What Are Self-Tapping Screws? Types, Benefits and How to Choose

A self-tapping screw cuts or forms its own mating thread as it is driven, eliminating the need for pre-tapping. For manufacturers, that means faster assembly, fewer operations and lower cost per joint.

Thread-forming vs thread-cutting

• Thread-forming screws displace material to create a thread - ideal for plastics and softer metals, offering strong pull-out resistance
• Thread-cutting screws remove material with cutting edges - better for harder materials and thicker sections

Benefits that matter on the line

1. No pre-tapping - save an entire process step
2. Easy assembly - faster driving speeds with consistent torque
3. Strong joints - good pull-out and stripping resistance
4. Customization - head styles, thread forms and coatings tuned to your material

How to choose the right self-tapping screw

Consider these factors:

• Material to be fastened - plastic, sheet metal or wood each needs a different thread geometry
• Point type - sharp points for metal, drill points for thick sections, blunt points for plastics
• Head style - pan, flat, hex or wafer heads depending on tooling and appearance
• Corrosion environment - zinc plating indoors, stainless steel or Dacromet outdoors
