Fasteners

Flange Nuts

Flange Nuts incorporate an integral flange beneath the nut to distribute clamping load over a larger bearing area.

Design

The integral flange acts as a built-in bearing surface and can reduce the need for a separate washer in applications designed for the nut.

Materials & Grades

Carbon steel, alloy steel and stainless steel options can be evaluated against applicable specifications.

Dimensions

Thread, flange diameter, flange thickness, nut height and width across flats are key procurement fields.

Applications

Machinery, equipment, automotive-style assemblies, fabrication and applications requiring an integral bearing surface.

Standards

Exact dimensional and material standards depend on the selected flange-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.
