Professional Applications & Engineering Value
This 8-32 x 1/4" flat head Phillips screw is engineered to address critical sealing challenges in industrial assemblies. The combination of 18-8 stainless steel and a Buna-N rubber O-ring creates a durable barrier against fluids and gases, making it ideal for hydraulic systems, pneumatic equipment, and enclosures requiring pressure containment. The undercut flat head profile ensures a secure, flush fit, while the fully threaded UNC coarse design with Class 2A tolerance facilitates quick installation and consistent clamping force. Its ability to withstand temperatures from -40°F to 225°F and pressures up to 1500 psi makes it a reliable choice for automotive, aerospace, and machinery applications where sealing integrity and corrosion resistance are paramount.
Specification Summary & Compliance
This screw features UNC coarse threading with a Class 2A thread fit for precise dimensional accuracy, ensuring reliable engagement in standard applications. It is manufactured from 18-8 stainless steel with a passivated finish to enhance corrosion resistance. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its adherence to environmental and safety standards for industrial use.
