DIN 7997 - 1984 Cross recessed countersunk head wood screws  manufacturers in India

Metric DIN 7997 phillips flat countersunk head wood screws are the preferred fasteners used to attach wood to wood or hardware to wood as they have an  aggressive self tapping part thread with a sharp point which allows effective penetration and gripping in the wood hence forming strong joints. They have a head angle of approximately 90° and a flat countersunk head with a flat top surface used in applications where the head must be flush with the mating surface of the substrate. The Phillips (cross recessed) drive is cross-shape self-centering design that keeps it in place when you apply force from a drill while camming out if too much force/toque is applied.
