Unslotted Hex Washer Head Screw, #10-16 X 2-1/2", #3 Self-Drilling Point, Zinc w/Bonded Washer

The SP-HA1040 Unslotted Hex Washer Head Screw is a heavy-duty self-drilling fastener designed for secure metal-to-metal fastening with weather-resistant sealing. Featuring a #3 self-drilling point, this #10-16 x 2-1/2" screw eliminates the need for pre-drilling in many applications, while the bonded washer provides a tight seal against moisture. Finished in zinc for corrosion resistance, it’s built for strong holding power and dependable outdoor performance — because leaks and loose panels are never on the project list.
