Stanley 1-45-686 Try Square, 300 mm — BOLTON SKU 57610.
About the Stanley 1-45-686 Try Square 300 mm
The Stanley 1-45-686 Try technical component is a try square with a 300 mm blade, listed under Stanley’s 1-45-686 catalogue reference rather than the E-465xx numbering used on some of the shorter sizes — worth noting when cross-checking an order, as the two numbering formats sit side by side in the same range. The tool works as any try square does: a blade held permanently at 90 degrees to a stock, registered against a datum edge either to scribe a square line or to test an existing angle for error. At 300 mm this is the longest of the commonly stocked sizes. The additional reach is the whole point of the size, and it is bought specifically for work too wide to be checked with a 200 mm or 250 mm blade. Blade length is measured outward from the working face of the stock.

Typical applications
A 300 mm blade covers full-width panels, door stiles and wide fabricated sections in a single setting, which is where the smaller squares run out of reach. It is used for marking out large carcass components, checking that tall assemblies stand square before they are fixed, and verifying the setup of larger machine tables and fences. Because the blade is long, it is also the size usually kept for final inspection checks rather than routine bench marking.
