Reliable Hex with Washer Zinc-Plated Square Screw - #14 x 1 1/2-in - Self-Tapping - Self-Drilling - 100 Per Pack

Secure metal parts together using these hex head self-tapping screws. Their steel material is durable to last for years without wearing. Protected with a zinc coating, the screws resist rust and corrosion to make them suitable for outdoor use. These self-drilling metal screws create their own pilot hole through the material to eliminate pre-drilling. Attach a hex socket on the hex head with a washer to control the screw and prevent driver slippage during installation. These zinc-plated screws withstand friction to improve performance. They have a full self-tapping thread that provides a tight grip and secure hold to the metal. The screws measure 1 1/2 in L x #14. A box contains 100 screws to fit ventilation duct applications.
