across flats and 9/64" height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance. The nylon insert maintains locking performance within its specified temperature range while the black-oxide surface treatment enhances durability in various industrial conditions.
