Key Features & Benefits at a Glance
- Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction and passivated surface treatment
- High mechanical strength and reliability with a tensile strength of 70,000 psi for demanding industrial applications
- Secure, flush-mount installation provided by the wide button head design and integrated flange, eliminating the need for a separate washer
- Efficient assembly and disassembly enabled by the internal hex drive (3 mm), allowing for high torque application in confined spaces
- Excellent thread engagement and vibration resistance from the fully threaded M5 coarse thread (0.8 mm pitch) with Class 6g fit
- Guaranteed dimensional interchangeability and quality assurance through strict adherence to the ISO 7380 standard
- Safe for sensitive applications with full compliance to RoHS 3 and REACH environmental regulations
Professional Applications & Engineering Value
This 316 stainless steel flanged button head screw is engineered to solve critical challenges in corrosive and high-strength applications. The combination of M5 coarse threading and a Class 6g thread fit ensures rapid assembly and reliable performance in vibrating machinery, from food processing equipment to marine hardware. The integrated flange distributes clamping force over a wider area (11.8 mm diameter), protecting soft materials and simplifying inventory by removing the need for separate washers. The passivated finish on the 316 stainless steel significantly enhances its resistance to chemicals and saltwater, making it an ideal, durable metric screw for outdoor, chemical, and marine engineering projects where failure is not an option.
Specification Summary & Compliance
This screw conforms to the dimensional and mechanical specifications of ISO 7380. The metric thread is M5 x 0.8 mm with a Class 6g tolerance and is fully threaded along its 25 mm length. It is manufactured from 316 Stainless Steel with a Passivated finish. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations.
