[Technical Data] Sheet Metal Basics Course, Session 13: Dish Forming Process, Weld Nuts, and Others

Introducing nuts used for welding to plates and methods for welding studs to plates!

For joining sheet metal parts, tapping is often used, but when using screws, a countersink may be made on the mounting side of the part to ensure that the screw head does not protrude from the surface. In addition to tapping, there are methods such as welding nuts and bolts, as well as press-fitting nuts and bolts. This document introduces these joining methods. Please feel free to download and take a look. [Contents] ■ Countersinking ■ Weld nuts ■ Stud welding ■ Fasteners (press-fit bolts and press-fit nuts) *For more details, please refer to the PDF document or feel free to contact us.

Selection of welding nuts for the reduction of work hours.

[Knowledge for Selecting Other Accessories and Parts] Easy positioning with a pilot!

【Before】 ■Hex Nut For thin plates where tapping cannot be done, hex nuts can be used for various screw fastening applications by welding them. However, when using standard hex nuts, it can sometimes be difficult to position them correctly during welding. ↓ 【After】 ■Hex Weld Nut In the case of hex weld nuts with a pilot, drilling a pilot hole at the welding point makes positioning easier, thereby improving work efficiency. *For more details, please refer to the catalog or feel free to contact us.

Welding Fastener "Weld Nut (Welding Nut)"

Welding Fastener "Weld Nut (Welding Nut)"

Welding fasteners are an excellent solution for creating ultra-strong and permanent connections between steel and fasteners.

Weld nuts are designed to weld the nut to a metal base material, achieving high-strength nut fixation in limited spaces. Depending on the application, they may also be used as a substitute for self-clinching fasteners. Weld nuts form a very strong bond. However, because a welding process is required, they are not subjected to plating treatment to prevent corrosion. After the welding process is complete, painting or plating is applied to protect the welded nut from corrosion.
