Need a fast way to secure light-gauge metal without drilling a pilot hole first? That’s where zip screws earn their spot in the toolbox. These sharp-point fasteners are built to pierce thin sheet metal, pull pieces together, and stay seated on a 1/4" hex driver while you work.
At Supply Maverick, you’ll find #8 x 1/2" painted zip screws made for metal roofing trim, siding laps, flashing, ductwork, and other light sheet metal work. Choose painted stainless steel when corrosion resistance matters most, or go with painted zinc-coated steel when you need a budget-friendly fastener for less demanding jobs. Most orders placed before 12 noon EST ship the same day, so you’re not stuck waiting on a small part that can hold up the whole project.
Both types of zip screws we offer feature a 1/4" hex hi-hex, deep head design that maximizes grip and helps prevent the driver from slipping during installation.
| Product | Best Fit | Material | Size | Colors | Package Quantities |
| Zip Screws - #8 x 1/2" Painted Stainless Steel | Exterior trim, flashing, siding laps, and moisture-prone sheet metal work | 410 stainless steel | #8 x 1/2" | White, black, musket brown, dark bronze | 100 or 1000 |
| Zip Screws - #8 x 1/2" Painted Zinc-Coated Steel | Interior projects, sheltered work, and cost-sensitive fastening | Zinc-coated steel | #8 x 1/2" | White, black, musket brown, dark bronze | 100 or 1000 |
Paint finishes are matched to standard roofing industry colorways. Because names are generic and different panel manufacturers use proprietary paint blends, please verify your trim color against our options before ordering.
Zip screws are self-piercing sheet metal screws with a sharp needlepoint tip and threads that bite quickly into thin metal. With the right driver pressure, the point punctures the metal, the threads engage, and the fastener seats in one motion.
Contractors rely on that speed for trim details, siding overlaps, and HVAC ductwork. They’re also accessible for homeowners tackling small metal siding repairs or weekend trim projects.
A zip screw is different from a self-drilling screw. Self-drilling (Tek) screws have a drill-bit-style tip for thicker steel. Zip screws use a piercing point, ideal for thin sheet metal, where a drill point would strip the material.
Zip screws join light-gauge metal quickly and cleanly. On metal roofs, that usually means trim and accessory work rather than fastening the main panels to the roof deck.
| Application | How Zip Screws Help | Installation Note |
| Metal roofing trim | They fasten ridge cap edges, flashing, and trim overlaps without pilot holes. | Use the right color finish where the head will be visible. |
| Metal siding | They pull lap joints and accessory pieces together with a clean, low-profile finish. | Keep the screw straight so the painted head seats flat. |
| HVAC ductwork | They pierce thin duct metal quickly in tight spaces. | Avoid overdriving, especially near duct edges. |
| Sheet metal repairs | They’re useful for light patching, small brackets, and panel overlaps. | Check the metal thickness before choosing a self-piercing screw. |
| Gutters and light metal accessories | They can secure light metal pieces where a washered roofing screw is unnecessary. | Match the material to the exposure level. |
For structural steel or main roof panels, choose a heavy-duty fastener. Main roof panels require washered roofing screws to create a permanent, weather-resistant seal.
Material choice comes down to exposure, budget, and how long you expect the connection to stay in service. Exterior jobs require high corrosion resistance, especially around roof trim, siding edges, and damp areas. Sheltered interior work can use standard protection.
| Choice | Use It For | Main Benefit | Watch For |
| Painted 410 stainless steel zip screws | Exterior trim, flashing, siding, and wet or humid environments | Better corrosion resistance over time | Higher upfront cost |
| Painted zinc-coated steel zip screws | Interior sheet metal, sheltered trim, and light exterior work with lower exposure | Good value for routine fastening | Less corrosion resistance than stainless steel |
Use zinc-coated for interior duct runs, protected shop projects, or budget-sensitive indoor repairs.
For roofing trim, siding laps, and HVAC ducts, #8 x 1/2" is the standard size. This length provides maximum thread engagement in thin sheet metal without leaving a long, exposed screw point on the back side.
Excessively long screws create clearance problems, snag insulation, and pose a puncture hazard. If you’re fastening thicker assemblies, layered materials, or different substrates, make sure you choose the right fastener type.
Zip screws are made exclusively for light-gauge sheet metal. As a general working rule, they’re most useful on thin metal components, including trim, flashing, siding accessory pieces, and ductwork.
A self-drilling screw is a better fit for cutting through thick steel framing, purlins, and structural metal connections. For wood substrates under roofing panels, use metal-to-wood roofing screws with sealing washers. Matching the fastener to the substrate saves time, protects the panel finish, and minimizes the risk of a weak connection.
Good zip screw installation is mostly about control.
The deep hi-hex heads help the fasteners stay on the bit, which is an advantage when you’re moving down a long trim run or working overhead.
A few small mistakes can create bigger problems later.

Zip screws fasten thin sheet metal without predrilling. In metal roofing and siding, they’re commonly used for trim, flashing, lap joints, and light accessory pieces. HVAC installers also use them to assemble sheet metal ductwork.
Yes, but only for trim and flashing connections where light-gauge metal overlaps. For fastening main metal roof panels to wood or steel framing, always choose a washered roofing screw to ensure a watertight seal.
The standard size is #8 x 1/2". It provides optimal thread bite in thin metal while limiting how far the sharp point protrudes on the back side.
No, they’re self-piercing. Zip screws use a needlepoint to puncture thin metal. Self-drilling (Tek) screws have a built-in drill-bit tip designed to cut through thick steel.
Yes, they’re ideal for metal siding laps, trim pieces, and light-gauge accessory connections. Match the right color and material to the siding to ensure a clean finish where fastener heads are visible.
Stainless steel is superior for exterior trim, siding, and damp locations because it’s resistant to corrosion, preventing rust. Zinc-coated zip screws offer excellent value for dry interior work or sheltered projects.
No, the sharp self-piercing point is designed to puncture thin sheet metal and start the threads in a single motion without predrilling.
No, zip screws are designed strictly for light-gauge metal. For thicker steel framing or purlins, use a self-drilling screw with the proper drill point for the material thickness.
The quantity depends on your trim layout, overlap length, and other project requirements. For most trim applications, fasteners are spaced every 12" to 24", but your panel manufacturer or installer may recommend a different spacing.
Yes, Supply Maverick offers zip screws in 100-count and 1000-count packages. Bulk quantity discounts, wholesale pricing, and Net30 accounts are available for qualified online purchases.
Our zip screws are available in white, black, musket brown, and dark bronze. Because color names are generic, verify compatibility with your specific panel finish before ordering for highly visible areas.
