- Superior corrosion resistance from zinc-plated steel coating prolongs service life in harsh industrial environments.
- Secure locking mechanism with serrations on the flange prevents loosening under vibration, maintaining joint integrity.
- Precise fastening with UNF fine threading and Class 2A thread fit allows for accurate installation and reduced cross-threading.
- High durability backed by Rockwell C22 hardness and Grade 5 classification for consistent performance under stress.
- Easy installation and removal with external hex drive design, compatible with standard tools for efficient maintenance.
- Full threading along the 1 1/2" length provides uniform grip and distribution of load across the fastener.
Professional Applications & Engineering Value
This Grade 5 zinc-plated steel hex head screw is engineered to address common industrial challenges, such as vibration-induced loosening and corrosion in demanding environments. The UNF fine thread and Class 2A fit ensure tight, precise connections in machinery, automotive assemblies, and structural frameworks, minimizing the need for re-tightening. The flanged design with serrations enhances locking capability, making it ideal for applications where safety and reliability are critical. By combining high tensile strength and compliant surface treatment, it offers long-term value in heavy-duty fastening scenarios, reducing maintenance costs and downtime.
Specification Summary & Compliance
This screw adheres to Class 2A thread fit for consistent dimensional accuracy and meets SAE J429 specifications for Grade 5 fasteners. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material integrity in industrial use.
