Product Description:
Grade 10.9 Surface Finish Blue And White Zinc Pan Head Screw
Pan head design (dome and flat bottom) provides a larger pressure
bearing surface to prevent surface damage to the connecting parts.
It is a high-strength industrial fastener with a strength of 10.9
grade, suitable for heavy-duty connections;Its surface is blue
white zinc plated and can pass 48 hour salt spray testing,
combining rust prevention and aesthetics. The internal hexagonal
interface (requires installation with a hexagonal wrench) ensures
stable torque transmission and is suitable for operation in narrow
spaces.

Advantage:
Grade 10.9 Surface Finish Blue And White Zinc Pan Head Screw
The surface zinc layer isolates water vapor and oxygen, making it
suitable for humid environments such as bathroom furniture and
outdoor scaffolding. It has a lifespan 3-5 times longer than
ordinary steel screws.
Economical and practical
The price is only 1/3-1/2 of stainless steel screws, suitable for
scenarios with limited budget but requiring rust prevention.
The contact area under force is large
The diameter of the disc head is larger (compared to round/flat
heads), which disperses pressure and prevents the screw head from
getting stuck in soft materials such as plastic and wood
fiberboard.
Applications:
Home appliance production
The assembly of televisions, refrigerators, ovens, coffee makers,
and water dispensers all require the fastening of pan head screws.
For the installation of large-sized televisions, a large number of
pan head screws are needed to connect them.
Automobile production
The fastening of engine components and the connection of interior
parts require pan head screws.
