Acorn TS834J Combination Tapping Screw 8x3/4 Jar Pack

Product Description

The ACORN TS834J is a No. 8 by 3/4 inch combination tapping screw sold in a jar pack configuration. Combination tapping screws are self-tapping fasteners designed to cut their own threads into sheet metal, light-gauge steel, and similar substrates without requiring a pre-tapped hole. They are commonly used in HVAC ductwork assembly, electrical enclosure installation, and general sheet metal fabrication. The jar pack format suits shop use and service vehicles where bulk access to fasteners is practical. Packaged weight is 0.48 pounds.

These screws are suited for light-duty sheet metal and panel fastening applications across residential and commercial HVAC, electrical, and plumbing trades. The No. 8 by 3/4 inch size is a standard dimension widely used for securing duct sections, junction box covers, equipment panels, and similar thin-gauge assemblies. The jar pack is appropriate for technicians who install or service sheet metal systems and need a reliable supply of fasteners on hand.
