Stainless Steel Carbon Steel Hex Flange Nut

This series of flange anti-slip nuts (also known as flange locking nuts or flange locking screws) is an innovative type of fastener that integrates a hexagonal nut, a flange gasket, and an anti-slip and anti-loosening structure. The nut body is integrally formed with the flange disc, and the end face of the flange disc is equipped with precise embossed anti-slip teeth. When tightened, the tooth surface embeds into the contact surface of the workpiece, significantly increasing the mechanical friction force. No additional flat washers or spring washers are required; a single nut can achieve the triple effects of "fastening + anti-loosening + anti-slip".

The product offers four mainstream versions: stainless steel color, white zinc plating, colored zinc plating, and Dacromet treatment. It covers various industrial scenarios as well as complex working conditions such as outdoor high corrosion and high-frequency vibration. It is an efficient upgrade solution to replace the traditional "nut + gasket" combination and is widely applicable to various threaded connection scenarios.

Three-in-one structure, installation efficiency doubles directly

Equipped with integrated flange and anti-slip teeth, eliminating the need for additional installation of flat washers and spring washers, the installation can be completed with a single nut, significantly reducing assembly steps. Especially suitable for batch production and high-altitude operation scenarios, the installation efficiency is increased by more than 50% compared to traditional solutions.

Double anti-slip and anti-loosening, ensuring maximum tightening reliability

The flange increases the contact area between the nut and the workpiece, dispersing pressure and avoiding damage to the workpiece surface; the end face anti-slip teeth embed in the contact surface when tightened, forming a mechanical bite, effectively resisting loosening caused by vibration and impact, with a loosening effect far exceeding the combination of ordinary nuts and washers.

Multiple versions for all scenarios, precise selection as needed

304 stainless steel model: Excellent corrosion and rust prevention performance, does not rust even in humid, outdoor, and coastal environments for long-term use;

Galvanized (white zinc / colored zinc) model: A cost-effective choice, with basic rust prevention ability, suitable for most conventional industrial scenarios;

Dacromet model: Super strong corrosion resistance, suitable for chemical, marine, salt spray and other strong corrosive working conditions, with a service life far exceeding that of ordinary galvanized parts.

Integrated molding process, uniform force and no failure

The nut and flange are forged as a whole, without welding or splicing, with uniform force and no fracture; the thread adopts precise rolling processing, with strict tolerance control, perfectly compatible with standard metric bolts, and tightening smoothly without slippage or jamming.

Wide temperature range and durability, suitable for complex working conditions

High-quality carbon steel / stainless steel material combined with professional surface treatment, can maintain stable performance in a -40℃~150℃ wide temperature range, resistant to vibration and aging, long-term use is not prone to deformation or failure, significantly reducing equipment maintenance costs.

• Mechanical Assembly: Used to fasten various mechanical components together, such as gears, shafts, and housings in machines and equipment.
