The HTK10-0.75 is a single-unit, #10 x 3/4″ self-drilling screw, precision-engineered for metal-to-metal fastening without the need for pre-drilling. Constructed from durable carbon steel and coated with a zinc plating, this screw offers strong corrosion resistance for both indoor and outdoor environments.
Featuring a hex washer head with a 5/16″ hex drive, the screw provides a large bearing surface for secure seating, reducing the likelihood of material pull-through. The self-drilling tip efficiently cuts through light- to medium-gauge steel, saving installation time on site.
This individual fastener is ideal for HVAC systems, metal framing, ductwork, and electrical panel installations, offering clean drilling, secure fitment, and long-term durability.
