Weld Nuts

Weld Nuts are designed to be permanently attached to a metal component by welding, providing a captive threaded point for assembly.

Design & Types

Weld-nut configurations include different body and projection arrangements depending on the parent material and access requirements.

Materials

The nut material and weldability must be compatible with the parent component and welding procedure.

Thread

Thread diameter, pitch and internal-thread tolerance are key procurement requirements.

Applications

Sheet-metal fabrication, equipment panels, enclosures, automotive-style fabrication and industrial assemblies.

Standards & Welding

The exact product standard and welding requirements should be confirmed against the drawing and welding procedure.

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.
