DIN 126 specifies the dimensions of countersunk screws with slotted heads. These screws are commonly used in applications where a flush finish is desired, such as in woodworking or furniture assembly. The standard outlines the key measurements for these screws, including the diameter of the head, the angle of the countersink, and the overall length of the screw. By providing clear guidelines for these dimensions, DIN 126 helps to ensure uniformity and compatibility in the use of countersunk screws across various industries. This facilitates ease of use and reliability in their applications, making DIN 126 an important reference for manufacturers and users alike.
