Each block in this new pair is individually serialized (400604A and 400604B) and ships with a certification traceable to national standards, confirming all six faces are square and parallel within the stated 0.0001 in tolerance. The hardened steel construction and precision-ground surfaces make these blocks suitable for use as a reference standard, sine plate support, CMM fixturing aid, surface plate layout work, and general workholding on milling machines and magnetic chucks. The single-hole ('H1') configuration distinguishes this model from multi-hole variants, providing a centered clearance bore that accommodates a clamping bolt without compromising the reference faces. This pair is stored and shipped in a fitted wooden case to protect the ground surfaces, and both blocks carry Suburban Tool's 'Tools to Grow With' certified quality mark.\u003c\/p\u003e\n\u003ch3
