Malco bt141-100 Hex Washer Head Self-drilling Screws 10 X 0.5 Inches 100 Pack

Product Description

The Malco bt141-100 is a 100-pack of hex washer head self-drilling screws designed for metal-to-metal fastening in HVAC, sheet metal, and light commercial construction applications. These screws are built for trade professionals who need a reliable, high-volume fastener that drives fast and holds tight. Each screw features a drill point size 2 tip, which means it can pierce light gauge steel without a pilot hole, saving time on the job. The hex washer head style provides a broad bearing surface that distributes load and resists pull-through, making it a preferred choice for ductwork assembly, equipment panels, and sheet metal enclosures. The 10 x 0.5 inches sizing is one of the most common specifications in HVAC sheet metal work, compatible with standard hex driver bits and magnetic nut drivers. Malco screws are heat treated for added hardness and shear strength, which is critical when fastening through multiple layers of galvanized steel or aluminum. The 16 TPI thread count is engineered for positive thread engagement in thin gauge metal without stripping or cam-out. Steel construction ensures durability under the mechanical stress and vibration found in HVAC systems. HVAC installers, sheet metal workers, and mechanical contractors rely on this type of fastener for duct connections, access panels, and equipment mounting. Buying in a 100-pack reduces downtime on large jobs and keeps the toolbox stocked for repeat tasks. These screws are compatible with standard 5/16 inch hex driver bits, which are common in cordless drills and impact drivers used in the field. Whether you are assembling spiral duct, securing duct board, or fastening sheet metal components, the Malco bt141-100 delivers consistent performance across a wide range of light commercial and residential HVAC applications.

• Drill point size 2 tip eliminates the need for pre-drilling through light gauge steel
• Heat treated steel construction for increased hardness, shear strength, and long service life
• 100-pack quantity reduces restocking frequency on high-volume sheet metal and HVAC jobs
