14 x 1-1/2" Hex Washer Self-Drill Screw Zinc + Neoprene
Engineered for rapid and secure fastening of metal components, these 14 x 1-1/2" hex washer self-drilling screws eliminate the need for pre-drilling. The integrated drill point, threads, and hex washer head create a strong connection in a single step, while the bonded neoprene washer ensures a weather-tight seal.
- Self-Drilling (Tek) Point
- SAE J78 Compliant
- Zinc-Plated (ASTM B633)
- Integrated Neoprene Washer Seal
These self-drilling screws, commonly known as Tek screws, are manufactured from high-strength carbon steel to ensure durability and reliable performance. The drill-shaped point is specially hardened to penetrate metal decking, steel studs, and other structural components without a pilot hole. A zinc plating, applied in accordance with ASTM B633 standards, provides excellent corrosion resistance for long-term use in various environments. The entire fastener is designed and produced to meet SAE J78 performance specifications for dimensional accuracy and mechanical properties.
Ideal for construction, roofing, and MRO applications, these fasteners are the go-to choice for attaching metal panels, siding, and trim. The hex washer head offers a large bearing surface for increased holding power and allows for easy installation with standard nut setters. The bonded neoprene washer compresses during installation to form a durable, waterproof seal, making these screws perfect for exterior applications like securing roofing panels and HVAC ductwork where preventing leaks is critical. Bobco Metals is your source for bulk tek screws in Los Angeles.

Target Users
This product is essential for commercial roofers, HVAC technicians, steel framers, and general contractors who require a reliable and efficient fastener for metal-to-metal applications. Fabricators and maintenance crews also rely on these industrial-grade screws for assembly and repair work.
Finish Options
This screw features a durable zinc-plated finish (per ASTM B633) for effective corrosion resistance in typical atmospheric conditions. The integrated neoprene washer provides a secondary layer of protection by sealing the penetration point against moisture. For specialized environments, other coatings may be available via special order.
How to Measure
Self-drilling screws are specified by three main measurements: Gauge (diameter), Length, and Point Type. The gauge (e.g., #14) indicates the screw's diameter. The length is measured from the underside of the washer head to the tip of the drill point. The point type (e.g., #3, #4, #5) determines the thickness of the metal it can drill.
