The Moore & Wright 400R Series Traditional Engineers Squares are precision inspection tools designed for checking squareness, alignment and right angles in engineering, manufacturing, machining and workshop environments. Manufactured to BS939 Grade B standards, these engineers squares provide a dependable solution for checking components, workpieces and machined surfaces during precision inspection and quality control applications.
Featuring precision-ground blades and stocks, the Moore & Wright 400R Series is designed to provide accurate reference surfaces for checking 90-degree angles. The hardened and tempered blades offer durability for regular workshop use, whilst the blind-riveted construction provides a robust connection between the blade and stock. These traditional engineers squares are particularly suitable for toolmaking, machine setup, fabrication and dimensional inspection.
Available in five sizes ranging from 75mm (3 inches) to 300mm (12 inches), the Moore & Wright Traditional Engineers Squares offer a practical choice for engineers, machinists and inspection professionals requiring reliable squareness checking across a variety of component sizes. Their precision-ground construction and established manufacturing standard make them suitable for general engineering and quality control applications.
