ISO1580 Slotted Pan Head Screws
ISO1580 is the international standard governing product grade A slotted pan head screws. It specifies the dimensional and technical requirements for metric threads ranging from M1.6 to M10, ensuring interchangeability for general-purpose fastening applications where a low-profile, rounded head with a slotted drive is required.

1. What is the standard scope and its relation to DIN85?
ISO1580 is the active international standard that supersedes the older German standard DIN 85. While similar, ISO 1580 serves as the updated global reference, incorporating revisions such as modified head dimensions for certain sizes and the removal of the former property class 8.8.
2. What materials and property classes apply?
The standard is material-neutral, with performance defined by the selected material's property class:
Carbon Steel: Commonly supplied as property class 4.8 for general-purpose use.
Stainless Steel: Typically A2-70 (AISI 304) or A4-80 (AISI 316), where the number indicates minimum tensile strength in MPa.
Other Materials: Brass or other alloys may be used, with mechanical properties as agreed between supplier and purchaser.
3. What are the typical applications and key usage notes?
These screws are used in general assembly across machinery, electronics, and consumer goods where a finished appearance is needed. The slotted drive requires a correctly sized flat-blade screwdriver to prevent cam-out and damage to the slot. Proper engagement length in the mating part is critical for achieving the screw's full clamping force.
