Stewart Fastener J1224BHTZ No. 12 X 1.5 in Tek Screw

Product Description

The STEWART FASTENER J1224BHTZ is a No. 12 x 1.5 inch Tek screw designed for self-drilling fastening applications in metal-to-metal and metal-to-substrate assemblies. Tek screws eliminate the need for a pilot hole by combining a drill bit tip with a threaded shank, allowing faster installation in sheet metal, light structural steel, and framing components. This fastener is a standard choice for HVAC techs, sheet metal workers, electricians, and general trade contractors who need reliable, code-appropriate mechanical connections without pre-drilling.

The J1224BHTZ is suited for light commercial and residential trade work where a No. 12 diameter self-drilling screw is required. Common applications include HVAC ductwork assembly, electrical enclosure attachment, metal framing, and equipment panel fastening. The 1.5 inch length makes it appropriate for joining thin to medium gauge sheet metal where thread engagement and pullout strength are critical to the finished assembly.

Key Features

• Self-drilling tip eliminates need for a pilot hole, reducing installation time
• No. 12 diameter provides strong thread engagement in sheet metal applications
• 1.5 inch length suits thin to medium gauge metal-to-metal or metal-to-substrate joints
• Standard Tek screw form factor compatible with common hex-head driver bits

Compatibility

Designed as a standard No. 12 x 1.5 inch self-drilling Tek screw suitable for general sheet metal, HVAC ductwork, light structural steel, and metal framing fastening applications.

Installation Notes

Installation is performed with a power drill or impact driver fitted with the appropriate hex-head bit. Verify material gauge compatibility before driving to avoid screw over-penetration or stripped threads. Follow applicable building codes and manufacturer torque guidelines for the assembly being fastened. Always wear appropriate PPE when working with power-driven fasteners.
