Precision: The self-drilling point ensures fast penetration and reduces the chance of material splitting. Specifications: Length: 3/4" Diameter: #10 Material: Carbon Steel Finish: White Head Coating Drill Point Type: Self-Drilling Point #3 Quantity: 500 Screws per Pack Material Compatibility These screws are optimized for fastening into metal but can also be used in other materials: Primary Use: Metal-to-metal connections (steel, sheet metal, aluminum). Secondary Use: Can be used to fasten metal components to wood or fiberglass, though material thickness should be considered for optimal performance. Maximum Drilling Capacity: For a #3 Drill Point: The maximum recommended metal thickness is generally up to 12 gauge (approx. 0.11 - 0.15 inches or 2.8 - 3.8 mm) Installation Note: When installing, use a proper hex driver bit (5/16") with a power drill or impact driver. Apply steady pressure to engage the drill point and avoid over-torquing, which could strip the threads or damage the material or the painted finish. Avoid Over-tightening: Applying too much torque can strip the threads in the steel or break the screw head, compromising the holding power. The serration under the head helps to provide a secure grip, so excessive torque is not necessary. Use the Right Tool: A screw gun with adjustable torque or a clutch setting is highly recommended to achieve the correct and consistent tightness without overdriving the fastener. The recommended speed for #10 self-drilling screws is typically between 1200 and 1600 RPM.
