The Malco BT153T Bit-Tip 10-24 x 3/4 self-tapping & self-drilling sheet metal screws are built to streamline metalwork from the first drill bite. Bit-Tip drills its own hole to the optimal size, delivering cleaner threads, stronger engagement, and a tighter fit with each fasten.

One-operation fastening means less fiddling with alignment, fewer tools, and faster installs. This screw is engineered for a wide range of industry applications—from HVAC ductwork and metal framing to structural and layered metal assemblies—making it a versatile choice for pros and serious DIYers alike.

Key benefits you’ll notice on the job:

• Self-drilling & self-tapping capabilities reduce the need for separate drill bits and taps, saving time on every project.
• Optimum hole size and uniform drill-point contours ensure consistent thread engagement and a tight, secure hold.
• One-step fastening eliminates misalignment issues, helping you complete installations faster and with less rework.
• Eliminates auxiliary fastening equipment like rivets, nuts and bolts, spot welds, or adhesives for cleaner, simpler assemblies.

The BT153T is crafted from strong, heat-treated steel and precision cold-forged to ensure uniform dimensions and drill-point precision. The 10-24 thread with a 3/4 inch length and a 5/16 inch hex washer head provides durable seating and reliable drive compatibility with standard screw guns.

Designed for real-world use, this screw can fasten:

• Metal framing and components
