Flat Head Countersunk Self Tapping Screws Zinc Plated Fine Thread For Wood Furniture and Cabinet Making
What Makes Self Tapping Screws Different
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.
Head Styles at a Glance
-
Flat Head – 82 degree countersunk. Sits flush with surface. Good for finished panels where you don't want screws sticking out.
-
Wafer Head – Low and wide. Clamps hard but doesn't stand tall. Popular for pocket holes and thin sheet metal.
-
Pan Head – Domed top, flat bottom. The everyday standard for most jobs.
-
Hex Head – Six sides. Use a wrench or socket. Good when you need extra torque.
-
Truss Head – Wide and low. Spreads pressure over a larger area without adding height.
-
Button Head – Low rounded dome. Looks clean. Works well where you want a lower head height.
Thread Types
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.
