Conical-tipped slotted setscrews, defined in the DIN 553 standard published by the German Institute for Standardization (DIN), are grub screws with a slot at one end that allow easy tightening with a slotted screwdriver, and are typically made of steel or stainless steel. Set screws are typically part of an assembly and, when tightened, exert a clamping force against the surface of an interior object.
Similarly, the ISO 7434 standard published by the International Organization for Standardization (ISO) describes the specifications of products with metric dimensions and thread sizes from M 1,2 to M 12, including product class A (ISO 7434 Conical end slotted set screws). This standard also includes specifications relating to international standards, showing thread sizes from M 1,2 to M 12 in tabular form for nominal lengths from 2 mm to 60 mm, and providing an example for selection. If other specifications are required, it is recommended to comply with existing international standards such as ISO 261, ISO 888, ISO 898, ISO 965, ISO 3506, ISO 4759-1.
The requirements for conical-end slotted setscrews are included in the DIN 553 standard under the following headings:
The mechanical properties of tapered-end slotted setscrews are subject to ISO 898-5 for steel material, ISO 3506-3 for stainless steel material, and ISO 8839 for non-ferrous metal material. Tolerances are subject to the ISO 4759-1 standard.
