Professional Applications & Engineering Value

This No. 4-24 thread forming screw delivers exceptional engineering value for plastic assembly applications where material integrity is paramount. The 18-8 stainless steel construction provides excellent corrosion resistance while the thread forming technology eliminates the need for tapping operations, creating strong, load-bearing threads that won't strip or loosen under vibration. The Phillips drive system ensures efficient installation with standard tools, while the pan head design offers a low-profile finish that's ideal for consumer products, electronic enclosures, and automotive plastic components. The blunt tip and precise threading prevent plastic cracking during installation, making it perfect for thin-walled plastic assemblies where material stress must be minimized.
