Value Collection 1220ABW No. 12 Sheet Metal Screw Hex Washer

Product Description

The VALUE COLLECTION 1220ABW is a No. 12 sheet metal screw designed for fastening light-gauge metal components in HVAC, electrical, and general sheet metal fabrication applications. This screw features a hex washer head with a hex drive and a Type AB point, which combines a gimlet tip with coarse threads for fast, reliable engagement in thin metal without a pre-drilled pilot hole. It is manufactured from 1016/1024 grade steel with a zinc finish for corrosion resistance. At 1.25 inches length under head, it provides consistent seating depth across standard sheet metal gauges. Licensed tradespeople and sheet metal workers rely on this fastener in ductwork assembly, panel attachment, and enclosure fabrication.

This screw is suited for residential and commercial HVAC ductwork, electrical enclosures, metal stud framing, and general sheet metal assembly where a driven hex head provides superior torque resistance over slotted or Phillips alternatives. The hex washer head bears against the workpiece to distribute clamping load and resist pull-through. It is sold in minimum order quantities of 100 pieces per order and ships as a single-piece package unit, making it practical for job-site restocking. Installers working on duct systems, air handlers, rooftop units, and sheet metal panels will find this a standard-fit fastener for daily use.

Key Features

• No. 12 thread size for reliable engagement in standard sheet metal gauges
• Type AB point pierces light-gauge metal without requiring a pre-drilled hole
• Hex washer head distributes clamping load and resists pull-through
• Hex drive reduces cam-out under high-torque power tool use
• Zinc finish provides base-level corrosion resistance for indoor and protected outdoor installs
• Meets AISI 1016, ASME B18.6.3, ASME B18.6.4, and SAE J933 standards

Compatibility

Designed as a standard No. 12 Type AB hex washer head sheet metal screw suitable for light-gauge steel panels, HVAC ductwork flanges, electrical enclosures, and similar sheet metal assembly applications measured in the inch system.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, and electricians using a hex-drive bit or nut driver in a power drill or impact driver. Ensure the workpiece is clamped or supported before driving to prevent material distortion. Do not overdrive — hex washer head screws can strip the base material or deform the head flange if torque is not controlled. Refer to applicable SMACNA duct construction standards or NEC enclosure requirements for fastener spacing and seating specifications on regulated assemblies.
