Fastenic Group India Is leading manufacturer of Stainless Steel DIN 963 CSK Slotted Machine Screw in 304 & 316 Grade. DIN 963 is a standard specification for countersunk (CSK) Phillips machine screws. Here are the key characteristics of DIN 963 CSK (Countersunk) slotted machine screws:

• Head Style: CSK (Countersunk) screws have a flat head with a cone-shaped recess. The slotted head features a single straight slot, allowing for tightening or loosening with a standard flat-blade screwdriver.
• Thread: DIN 963 CSK slotted machine screws typically have metric threads. The thread size is specified by the standard, such as M3, M4, M5, etc. The pitch (distance between adjacent threads) is also defined.
• Length and Diameter: The standard specifies the range of screw lengths and diameters available for each thread size. You can find DIN 963 CSK slotted machine screws in various lengths to suit your specific application.
• Material: DIN 963 CSK slotted machine screws can be manufactured from different materials, including stainless steel (such as grades 304 and 316), carbon steel, or other alloys. The choice of material depends on factors like the intended application, environmental conditions, and desired properties like corrosion resistance.

It’s important to note that the slotted drive style, while traditional, may not offer the same convenience and ease of use as modern drive types like Phillips or Torx. Care must be taken to ensure proper engagement and alignment of the screwdriver during installation and removal.

By adhering to the DIN 963 standard, manufacturers ensure consistency and interchangeability of CSK slotted machine screws, making it easier for users to find compatible screws and achieve desired assembly results.
