Description
These #4-40 x 3/8" thread rolling screws form their own mating threads as they are driven, using a tri-lobular shank that displaces material rather than cutting it. They are a direct alternative to Taptite screws, built from 18/8 Stainless Steel with a black oxide finish, with a flat head and a phillips drive.
- Material and finish: 18/8 Stainless Steel Black Oxide
- Head style: Flat
- Drive: Phillips
- Thread form: Tri-Lobe, Taptite alternative
- Thread size: #4-40
- Length: 3/8"
- Applications: Thread forming into untapped holes in metal assemblies
Rolling the thread instead of cutting it leaves no chips to clear and work-hardens the mating material, which raises pull-out strength and resistance to vibration loosening. Hole size matters: follow the manufacturer recommended pilot hole for the material and thickness being fastened.
