ELCO DRIL-FLEX‚® 1/4-20" x 1-1/2" 4-Point Hex Washer Head Self Drill Screw - 100 Qty

Elco Dril-Flex 1/4-20 x 1-1/2 model EAF876 is a hex washer self-drilling screw designed for metal-to-metal fastening in commercial and industrial assemblies. The product functions as a self-drilling and self-tapping fastener for direct installation into steel members without separate drilling operations. The fastener is manufactured from alloy steel to provide controlled hardness and load-bearing capacity under installation torque. The Stalgard protective coating provides corrosion resistance suitable for interior and exterior service conditions. Installation is completed through an integrated drill point into pre-aligned metal substrates. The hex washer head provides consistent bearing surface and controlled torque transfer with standard hex drive tools. The fastener is compatible with steel framing, sheet metal, and light-gauge metal components. The product is intended for contractors, fabricators, and maintenance professionals. The bulk pack configuration supports jobsite supply and high-volume fastening requirements.

• Reduced Installation Steps



The self-drilling point supports direct metal-to-metal fastening without pre-drilling, which reduces tool changes and installation time.



• Consistent Clamp Load



The hex washer head distributes load across the bearing surface to support stable clamping of metal components.



• Corrosion-Resistant Finish



The Stalgard coating supports service life in environments where corrosion resistance is required for exposed fasteners.



• Controlled Driving Performance



The drive interface supports consistent torque application with standard hex drivers to reduce cam-out during installation.



• Jobsite Supply Efficiency



The bulk pack format supports inventory control for contractors and maintenance teams managing repetitive fastening tasks.
