Mushroom-head Screw

 

Mushroom-head screws feature a mushroom-shaped head. They are non-slip, anti-loosening, and aesthetically pleasing, making them widely used in industries such as home appliances, electronics, and machinery.

Mushroom-head screws feature a hemispherical head, typically 30-50% larger in diameter than the threaded portion (standard head diameter is 6-20mm). This design not only looks aesthetically pleasing but also, more importantly, increases the contact area. Pressure distribution testing has shown that this reduces tightening pressure distribution by 40% (compared to flat-head screws), effectively preventing surface indentations on workpieces. Mushroom-head screws feature a slotted design for easy installation and removal, making them extremely convenient to use.

They are typically made of 304 or 316 stainless steel, offering excellent corrosion resistance. They can withstand neutral salt spray tests for over 48-96 hours, extending their lifespan by more than five times that of ordinary carbon steel screws. After cold heading, they achieve a hardness of HV 200-250 (approximately HRB 80-90), achieving both strength and toughness.

Mushroom head screws offer a certain degree of anti-slip and aesthetic appeal and are widely used in the following areas:

1. Furniture Manufacturing: They can be used to install a variety of furniture, such as beds, wardrobes, and desks.

2. Machinery Manufacturing: They are also widely used in machinery manufacturing, such as automobiles and aircraft, for fastening and connecting components.

3. Architectural Decoration: They are also used in architectural decoration, such as ceilings and wall coverings.

4. Electronics Industry: They are used to fasten components in home appliances, such as sockets, televisions, and refrigerators.
