Square Nuts
Square Nuts have four flat sides and are used where a large bearing surface or anti-rotation feature is useful in the assembly design.
Design
The square profile provides a large bearing area and can assist with anti-rotation in suitable assemblies.
Materials & Grades
Applicable carbon steel, alloy steel and stainless steel options can be evaluated.
Dimensions
Thread, width across flats, thickness and corner geometry should be specified.
Applications
Fabrication, machinery, channels, tracks and assemblies designed around square-nut geometry.
Standards
The applicable dimensional and material standards depend on the specified square-nut design.
ASTM A194/A194M — High-Pressure / High-Temperature Nuts
Where the nut is specified for high-pressure or high-temperature service, ASTM A194/A194M is a key material specification covering carbon steel, alloy steel and martensitic/austenitic stainless steel nuts. ASTM currently lists A194/A194M-26 as active. Exact grade/class, size and service requirements must be matched to the governing specification; ASTM states that grade substitutions require purchaser permission.
Manufacturing & Sourcing
BCUBE operates through manufacturing and sourcing capabilities. Requirements can be evaluated from drawing, material, grade, standard, dimensions and quantity.
Certification & Inspection
EN 10204:3.1 material certificates and Indian or international third-party inspection can be supported where required by the order and agreed inspection scope.
Current & Previous Editions
Where a standard has multiple editions, BCUBE will identify the current edition and retain relevant previous editions for project-specific procurement searches. The client's approved drawing, specification and purchase order remain the controlling documents.
