Professional Applications & Engineering Value
This nylon insert lock nut delivers critical vibration resistance where conventional fasteners fail. The black corrosion-resistant coated steel construction withstands environmental challenges in automotive, machinery, and outdoor equipment applications. Engineered with UNC coarse threads and Class 2B thread fit, it ensures rapid installation while maintaining precision alignment. The extra-wide thin profile provides maximum wrench contact surface in confined spaces, while the external hex drive accommodates standard tools for maintenance efficiency. With temperature tolerance to 250°F, this lock nut performs reliably in engine compartments, industrial motors, and HVAC systems where thermal cycling and constant vibration demand secure, long-lasting fastening solutions.
Specification Summary & Compliance
This lock nut features 1/4"-20 UNC coarse threads with Class 2B thread fit for consistent engagement and right-hand threading. Dimensions include 1/2" width across flats and 9/32" height for the extra-wide thin profile. Manufactured to industry standards with nylon insert locking mechanism and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety and restricted substances.
