Key Features of Sealey Try Squares

Sealey try squares are engineered with hardened steel blades that provide the rigidity essential for accurate marking and checking operations. The blade edges are precisely ground to ensure true 90-degree angles, with this accuracy maintained through heat treatment processes that prevent warping or distortion during manufacture. Metric graduations are clearly marked along the blade length, allowing the try square to double as a measuring rule for layout work.

The stock components on Sealey try squares are manufactured from robust materials selected for dimensional stability and resistance to workshop knocks and drops. Many models feature brass or steel stock construction with precisely machined internal angles that guarantee perpendicularity between stock and blade. The stock faces are machined flat to ensure consistent contact with work pieces, eliminating the measurement errors that occur with warped or uneven reference surfaces.

Ergonomic considerations feature throughout the Sealey try square range, with stock designs that provide comfortable grip during extended marking sessions. The weight distribution is carefully balanced to allow single-handed operation whilst maintaining stability against the work piece. Blade and stock connections utilise secure fixing methods that prevent movement or loosening, ensuring the critical 90-degree relationship remains constant throughout the tool's service life.

Popular Sealey Try Squares

The Tooled-Up selection of Sealey try squares encompasses the sizes most commonly specified by professional tradespeople. The 150mm (6 inch) models represent the most versatile size for general carpentry and joinery applications, offering sufficient blade length for most marking tasks whilst remaining compact enough for comfortable tool belt carry. These smaller try squares excel in cabinet making, where working in confined spaces requires manoeuvrable measuring tools.

Mid-range 200mm and 250mm Sealey try squares bridge the gap between pocket-sized convenience and the reach required for larger fabrication work. These dimensions suit construction carpenters working with studwork, floor joists, and roofing components where checking squareness across wider timber sections is routine. The extended blade length also proves valuable when marking repetitive measurements, reducing the need to reposition the tool multiple times.

Larger 300mm (12 inch) Sealey try squares cater to structural carpentry, metalworking fabrication, and engineering applications where checking squareness across substantial components is essential. These robust models provide the blade length necessary for accurate layout on sheet materials, whilst the increased stock size offers enhanced stability against large work pieces. Heavy-duty construction ensures these larger try squares withstand the demanding conditions typical of fabrication shops and structural steelwork environments.

Safety and Compliance

Whilst try squares are inherently simple hand tools, proper use and maintenance ensures both personal safety and continued measurement accuracy. Sealey try squares should be inspected regularly for damage to blade edges, stock faces, or the critical blade-to-stock joint. Any distortion, burrs, or looseness compromises accuracy and the tool should be replaced rather than relied upon for precision work where measurement errors could affect structural integrity or component fit.

When using try squares for scribing or marking operations, ensure the work piece is securely held to prevent movement that could result in blade contact with hands or fingers. Sharp blade edges, whilst necessary for sliding beneath the scribe point, can cause cuts if handled carelessly. Store Sealey try squares in protective tool rolls or designated compartments that prevent contact with other tools, as impacts can damage the precisely machined surfaces essential for accurate measurement.

Regular cleaning removes sawdust, metal swarf, and debris that can interfere with the stock sitting flush against work pieces. A light application of rust-preventative oil on steel blades maintains corrosion resistance in damp workshop environments, though care should be taken to wipe excess oil before use to prevent marking timber or transferring residue to work surfaces.

Frequently Asked Questions

What sizes of Sealey try squares are most useful for carpentry work?

For general carpentry and joinery applications, a 150mm Sealey try square serves as the essential everyday tool, whilst a 300mm model provides the additional reach required for checking larger timber sections and sheet materials. Many professional carpenters carry both sizes to cover the full range of site requirements.

How accurate are Sealey try squares compared to premium engineer's squares?

Sealey try squares are manufactured to provide accuracy suitable for carpentry, joinery, and general metalworking applications. Whilst precision engineer's squares may offer tighter tolerances required for metrology or toolmaking, Sealey models deliver more than adequate accuracy for construction trades and workshop fabrication at significantly lower cost.

Can Sealey try squares be used for metalworking as well as woodworking?

Yes, Sealey try squares with steel blades and robust stock construction are entirely suitable for metalworking applications including layout marking, checking welded assemblies, and verifying perpendicular cuts. The hardened blade construction resists damage from contact with metal work pieces and fabrication benches.

How should I check if my Sealey try square is still accurate?

Test accuracy by marking a perpendicular line along a straight timber edge, then flipping the try square to the opposite face and aligning the stock with the same edge. If the blade aligns perfectly with the marked line, the try square maintains its 90-degree accuracy. Any visible gap indicates the tool requires replacement.

What's the difference between a try square and an engineer's square?

Try squares typically feature longer blades suited to carpentry and general workshop use, with stocks designed for comfortable handling during marking operations. Engineer's squares prioritise absolute precision with heavier, more rigid construction and shorter blades optimised for checking machined components and metalworking applications requiring tighter tolerances.
