Key Features & Benefits at a Glance
- Superior corrosion resistance with passivated 18-8 stainless steel construction, ensuring long-term reliability in harsh environments.
- Enhanced security and tamper resistance via the T8 Torx drive, preventing unauthorized access in sensitive applications.
- Reliable fluid and gas sealing up to 1500 psi, thanks to the integrated Buna-N rubber O-ring that maintains integrity from -40° to 225°F.
- Consistent thread engagement and assembly precision with Class 6g thread fit and full threading, reducing installation errors.
- High tensile strength (100,000 psi) and durability from Rockwell B96 hardness, supporting heavy-duty mechanical loads.
- Broad temperature and chemical compatibility with the Buna-N O-ring, suitable for varied industrial conditions.
- Streamlined procurement and compliance by meeting ASTM F879M, ISO 7380, RoHS 3, and REACH standards.
Professional Applications & Engineering Value
This M3 metric screw with a passivated 18-8 stainless steel body and tamper-resistant Torx drive addresses critical needs in industrial sealing applications, such as machinery enclosures, fluid systems, and electronic housings. The Buna-N rubber O-ring ensures leak-proof performance under pressures up to 1500 psi and across a wide temperature range (-40° to 225°F), preventing fluid ingress and corrosion. Its fully threaded design and Class 6g thread fit provide secure fastening in metric coarse threading scenarios, reducing vibration loosening and enhancing assembly efficiency. Ideal for demanding environments where reliability, security, and regulatory compliance are paramount.
Specification Summary & Compliance
This screw features M3 x 0.5 mm coarse threading with a Class 6g thread fit for precise dimensional accuracy, and it is manufactured to ASTM F879M and ISO 7380 specifications. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring adherence to environmental and safety regulations for industrial use.
