Description

Thread Rolling Screws Phillips Flat Head 410 Stainless Steel Tri-Lobe #4-40 X 5/16" screws deliver strong, flush installations with reliable self-tapping performance.

Constructed from 410 stainless steel, they resist corrosion in a variety of environments while forming durable threads without pre-drilling. With a Phillips flat head and a Tri-Lobe drive, these screws seat evenly and provide improved torque transfer, reducing cam-out in tight or confined spaces. The thread-rolling (thread-forming) design creates high-shear strength joints that resist loosening under vibration, making them ideal for assemblies that demand long-term reliability.

Key features include:

  • Material: 410 stainless steel for corrosion resistance and durable performance
  • Head style: Phillips flat head for a flush, professional finish
  • Drive: Tri-Lobe for enhanced grip and reduced cam-out in tight spaces
  • Type: Thread rolling (self-tapping) screws that form threads rather than cutting them
  • Size & length: #4-40 thread size, 5/16" length
  • Alternative: A reliable alternative to Taptite screws for secure assemblies

Applications include electronics enclosures and cabinetry where a flush finish is essential, automotive trims, appliances, consumer electronics assemblies, and industrial enclosures with lightweight metal or plastic panels. These screws deliver a robust, corrosion-resistant solution that combines thread-rolling strength with a clean, low-profile head—ideal for projects requiring reliable performance, long-term durability, and a professional finished look.

Add the Thread Rolling Screws Phillips Flat Head 410 Stainless Steel Tri-Lobe #4-40 X 5/16" to your cart for secure, lasting assemblies.
