Description

Engineered for dependable performance in metal assemblies, these Thread Rolling Screws feature a Phillips flat undercut head and are crafted from steel with a black oxide finish and a waxed coating. The Tri-Lobe drive design delivers high torque transfer with reduced cam-out, making them an excellent Taptite screws alternative for many applications.

Highlights

  • Thread-rolling (forming) screws create strong, creep-resistant threads as they are driven, without removing material.
  • Thread-rolling action forms mating threads in the base material for strong, vibration-resistant joints.
  • Phillips flat undercut head sits flush and provides a low-profile finish in recessed assemblies.
  • Tri-Lobe drive enables better torque control and resistance to cam-out compared to traditional drives.
  • Steel with black oxide and waxed finish reduces galling, speeds installation, and improves driving comfort.
  • Size: #4-40 x 1/4" with standard 40 threads per inch.
  • Alternative to Taptite screws for reliable self-tapping performance in metal and sheet-metal projects.

Whether you're repairing, assembling automotive parts, appliances, or metal enclosures, these thread-rolling screws provide a secure fit with a clean, professional finish. Add them to your toolkit for fast, dependable installations.
