4.0 x 35mm Countersunk Zinc Yellow Passivated Wood Screw

Summary

A 4.0 x 35mm countersunk wood screw with a zinc yellow passivated (ZYP) finish, suitable for general timber fixing applications in construction, joinery, and carpentry.

• Pozi or cross-head drive recess compatible with standard driver bits widely available on site.
