Black Low Cylinder Flanged Round Through Thread Weld Nut

Core Features

Low Cylinder Profile – The nut features a reduced height relative to its diameter, providing a compact profile that minimizes protrusion from the mounting surface. The low configuration supports applications where clearance above the mounting surface is limited.

Integrated Flange – A circular flange is formed at the base of the cylindrical body, providing a load-bearing surface that distributes clamping force across the workpiece. The flange serves as a positive stop during installation and resists pull-through forces.

Through Threaded Bore – The internal thread extends through the full length of the nut body. The through-threaded configuration supports applications where full thread engagement is required or where bolt protrusion beyond the nut is specified.

Black Surface Treatment – The black finish provides a corrosion-resistant barrier layer with a uniform appearance, suitable for applications where surface appearance is a consideration.

Product Characteristics

The nut is manufactured with a low-profile cylindrical body and an integrated flange. The body height is dimensioned to provide a compact profile while maintaining sufficient thread engagement length. The flange diameter and thickness are dimensioned to provide load distribution and support weld formation.

The internal thread is produced with dimensions and tolerances following standard metric or unified thread profiles. Material composition is controlled to meet specified strength and weldability requirements. Low-carbon steel grades are typically specified for weld nuts to ensure weld quality and mechanical properties. The through-threaded configuration provides full thread engagement.

The black surface treatment is applied through a coating or conversion process, producing a consistent black surface with defined corrosion resistance properties. Alternative finishes are available based on application requirements.

Application Scenarios

Automotive Body Assembly – Used in vehicle body panels and structural components where permanent threaded attachment points are required and where the low profile minimizes protrusion from the panel surface.

Sheet Metal Fabrication – Applied where load-bearing threads are required in sheet metal that is too thin for tapping. The weld nut provides a permanent threaded insert through welding attachment, with the low profile supporting flush-mount applications.

Equipment and Enclosure Manufacturing – Used in equipment frames and enclosures where permanent threaded receptacles are required and where clearance above the mounting surface is limited.

Space-Constrained Assemblies – Employed in applications where component height must be minimized, as the low cylinder profile provides a compact fastening solution.

Customization Options

Specifications and configurations can be adjusted based on application requirements. Body height, flange diameter, thread size, and overall dimensions are customizable. Material grades include carbon steel for general applications and stainless steel for corrosion-resistant requirements. Surface treatments are selectable according to environmental exposure conditions.

Frequently Asked Questions

Q: What is the benefit of the low cylinder profile?
A: The low profile minimizes protrusion from the mounting surface, supporting applications where clearance above the panel or component is limited.

Q: Are these nuts removable after welding?
A: The weld nut is intended for permanent installation through resistance welding. Once welded, removal typically requires destructive methods such as grinding or cutting.

Q: What is the purpose of the flange on this weld nut?
A: The flange provides a load-bearing surface that distributes clamping force across the workpiece, serves as a positive stop during installation, and resists pull-through forces.

Q: What welding methods are compatible with this product?
A: Resistance welding is the primary method used. The flange provides a contact surface for electrode placement. Welding parameters should be set based on material grade, thickness, and equipment specifications.

Q: What is the function of the through-threaded bore?
A: The through-threaded bore extends through the full length of the nut body, providing full thread engagement for the mating fastener and supporting applications where bolt protrusion beyond the nut is required.

Installation Considerations

The nut should be positioned with the flange in full contact with the workpiece surface. Pre-weld surface preparation should include removal of oil, grease, and oxide layers from the nut contact area and workpiece surface to support weld consistency. For resistance welding, electrode force and welding current settings require calibration according to nut material grade, thickness, and equipment specifications. For plated or coated nuts, welding parameters should be adjusted to account for coating effects on electrical conductivity. The low cylinder profile provides a compact installation while maintaining thread engagement. Post-weld inspection should verify fusion quality through visual examination and torque testing when specified. The through-threaded bore should be inspected for thread damage or contamination before use.
