BETA 016660130 – Flanged precision squares made from stainless steel ground and lapped — BOLTON SKU 59966.
About the Beta 016660130 Flanged Precision Square
Beta Tools item code 016660130 is the 1666A 300 flanged precision square, the 300 x 200 mm member of Beta’s 1666A range — one size up from the 200 x 130 mm 016660120. It is manufactured in stainless steel with ground and lapped working faces, and Beta’s 1666A datasheet references DIN 875, the standard that defines squareness accuracy for engineers’ squares. In a flanged square, the stock carries a widened flange that lets the tool stand upright unsupported on a plate or machine table and provides an extended seating face against a datum surface; on a 300 mm blade this stability matters, since a plain square of this size is awkward to hold steady single-handed. The stainless, lapped construction resists corrosion and preserves face quality through workshop handling.

Typical applications
The 300 mm blade reaches across larger fabrications — checking squareness of welded frames, machine sub-tables and fixture uprights where a 200 mm square runs out of length. It is also used standing on a surface plate as a vertical reference for height-gauge and indicator work on taller components.
