Self Tapping Screws
Stainless Steel 304 Self Tapping Screws Phillips Pan Head Metric M3 M4 For Metal Sheet and Enclosure Assembly
What Are Self Tapping Screws
Screws that tap their own hole as you drive them in. No need to thread the hole beforehand. Just drill a pilot hole and drive.
When To Use Them
Any job where speed matters. Assembly lines. Field repairs. Quick fixes. If you are spending time tapping holes by hand these will speed you up.
Head Styles We Carry
Flat head: sinks into the wood or metal. Ends up flush with the surface. Good for finished work where you do not want screws sticking out.
Wafer head: is low and wide. Clamps down hard but does not stand up tall. Popular for pocket holes and thin sheet metal.
Pan head: is the everyday standard. Domed top flat bottom. Works for most jobs.
Drive Types
Phillips: is the cross shape. Everyone has a Phillips screwdriver. Works fine for most work.
Allen head: has a hex hole inside. Use a hex key. You can tighten these harder without stripping the head.
Thread Choices
Fine thread: has more threads per inch. Holds better in thin metal and harder plastics. Resists pulling out.
Coarse thread: bites faster. Better for softer materials like wood and regular plastic.
Material Options
Stainless steel: does not rust. Good outdoors or anywhere wet.
Brass: looks nice. Does not rust. Not magnetic. Good for electronics or anywhere appearance matters.
Galvanized: has a zinc coating. Decent rust protection for the price.
Black oxide: has a matte black look. Mostly for indoor use.
