Stewart Fastener J1048BHTZ Hex Head Tek Screw 10-16 X 3 Zinc

Product Description

The STEWART FASTENER J1048BHTZ is a 10-16 x 3 inch hex head self-drilling tek screw with a zinc finish, designed for metal-to-metal and metal-to-substrate fastening applications. The self-drilling point eliminates the need for a pilot hole, allowing the screw to cut its own thread as it drives. The hex head provides a high-torque drive surface compatible with standard hex bit drivers and nut drivers. These screws are used in HVAC ductwork assembly, metal framing, roofing, and general sheet metal fabrication where a reliable mechanical fastener is required.

This screw is suited for light commercial and residential construction and mechanical trade work. Common applications include securing sheet metal panels, HVAC equipment enclosures, metal studs, and structural metal components. The zinc coating provides corrosion resistance appropriate for interior and protected exterior installations. Installers working in HVAC, metal fabrication, and general construction will find these screws compatible with standard hex driver tooling.

Key Features

• Self-drilling point eliminates pre-drilling for faster installation in sheet metal
• Hex head design accepts standard 5/16 inch hex bit or nut driver
• Zinc finish provides corrosion resistance for interior and protected applications
• 10-16 thread size suitable for metal-to-metal fastening
• 3 inch length accommodates thicker substrates and layered assemblies

Compatibility

Designed as a general-purpose self-drilling hex head tek screw suitable for sheet metal, HVAC ductwork, metal framing, and structural metal fastening applications.

Installation Notes

Installation should be performed by qualified tradespeople using a hex-head driver or nut driver set to appropriate torque to avoid stripping the head or overdriving into thin sheet metal. Do not exceed the material thickness rating for the drill point tip. When used in HVAC or mechanical enclosures, ensure fastener placement follows applicable equipment manufacturer guidelines and local mechanical codes.
