Stewart Fastener J0812BHTZ Hex Washer Head Tek Screw 8-18

Product Description

The STEWART FASTENER J0812BHTZ is a self-drilling tek screw designed for fast, reliable fastening in metal-to-metal and metal-to-light-gauge-steel applications. Sized 8-18 x 0.75 inches, this hex washer head screw features a built-in drill point that eliminates the need for a pilot hole, reducing labor time on the job. The steel construction with zinc plating provides corrosion resistance suitable for general trade use. Each jar contains 100 screws and is sold per each jar. HVAC, sheet metal, electrical, and general construction tradespeople rely on this fastener type for ductwork, panel attachment, and structural sheet metal assembly.

This screw is suited for light-gauge sheet metal applications commonly encountered in HVAC duct fabrication, equipment enclosure assembly, and electrical panel work. The hex washer head allows for consistent torque delivery with a standard hex driver or nut driver, making it a practical choice for field and shop installations alike. The 100-count jar keeps screws organized and accessible on the job site.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, and electricians using a standard hex driver or nut driver. No pilot hole is required due to the self-drilling point. Apply consistent, controlled torque to avoid stripping the fastener or deforming thin sheet metal. Follow applicable local codes and manufacturer guidelines for fastener spacing and load requirements.
