Sealtite Steelbinder self-drilling screws are made for metal-to-metal fastening in general construction and HVAC work. The integral #3 drill point bores through steel up to 0.250" thick in one pass - no pilot hole required.

• Size: #10 x 1", 250 screws per box
• #3 self-drilling point, drills steel from light gauge up to 0.250" thick
• Indented hex washer head (1/4" socket) for fast bit engagement and secure clamp-down
• Plated carbon steel for interior dry-service use
• Common uses: HVAC ductwork, sheet metal joinery, light gauge framing, roof clip attachment

Tip: Drive with a 1/4" magnetic hex socket on a corded drill or impact driver. Apply firm even pressure during the drill phase so the point can clear chips; once the threads engage, let the screw self-tap. Bright-plated screws are not rated for treated lumber or exterior exposure - switch to a coated or stainless self-driller for those jobs.
