14 x ¾” Hex Washer Self-Drill Screw Zinc + Neoprene (42600)
Engineered for rapid and secure fastening of metal panels, our 14 x ¾” Hex Washer Self-Drill Screws eliminate the need for pre-drilling, saving time and labor. The integrated neoprene washer creates a watertight seal, protecting against moisture intrusion, while the zinc plating provides reliable corrosion resistance for exterior applications.
- Self-Drilling Fastener (Tek Screw)
- SAE J78 Compliant
- Zinc-Plated (ASTM B633)
- Integrated Neoprene Sealing Washer
These self-drilling screws, commonly known as Tek screws, are crafted from high-strength carbon steel to withstand demanding fastening tasks. The precision-formed drill point is designed to efficiently penetrate light to medium gauge metal without a pilot hole. A durable zinc plating, applied according to ASTM B633 specifications, offers a protective barrier against rust and corrosion. The bonded neoprene washer compresses during installation to form a durable, long-lasting seal that resists weathering and UV degradation, ensuring a secure and leak-proof connection.
Ideal for a wide range of construction and fabrication projects, these screws excel in applications requiring a secure, weatherproof fastening. They are the go-to choice for attaching metal roofing and siding panels to steel purlins or framing, assembling HVAC ductwork, and general metal-to-metal connections in MRO and industrial settings. The hex washer head provides a large bearing surface for excellent clamping force and is easily driven with standard nut setters, making them a versatile fastener for commercial construction hardware needs in the Los Angeles area.

Target Users
Primarily used by commercial roofers, steel erectors, HVAC technicians, and general contractors for projects requiring fast and reliable metal fastening.
Finish Options
This screw comes standard with a commercial-grade zinc plating (per ASTM B633) for effective corrosion resistance in most environments. The bonded neoprene washer provides a secondary layer of protection by sealing the fastening point. For projects requiring enhanced corrosion protection, alternative coatings may be available via special order.
How to Measure
Self-drilling screws are specified by their diameter (gauge number), length, and drill point number. Length is measured from the bottom of the washer head to the tip of the drill point. The drill point number (e.g., #3, #4, #5) indicates the thickness of the metal it can drill.
Example: 14 x 3/4" Hex Washer Head Self-Drilling Screw, #3 Point, Zinc + Neoprene
