â–ŽUnderstanding Self-Tapping Countersunk Phillips 6×13 Screws: Dimensions and Applications 13/6 screw
â–ŽIntroduction
CSK Phillips 6×13 Self-tapping screws are integral fasteners used in a wide range of construction and manufacturing applications. Among these, the 6*13 self-tapping countersunk Phillips screw is particularly notable for its versatility and ease of installation. This article will explore the dimensions, features, and applications of this specific screw type, clarifying that the “6” refers to the screw number rather than its diameter. It is also known as 13/6, 6/13, 13*6, 6*13, 13×6
â–ŽWhat is a Self-Tapping Screw?
A self-tapping screw is designed to create its own hole as it is driven into materials, eliminating the need for pre-drilling. This feature makes installation quicker and more efficient, especially in various construction scenarios. The countersunk design allows the screw head to sit flush with the surface, providing a clean and professional finish.
â–ŽDimensions of the 13/6 Self-Tapping Countersunk Phillips Screw

The designation “6×13” refers to the screw number and length:
- Screw Number: 6 (indicating size)
- Length: 13 mm
- Diameter: 3.5 mm (for a #6 screw)
â–ŽDetailed Breakdown
- Screw Number (6):
- The “6” indicates the size of the screw, which is a common classification in the United States. It does not refer to the diameter but rather to a standardized sizing system.
- Length (13 mm):
- The length measurement refers to the distance from the underside of the head to the tip of the screw. A length of 13 mm is suitable for various applications, allowing for secure fastening in different materials.
- Diameter (3.5 mm):
- The diameter of a #6 screw is approximately 3.5 mm. This thickness provides an excellent balance between strength and ease of installation.
