14 x 1-1/4" Hex Washer Self-Drill Screw Zinc + Neoprene
This industrial-grade 14 x 1-1/4" hex washer self-drill screw, also known as a Tek screw, is engineered to drill its own hole and tap its own threads in a single operation. The integrated neoprene washer creates a durable, weatherproof seal, making it ideal for securing roofing, siding, and panels to metal frames without pre-drilling.
- Self-Drilling Fastener (Tek Screw)
- SAE J78 Compliant
- Zinc-Plated (ASTM B633)
- Integrated Neoprene Sealing Washer
Manufactured from high-strength carbon steel, these self-drilling screws are heat-treated to ensure the drill point is harder than the substrate material. They are designed to meet SAE J78 performance standards for dimensional accuracy and strength. The zinc plating, applied according to ASTM B633 specifications, provides effective corrosion resistance for exterior and demanding MRO applications. The bonded neoprene washer is vulcanized to a steel washer, offering excellent resistance to UV, ozone, and weathering, ensuring a long-lasting, leak-proof seal against moisture and air.
These versatile fasteners are essential for commercial construction and industrial fabrication projects in the Los Angeles area. Their primary function is to attach metal panels, roofing, siding, and trim to steel or aluminum frames, eliminating the need for separate drilling and tapping operations. They are widely used in HVAC installations, metal building assembly, electrical enclosures, and general MRO tasks. The hex washer head provides a large bearing surface for secure clamping and allows for easy installation with standard nut drivers.

Target Users
These screws are indispensable for contractors, metal fabricators, roofers, and maintenance professionals who require a fast, reliable, and weather-resistant fastening solution for metal-to-metal applications.
Finish Options
This product features a durable zinc-plated finish compliant with ASTM B633 for excellent corrosion resistance. The integrated neoprene bonded washer provides a weatherproof seal. Other finishes or materials, such as ceramic-coated or stainless steel, may be available via special order for environments requiring enhanced corrosion protection.
How to Measure
Self-drilling screws are specified by their diameter (gauge size), length, and head type. The diameter is a number gauge (e.g., #14). The length is measured from the underside of the washer to the tip of the drill point. The drill point number (e.g., #3 point) indicates the maximum material thickness it can drill.
Example: #14 x 1-1/4" Hex Washer Head Self-Drill Screw, Zinc Plated.
