Key Features & Benefits at a Glance
- Exceptional corrosion resistance with 18-8 stainless steel and passivated finish, ideal for harsh environments and extended service life.
- High tensile strength of 100,000 psi ensures reliable load-bearing capacity and resistance to mechanical stress in demanding applications.
- Precision Class 2A thread fit guarantees smooth assembly and secure fastening, reducing the risk of cross-threading and rework.
- Fine UNF thread design provides superior holding power and vibration resistance in compact or high-precision assemblies.
- Fully threaded shank offers consistent engagement along the entire length, enhancing grip and distribution of clamping force.
- Phillips No. 0 drive allows for efficient installation with standard tools, improving assembly speed and reducing operator fatigue.
- Rounded head profile minimizes protrusion and provides a smooth, finished appearance while reducing snagging risks.
Professional Applications & Engineering Value
Engineered for precision and durability, these 18-8 stainless steel rounded head screws with 0-80 UNF fine threads address critical challenges in industrial settings, such as vibration loosening and corrosion-induced failure. The passivated finish enhances surface integrity, preventing galling and seizing during installation in tight-tolerance components. With a Rockwell B100 hardness and 100,000 psi tensile strength, they withstand high-stress conditions in electronics, instrumentation, and machinery assemblies. The fully threaded design and Class 2A thread fit ensure uniform load distribution and reliable performance in applications requiring repeated disassembly, reducing maintenance downtime and improving operational efficiency.
Specification Summary & Compliance
This screw features a 0-80 UNF fine thread with Class 2A thread fit for precise dimensional accuracy, manufactured in compliance with ASME B18.6.3 standards. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulatory requirements, ensuring environmental and safety adherence for global industrial use.
