T-Square Drafting Tool - Precision Drawing Instrument for Architects & Engineers #108160 (License: Personal Use)

This black-and-white line illustration depicts a standard T-square, a fundamental drafting instrument consisting of a long horizontal blade and a perpendicular head that slides and locks along the edge of a drawing board. The head includes multiple screw holes for securing it at desired positions, while the blade often contains scale markings (not visible here) for measurements. Historically vital in architecture, engineering, and technical illustration before digital CAD tools became widespread.

Used on educational or professional drafting pages, museum archives, vintage tool collections, or historical design resources; matches user intent to identify, learn about, or source traditional drafting equipment.
