Professional Applications & Engineering Value
These 2-56 UNC nylon patch locking screws solve critical vibration-induced failure points in precision assemblies. The nylon patch thread locker creates permanent friction locking without chemical adhesives, ideal for maintenance-sensitive equipment where disassembly may be required. Manufactured from 18-8 stainless steel with passivated finish, they resist chemical exposure and atmospheric corrosion in industrial environments. The combination of 60,000 psi tensile strength and Rockwell B70 hardness ensures structural integrity in high-stress applications, while the rounded pan head with Phillips drive provides flush mounting and controlled installation. These fully threaded screws are engineered for electronics enclosures, machinery guards, and automotive components where vibration resistance and corrosion protection are paramount.
Specification Summary & Compliance
Precision manufactured to Class 2A thread fit with UNC coarse threading (2-56 size) and compliant with ASME B18.6.3 mechanical standards. Fully meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements. Dimensions include 1/4" length, 0.167" head diameter, and 0.086" thread diameter, ensuring interchangeability with standard components.
