Variants and Design Specifics Not all screws that tap are created equal, and understanding the specific variants is crucial for selecting the right product for the application. If the hole is too small, the excess material can cause the screw to seize or snap.
Tapping Screw Thread Forming Categories and Design Variants
To endure the high torsional stresses and friction involved, these fasteners are typically manufactured from alloy steel, stainless steel, or titanium, often treated with zinc or black oxide coatings to prevent corrosion and galling. The pilot hole diameter is critical; if it is too large, the screw will not generate sufficient thread engagement, leading to a weak joint.
This process is distinct from drilling, as it relies on plastic deformation rather than simple material removal. In the electronics industry, they secure delicate circuit boards and housing components where nuts would be impractical.
Tapping Screw Thread Forming Categories and Design Variants
Unlike a standard machine screw that requires a nut or a tapped hole, this type of screw creates the mating thread within the base material, providing a secure and permanent connection. Lubrication is often recommended, particularly for harder materials, to reduce friction and heat buildup, which can compromise the screw’s mechanical properties.
