304 small semi-circular head low square neck bolt M6*12 short square strength carriage bolt GB801
- Product description：The 304 stainless steel small pan head low square neck bolts, with their unique structural design and material advantages, have become the "invisible cornerstone" in numerous critical scenarios.
304 stainless steel as its core material, this type of bolt combines corrosion resistance and mechanical strength. The combined structure of the small pan head and low square neck not only avoids spatial interference caused by protruding heads, but also achieves precise anti-rotation through the square neck design. Its application scenarios cover multiple fields, ranging from high-end manufacturing to civil engineering projects.
In the field of building curtain wall engineering, the 304 small pan head low square neck bolt serves as a core component for connecting glass curtain walls and metal frames. Modern curtain walls pursue a lightweight and transparent visual effect, while also needing to resist stress impacts caused by wind, rain, and temperature changes. The small pan head design can be embedded in the grooves of curtain wall profiles, avoiding damage to the integrity of the appearance due to exposed bolt heads; the low square neck structure can be firmly clamped in the of the connector, preventing the bolt from rotating when the curtain wall deforms and ensuring the stability of glass panels. In addition, the 304 stainless steel material can resist corrosive factors such as outdoor humid air and acid rain. Even in coastal areas with high salt spray, it can ensure that the bolts do not rust for decades, effectively extending the service life of the curtain wall.
The medical device field has strict requirements for the precision and safety of connectors, and the 304 small pan head low square neck bolt demonstrates irreplaceable value here. In equipment such as surgical shadowless lamps and dental treatment chairs, bolts are required to connect adjustable mechanical arms and functional components. They must not only meet the needs of frequent rotation and adjustment, but also prevent metal parts from rusting and polluting the medical environment. The small pan head design can reduce hygiene dead corners on the equipment surface, facilitating daily disinfection and cleaning; the low square neck structure enables precise positioning, preventing equipment deviation caused by loose bolts during adjustment. At the same time, 304 stainless steel meets medical-grade material standards, does not contain harmful substances such as lead and nickel, and can be in direct contact with the medical environment, ensuring the safety of patients and medical staff.
In the food machinery manufacturing scenario, the material advantages and structural characteristics of this bolt are perfectly adapted to the industry's needs. Food processing equipment, such as beverage filling machines and bread production lines, needs to be in long-term contact with water, sugar, and acidic substances, and requires regular high-temperature cleaning and disinfection. The acid and alkali resistance of 304 stainless steel can prevent the bolts from rusting in the food processing environment and avoid food contamination by metal debris; the small pan head design can fit the equipment surface, reducing material residue, and the low square neck structure can ensure that the bolts remain stable in high-speed operating equipment, safeguarding production safety.
In addition, the 304 small pan head low square neck bolt is also widely used in the fields of marine engineering and smart home. In the construction of offshore platforms, its salt spray corrosion resistance allows it to be used for connecting marine instrumentation equipment and platform supports; in smart home appliances such as dishwashers and ovens, the small pan head design can improve the aesthetic appearance of the home appliances, and the low square neck structure can ensure the stability of component connections, meeting the needs of long-term use of home appliances.
