It takes only one sixth of a rotation to obtain the next side of the hexagon and grip is optimal. However, polygons with more than six sides do not give the requisite grip and polygons with fewer than six sides take more time to be given a complete rotation.

This made it virtually impossible to replace lost or damaged fixers, as they were all different. <a href="/wiki/Joseph_Whitworth" title="Joseph Whitworth">Joseph Whitworth</a> in 1841 proposed that a standard should be set, but it did not happen immediately. </p><p>In 1851 the <a href="/wiki/Great_Exhibition_of_the_Works_of_Industry_of_All_Nations" class="mw-redirect" title="Great Exhibition of the Works of Industry of All Nations">Great Exhibition of the Works of Industry of All Nations</a> was to be held in Hyde Park, London, England, and it was decided to build <a href="/wiki/The_Crystal_Palace" title="The Crystal Palace">the Crystal Palace</a> as part; this had to be done in 190 days, and at reasonable cost. Research into the remains of the destroyed building in 2024 revealed a major innovation that made this possible. The construction firm responsible, Fox Henderson, decided to use nuts and bolts, but to use standardised sizes, a revolutionary method at the time. This enabled the building to be completed in time. The use of interchangeable nuts and bolts was so successful that the Whitworth standard was widely adopted. A <a href="/wiki/British_standard" class="mw-redirect" title="British standard">British standard</a> was not formally adopted until 1905.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup> </p> <div class="mw-heading mw-heading2"><h2 id="Types">Types</h2></div> <p>There is a wide variety of nuts, from <a href="/wiki/Household_hardware" class="mw-redirect" title="Household hardware">household hardware</a> versions to specialized industry-specific designs that are <a href="/wiki/Engineering" title="Engineering">engineered</a> to meet various <a href="/wiki/Technical_standard" title="Technical standard">technical standards</a>.
