Key Features of Faithfull Engineers Squares

Faithfull engineers squares incorporate several design elements that enhance their utility and longevity. The hardened steel construction provides exceptional rigidity, preventing flexing during use that could compromise measurement accuracy. Ground faces on both the blade and stock create perfectly flat reference surfaces essential for precision work, whilst bevelled edges facilitate marking against the tool without the scriber point slipping underneath.

The blade and stock are securely joined through either precision riveting or welding, depending on the model, creating a permanent and stable 90-degree angle that won't shift with workshop knocks or temperature variations. Clear metric graduations are deeply etched into the blade, making measurements easy to read even in poorly lit workshop conditions. The satin chrome finish not only protects against corrosion but also reduces glare under bright workshop lighting.

Many Faithfull engineers squares feature rounded edges on the outer surfaces for comfortable handling during extended use, whilst maintaining sharp internal corners for accurate marking into tight spaces. The range includes both standard engineers squares and try squares, each designed for specific applications within metalworking and precision measurement disciplines.

Popular Faithfull Engineers Squares

The Faithfull engineers square collection at Tooled-Up encompasses sizes suited to diverse applications. The 50mm and 75mm models are particularly popular among model engineers, horologists, and those working on small precision components where compact size and manoeuvrability are essential. These smaller squares fit easily into toolboxes and are ideal for checking fine work on lathes and milling machines.

Mid-range sizes of 100mm and 150mm represent the workhorses of many engineering workshops, offering sufficient blade length for most general metalworking tasks whilst remaining portable and easy to handle. These dimensions strike an excellent balance between versatility and precision, making them suitable for everything from machine setup to component inspection.

Larger 200mm and 300mm engineers squares cater to fabrication work, structural steel projects, and applications requiring extended reach. These substantial tools provide the rigidity needed for marking long straight lines and checking larger assemblies, whilst their increased mass helps them sit stable on work surfaces during layout operations.

Safety and Compliance

Whilst engineers squares are relatively simple tools, proper handling ensures both personal safety and measurement accuracy. The hardened steel construction means these tools have sharp corners and edges that should be handled with care to avoid cuts or abrasions. When not in use, Faithfull engineers squares should be stored in protective cases or hung on tool boards to prevent damage to their precision ground faces.

Regular inspection of engineers squares is essential for maintaining measurement accuracy. Check that the blade and stock junction remains perfectly square using a known reference, and examine working surfaces for burrs, corrosion, or damage that might affect readings. Faithfull engineers squares manufactured to DIN 875 standards provide documented accuracy grades, giving users confidence in their measurements for quality-critical applications.

Keep measurement faces clean and free from swarf, oil, and debris that could prevent proper contact with workpieces. Store in dry conditions to prevent rust formation, and apply a light coating of protective oil if squares will not be used for extended periods. Never use engineers squares as hammers, pry bars, or for any purpose other than measurement and marking, as this will compromise their accuracy.

Frequently Asked Questions

What's the difference between Faithfull engineers squares and try squares?

Faithfull engineers squares feature all-metal construction with ground faces specifically designed for metalworking and precision engineering applications. Try squares typically have wooden stocks and are primarily intended for woodworking. Engineers squares offer superior accuracy and durability in workshop environments where metal components and cutting fluids are present.

How accurate are Faithfull engineers squares?

Faithfull engineers squares are manufactured to meet DIN 875 standards, which specify maximum permissible deviations from true squareness based on the tool's size. Typical accuracy ranges from 0.02mm to 0.05mm depending on the square's dimensions, making them suitable for professional engineering and quality control applications.

Can Faithfull engineers squares be used for woodworking?

Yes, Faithfull engineers squares work perfectly well for woodworking applications where precision is required. Their all-metal construction makes them more durable than traditional wooden-stocked try squares, and their accuracy exceeds what's typically needed for joinery. However, the steel construction makes them heavier and potentially more likely to mark softer woods if not handled carefully.

How should I maintain my Faithfull engineers square?

Keep working faces clean and free from debris, store in dry conditions, and apply a light protective oil coating if not using regularly. Avoid dropping or striking the square, as impacts can affect accuracy. Periodically verify squareness against a known reference, and never use the tool for purposes other than measurement and marking.

What size Faithfull engineers square should I choose?

Select size based on your typical work. For small precision components and model engineering, 50-75mm squares are ideal. General workshop use suits 100-150mm models, whilst fabrication and larger assemblies benefit from 200-300mm squares. Many professionals keep multiple sizes to hand for different applications.
