Styles and Functions of Tool Plate Holes — Classification and Applications by Structure

Counterbore Hole

Features: Cylindrical countersink with a flat bottom, designed to accommodate bolt heads or nuts.

Function: Distributes stress on fasteners and improves assembly flatness, commonly used in high-strength bolt connections.

Square Counterbore Hole

Characteristics: Square countersunk hole with a flat bottom, used for specialized fasteners (e.g., square-head bolts).

Function: Prevents fastener rotation, suitable for applications requiring high anti-loosening performance.

Countersink Hole

Characteristics: Conical countersink with a tapered bottom (typically 90° or 120°).

Function: Flushes the screw head with the workpiece surface, reducing stress concentration.

Through Hole

Characteristics: Penetrates the entire workpiece without a countersink structure.

Function: Used for bolt passage or fluid channels; simple to machine.

Blind Hole

Characteristics: Does not penetrate the workpiece; bottom is flat or tapered.

Function: Conceals fasteners or provides sealing capability.
