The cross recessed large flat head screw is a fastener with a cross
recessed hole design on the head and a flat or flat top.
1. Features
Cross recessed hole design: The head needs to be operated with a
wrench of the corresponding specification. It is not easy to slip
during installation and is suitable for scenes with limited space.
Flat head structure: The ultra-thin flat head design makes it
flush with the contact surface after installation, and the
appearance is neat and beautiful, especially suitable for occasions
with high requirements for surface flatness.
High-strength material: Common materials include 304/410 stainless
steel (corrosion-resistant) and carbon steel (strong economy). Some
products can reach 12.9 grade high strength, suitable for high-load
environments.
2. Standards and specifications
Standard: CM
Specifications : M2, M2.5, M3, M4, M5, M6
3. Application scenarios
Furniture assembly: Used to connect wooden or metal parts, taking
into account both stability and aesthetics, such as cabinets and
baby cribs.
Machinery manufacturing: Suitable for connecting parts of machine
tools, automobiles and other equipment, and the 12.9 grade
high-strength model can withstand extreme pressure.
Construction engineering: Used for the installation of outdoor
facilities such as steel structures and billboards, and the
stainless steel material has excellent weather resistance.
IV. Purchase suggestions
1. Material selection: 304/316 stainless steel (rust-proof) is
preferred for humid environments; carbon steel or galvanized
materials (cost-effective) are optional for conventional
environments.
2. Strength matching: 12.9 grade is suitable for heavy-duty
machinery; 8.8 grade meets general industrial needs.
3. Specification parameters: The thread length needs to be selected
according to the thickness of the connector (such as M5×20 means
diameter 5mm, length 20mm)
