They make their own hole as you drive them in. No need to tap threads first. Just drill a pilot hole and go. This saves time on any assembly line.
More threads per inch. Holds better in thin metal and hard plastics. Harder to pull out.
Fewer threads per inch. Engages faster. Good for softer materials like wood and regular plastic.

YH Fastener started in 1998. We make self tapping screws, machine screws, shoulder screws, and custom fasteners. ISO 9001 and ISO 10012 certified. Every batch inspected. Factory direct. Ship to 60+ countries.
Self tapping screws create their own matching mating threads as they are driven in, eliminating the need for tapping threads beforehand and drastically saving assembly line production time.
Fine threads feature more threads per inch, making them ideal for thin sheet metals and hard plastics to resist pull-out. Coarse threads engage faster and are suitable for softer plastics and wood materials.
For standard outdoor or damp environments, 304 Stainless Steel provides excellent rust prevention. For harsh saltwater and marine applications, 316 Stainless Steel is recommended for maximum corrosion resistance.
We supply standard metric diameters from M2 to M6 with lengths from 6mm to 50mm, along with inch dimensions. Available property classes range from Grade 4.8 general use up to Grade 12.9 high tensile strength.
