Product Description

Core advantage

The Flanged hex weld nut integrates precise positioning, permanent anti-loosening, single-sided assembly, and adjustable strength. At the same time, it reduces the number of parts and labor hours, making it the preferred welding nut for thin sheet metal connections.

（1）Flange integration

Equipped with an enlarged flange surface, which evenly distributes the pressure and prevents the thin plate from collapsing. No need for additional washers.

（2）Three raised platforms, precise positioning

The bottom surface of the flange has three 120°-angled welding protrusions, which automatically align and prevent displacement.

（3）Permanent anti-loosening

After welding, the Flanged hex weld nut and the base material become an integral part. Under vibration and impact conditions, it will never loosen.

（4）Full range of strength grades (4.8 - 10.9 grades)

Low carbon steel (4.8/6.8 grades), medium carbon/alloy steel (8.8/10.9 grades), stainless steel (A2-70/A4-70) are available as options. Strength can be matched as per requirements, from household appliances to heavy truck chassis.

（5）A wide range of corrosion-resistant solutions are available:

Electro-galvanizing (48-120 hours salt spray), hot-dip galvanizing (500 hours+), Dacromet (1000 hours+), stainless steel in its natural color (304/316), etc. Suitable for harsh environments such as coastal areas, chemical plants, and outdoor locations.

（6）Single-sided assembly, no tools needed on the backside

The nuts have been welded onto the workpiece. Just tighten the bolts from one side, without the need to use a wrench to fix them on the backside. Especially suitable for narrow spaces such as closed boxes and interior cavities of the vehicle body.

（7）Suitable for large-scale automated production

Cold heading forming + threading, with good dimensional consistency; combined with automatic feeding vibration disc and resistance spot welding machine, the single-piece fastening cost is much lower than the "nut + washer" solution.
