Timco PZ2 4.0 x 30mm Yellow Zinc Double Countersunk Woodcrews (200 Box)

These 4.0 x 30mm multi-purpose screws are engineered for use in hardwood, chipboard, MDF, plastic, and thin sheet metal. Featuring a double countersunk head to reduce head shear and ensure smooth countersinking, they also include patented lubrication for easier insertion and corrosion resistance. The deep single thread provides strong pull-out resistance, while the surface hardening prevents torque shearing.
