Precision Rules Squares

Accurate Layout and Right-Angle Checking with Precision Rules and Engineers Squares

Precision rules and squares are the foundational layout and measurement tools in any engineering workshop, toolroom or fabrication environment — used to mark out, check squareness, verify flatness and establish reference measurements on workpieces before and during machining, assembly and fabrication.

A reliable engineers square and an accurate steel rule are among the most frequently used instruments on the bench, providing the reference against which all machined faces, cut edges and assembly joints are checked.

AIMS Industrial sells precision rules and squares from P&N, TTL, Sterling and Maxigear — measurement and precision tool brands supplying the engineering, toolroom and trade sectors across Australia.

The Precision Rules & Squares Range

Our broad product range covers engineers squares, combination squares, try squares and precision steel rules in metric and imperial formats for engineering, fabrication and trade use.

• P&N: P&N supplies precision measurement and layout tools as part of their broad engineering tooling range. P&N is an established Australian cutting tool and precision instrument brand with a history supplying the engineering trades.
• TTL: TTL supplies precision rules and squares for engineering and trade measurement applications. TTL’s precision instruments are designed for workshop and toolroom use where reliable squareness and dimensional measurement are required.
• Sterling: Sterling supplies precision rules and squares covering the measurement needs of engineering workshops and maintenance operations. Sterling is a recognised Australian industrial measurement and hand tool brand.
• Maxigear: Maxigear supplies precision rules and combination squares as part of their broader hand tool and measurement product range. Maxigear’s practical measurement tools suit trade and workshop use.

Choosing the Right Precision Rule or Square

Precision rule and square selection depends on the measurement task, the required accuracy and the tool format.

• Engineers Squares: Engineers squares provide a fixed 90-degree reference and are used to check and mark right angles on workpieces. They are ground to close tolerances and are the standard squareness check tool on the machining bench and at the assembly fixture.
• Combination Squares: Combination squares incorporate a sliding rule with a head that provides 90-degree and 45-degree reference angles. The sliding rule can be locked at any position for repetitive measurement and marking — making combination squares more versatile than a fixed engineers square for layout work.
• Steel Rules: Precision steel rules are used for direct length measurement and as a reference edge for scribing and marking. They are available in metric, imperial and dual-scale formats. Stiffer, thicker rules are easier to hold on edge for precise scribing.
