Professional Applications & Engineering Value
This Grade 2 steel thin hex nut addresses critical engineering challenges in industrial assembly where space constraints and vibration resistance are paramount. The UNF fine thread configuration (1 1/8"-12) provides superior clamping force distribution compared to coarse threads, making it ideal for precision equipment, machinery components, and automotive systems requiring stable, long-term fastening solutions. The thin hex profile reduces weight and material usage while maintaining full wrench engagement across its 1 11/16" width. Manufactured from carbon steel with right-hand threading, this fastener delivers consistent performance in maintenance, repair, and OEM applications where reliability cannot be compromised.
Specification Summary & Compliance
This hex nut maintains Class 2B thread tolerance per UNF standards, ensuring precise thread engagement and interchangeability. The 1 1/8"-12 UNF fine thread specification guarantees compatibility with matching male threads. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives, confirming the absence of restricted hazardous substances. Dimensions include 1 11/16" width across flats and 39/64" height, conforming to inch system standards for North American industrial applications.
