SpecialInsert Flower Nut, M6 Zinc Plated

Description

The SpecialInsert flower nut TC-F is a deformable jack nut insert designed for thin panels and blind sections where the back side of the material cannot be reached. Made from zinc-plated mild steel, the insert threads M6 and opens into a wide flower-shaped foot as the setting tool draws the mandrel through the body, spreading load across the panel instead of relying on a small crimp point. That broad bearing surface is the main reason fabricators reach for a flower nut instead of a standard cylindrical rivet nut whenever the base material is soft, thin, or already close to its pull-through limit.

Where the SpecialInsert Flower Nut Fits

• Boxed sections, tubes, and closed profiles with no rear access for a standard nut
• Thin sheet metal panels prone to pull-through with a standard rivet nut
• General manufacturing and metal fabrication assemblies needing a removable M6 point
• Sign, display, and transportation builds where panel thickness varies across the run

SpecialInsert Flower Nut Specifications

• Thread: M6
• Material: zinc-plated mild steel
• Style: flower/jack nut, wide-foot deformation for broad backside bearing
• Best suited to thin or blind sections where a cylindrical rivet nut has too little bearing area

Drill the panel to the specified hole diameter, insert the flower nut, and set it with a compatible jack nut tool. As the mandrel draws through the body, the far end opens into a broad foot that spreads clamp load across the panel instead of concentrating it at one small point, which is what lets this style hold in thinner material than a standard cylindrical rivet nut. The finished M6 thread accepts a bolt or stud with no welding and no access to the reverse face, and because the foot spreads across a wider area than a simple crimp, the joint resists pull-through even when the surrounding panel flexes under load.
