Stewart Fastener J1216ACPZ Pan Head Type a Tapping Screws 12x1 100pk

Product Description

The STEWART FASTENER J1216ACPZ is a jar of 100 No. 12 x 1 inch pan head, combination-drive, Type A tapping screws with a zinc plated finish. Type A tapping screws are designed for threading into pre-punched or pre-drilled holes in sheet metal, light-gauge steel, and similar materials without requiring a pre-tapped thread. The pan head profile keeps a low, wide bearing surface against the workpiece, and the combination drive accepts both slotted and Phillips drivers. Zinc plating provides basic corrosion resistance for indoor and sheltered applications. These fasteners are a standard consumable in HVAC, sheet metal, electrical, and general mechanical trade work.

These screws are suited for light sheet metal fabrication and assembly tasks common in HVAC ductwork, electrical enclosure work, and plumbing access panel installation. The No. 12 diameter and 1 inch length make them appropriate for joining thin-gauge sheet metal panels and brackets. They are sold in a jar of 100, which is a practical job-site or shop quantity for technicians who use this size regularly.

Key Features

• Type A thread form cuts its own mating thread in sheet metal and thin materials
• Pan head profile provides a wide, flat bearing surface with low overall height
• Combination drive accepts slotted or Phillips No. 2 drivers and bits
• Zinc plated finish for basic corrosion resistance in sheltered environments
• No. 12 x 1 inch size is a common standard for light sheet metal assembly
• Jar of 100 for convenient job-site storage and dispensing

Compatibility

Designed for use in pre-punched or pre-drilled holes in light-gauge sheet metal and similar thin substrate materials typical in HVAC, electrical, and sheet metal trade applications.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, and electricians using a standard No. 2 Phillips or slotted bit driver. Always verify hole diameter matches the recommended pilot size for No. 12 Type A screws to prevent stripping or cracking of the base material. Do not overtorque — pan head tapping screws in sheet metal can strip the formed thread if driven past seating. Ensure mating material thickness is appropriate for a 1 inch fastener to achieve adequate thread engagement.
