💡 What is a thread cutting screw with Type F point best used for in metal fabrication?

Handy explanation: It taps its own threads as it enters material, forming a secure hold without pre-threading.

• Thread cutting screws create mating threads in the wall of a hole, enabling strong fastenings in heavy metals.
• Type F point helps start cutting in heavy-gauge sheet metal and plastics, reducing thread skipping.
• Hex washer head distributes clamping force and resists pull-out in tight spaces.
• Zinc plating adds corrosion resistance for outdoor or humid environments.
