Newly developed petal washer

10/19/2010

Many of our customers do not want screws to be seen on the surface.
"If screw top has come out, children may knock up against it"
"Though the house is airtight, screw acted as a heat bridge resulting in condensation…"
"Child will rotate the screw if it is seen"
"Want to give good appearance by hiding the screw"
"Short circuit occurred at the screw head"
How about trying out "Petal Washer"?
It is made by adding "Protection", "Insulation" and "Design" to normal screw.

Method of use if as follows.

Mount it on the screw and

tighten with a driver.

Petal will close after you remove the driver. You are done!
