Each plaquette action has the product of four bond variables; the partition function is the integral over the Boltzmann factor with a product over bonds of \u0000\t\t\t\t&lt;span&gt;&lt;math&gt;&lt;mi&gt;G&lt;/mi&gt;&lt;/math&gt;&lt;/span&gt; Haar measures. Formally, in the continuum, ultraviolet (UV) limit &lt;em&gt;a &amp;&lt;/em&gt;drarr; 0, the action gives the YM classical continuum action. For free and periodic boundary conditions (b.c.), and using scaled fields, defined with an &lt;em&gt;a-&lt;/em&gt;dependent noncanonical scaling, we show thermodynamic and UV stable (TUV) stability bounds for a scaled partition function, with constants independent of &lt;em&gt;L, a&lt;/em&gt; and &lt;em&gt;g.&lt;/em&gt; Passing to scaled fields does not alter the model energy-momentum spectrum and can be interpreted as an a priori field strength renormalization, making the action more regular. With scaled fields, we can isolate the UV singularity of the finite lattice physical, unscaled free energy &lt;em&gt;f&lt;/em&gt;Λ(&lt;em&gt;a&lt;/em&gt;) = [ln ZΛ ]/Λ&lt;em&gt;&lt;sub&gt;s&lt;/sub&gt;&lt;/em&gt;, where Λ&lt;sub&gt;s&lt;/sub&gt; = &lt;em&gt;L&lt;sup&gt;d&lt;/sup&gt;&lt;/em&gt; is the total number of lattice sites. With this, we show the existence of, at least, the subsequential thermodynamic (Λ &amp;nearr; &lt;em&gt;dℤ&lt;sup&gt;d&lt;/sup&gt;&lt;/em&gt;) and UV limits of a scaled free energy. To obtain the TUV bounds, the Weyl integration formula is used in the gauge integral and the random matrix probability distributions of the CUE and GUE appear naturally. Using periodic b.c. and the multireflection method, the generating function of &lt;em&gt;r&lt;/em&gt; scaled plaquette field correlations is bounded uniformly in &lt;em&gt;L, a, g&lt;/em&gt; and the location/orientation of the &lt;em&gt;r&lt;/em&gt; plaquette fields.
