Stewart Fastener J1016ACHZ Hex Washer Head Tapping Screw 100pk

Product Description

The STEWART FASTENER J1016ACHZ is a No. 10 x 1 inch Type A hex washer head tapping screw with a zinc finish, sold in a jar of 100. Type A tapping screws are designed to thread directly into pre-drilled or punched holes in thin sheet metal, making them a reliable fastening solution in HVAC ductwork, electrical enclosures, and light metal fabrication. The hex washer head provides a built-in bearing surface that distributes clamping force evenly and resists pull-through in thin-gauge materials. The zinc plating offers basic corrosion resistance for general indoor and light-duty applications.

These screws are widely used by HVAC technicians, sheet metal workers, and electricians for securing duct sections, metal panels, junction boxes, and equipment housings. The No. 10 diameter and 1 inch length suit standard light-gauge sheet metal assembly tasks encountered in residential and light commercial installations. The jar packaging keeps fasteners organized and accessible on the job site or in a service van.

Key Features

• Type A tapping screw thread form for use in thin sheet metal without a pre-tapped hole
• Hex washer head style provides a built-in washer surface for improved load distribution
• No. 10 x 1 inch size suits common light-gauge metal fastening applications
• Zinc plating for basic corrosion resistance in general indoor environments
• Jar of 100 units keeps fasteners organized and accessible during service calls

Compatibility

Designed as a standard Type A hex washer head tapping screw suitable for light-gauge sheet metal applications including HVAC ductwork, electrical enclosures, and metal panel assemblies.

Installation Notes

Installation is performed by HVAC technicians, sheet metal workers, and electricians using a hex-head driver or nut driver of the appropriate size. Pre-drill or punch a pilot hole sized to the screw shank diameter before driving into sheet metal to avoid material distortion. Do not overtighten, as overtorquing can strip the formed thread in thin-gauge material. Follow applicable codes including SMACNA ductwork standards and NEC guidelines for metal enclosure fastening.
