METRIC SLOTTED SET SCREW DIMENSIONS

Dimensions of metric slotted set screw with flat point are shown in the following chart according to DIN EN ISO 4766-1:2011 standard.

DIN EN ISO 4766 specifies the characteristics of slotted set screws with flat point and thread sizes from M1.2 up to and including M12.

Some important notes from DIN EN ISO 4766 standard:

- Thread tolerance class: 6g

- Hardness Classes: Steel - 14H, 22H; Stainless Steel - A1-12H

- Finish: For steel screws, electroplating per ISO 4042 and zinc flake coatings per ISO 10683. For stainless steel screws, passivation per ISO 16048.

- Designation: Set screw ISO 4766 - M5 x 12 - 22H (A slotted set screw with flat point, thread size d=M5, nominal length l=12 mm, steel with hardness class 22H)
