At Ananka Fasteners Pvt Ltd, we manufacture fasteners to the dimensional requirements of DIN 97. DIN 97 covers slotted countersunk (flat) head wood screws. The 90-degree flat countersunk head seats flush with the material surface. Threads follow the wood screw (AB) form to DIN 7998 with a gimlet point for driving into timber and soft materials.
