Standing seam roof fasteners need a low profile. Under a concealed metal roofing panel, a tall head can crowd the clip, leave a bump, or make the panel harder to seat cleanly. That’s why pancake screws are the go-to choice for many jobs requiring standing seam clips.
Supply Maverick carries #10 pancake screws and stainless steel rivets for standing seam roofing, clip lock panels, trim work, ridge caps, gutters, and downspouts. For wood substrate, start with #10 zinc-plated pancake screws or #10 stainless steel pancake screws. For steel-to-steel work, choose the #10 zinc-plated self-drilling pancake screw. For thin sheet metal connections, use #43 full stainless steel rivets in painted or mill finish options.
Most orders placed before 12 noon EST ship the same day, and Supply Maverick ships across the United States, Canada, Australia, and New Zealand, with bulk quantity pricing available on product pages.
Fastener choice usually starts with the material below the clip. Wood deck calls for a wood application screw, steel framing calls for a self-drilling point, and thin metal trim work calls for a rivet rather than a clip screw.

Pancake head screws sit flatter than standard hex-head roofing screws. On a standing seam system, that low head helps the clip and the panel sit closer to the deck or framing. The result is cleaner fastening around clip locations, especially on clip lock panel systems.
Check the panel manufacturer’s instructions before ordering. Clip type, clip spacing, substrate, and fastener material should all match the roof system being installed.
A standing seam fastener has to match both the roof system and the substrate. A small mismatch can strip the hole, leave the clip sitting higher than it should, and slow down the whole crew.
Wood substrate work uses a metal-to-wood pancake screw. The #10 zinc-plated pancake screws and the #10 stainless steel pancake screws in this category are designed to secure standing seam clips to a wood substrate. They’re commonly used with clip lock standing seam panels where a low-profile fastener is needed under the panel system.
Steel-to-steel work needs a self-drilling point. The #10 zinc-plated self-drilling pancake screw is designed for fastening into steel, eliminating the extra step of pre-drilling in many steel applications. Before installation, confirm that the screw length and point style match the steel gauge and the panel system specs.
Head style matters since standing seam roofing hides the fastener below the finished panel. A pancake head spreads the load while staying low, reducing panel interference around the clip.
For exposed fastener panels, washered roofing screws are the better match, whereas for standing seam clips, pancake screws are usually the cleaner choice. If you’re looking for more low-profile screw options, shop the full pancake screws category.
Zinc-plated pancake screws work well for many standard standing seam clip installations. Stainless steel pancake screws are used when the project specs call for stainless steel or when corrosion resistance is a higher priority. For trim and accessory details, stainless steel rivets give you a clean, low-profile fastening option for thin metal.
| Material | Best fit | Product example |
| Zinc-plated steel | Standard standing seam clip fastening into wood | #10 Pancake Screws Zinc-Plated |
| Zinc-plated self-drilling steel | Standing seam clip fastening into steel | #10 Pancake Screws Zinc-Plated Self-Drilling |
| 300 series stainless steel | Wood substrate clip fastening with stainless steel material | #10 Pancake Screws Stainless Steel |
| 304 stainless steel | Thin metal connections on trim, ridge caps, gutters, or downspouts | #43 Full Stainless Steel Rivets |
Most standing seam roof systems use concealed clips to hold the panels in place. The clip gets fastened to the deck or framing, then the panel locks or seams over the clip. Because the fastener sits below the visible roof surface, a low head profile is important.
Pancake screws handle the clip fastening side of the job. They’re especially useful where the panel needs to sit flat over or near the fastener head. Rivets handle a separate part of the roof assembly. Use them for sheet metal accessories where two thin metal pieces need to be fastened together, such as a ridge cap connection or a gutter detail.
If your roof uses exposed fastener panels, shop washered metal roofing screws in the fastener category.
Use this quick guide to get the right product faster when you already know the substrate or the detail being fastened.
| Project need | Recommended product | Why it fits |

For help choosing between these options, contact Supply Maverick with the panel style, substrate, screw length, and order quantity. A little information up front makes the fastener match easier.
Supply Maverick is the e-commerce division of Mid-Michigan Metal Sales, so the product mix is built around metal roofing work rather than general hardware. That matters when you need a specific pancake screw, a stainless steel fastener, or a painted rivet for a roof detail.
Fast shipping helps keep the job moving. Most orders placed before 12 noon EST ship the same day, and bulk quantity pricing is shown directly on product pages. Contractors can also ask about wholesale pricing, bulk discounts, and Net 30 accounts for online purchasing.
Homeowners are welcome here, too. If you’re repairing a standing seam detail or matching fasteners for a smaller project, the product pages list sizes, materials, bag counts, and application notes in a straightforward way.
Standing seam roofs commonly use low-profile pancake screws with concealed panel clips. This category also includes stainless steel rivets for thin metal accessories such as ridge caps, gutters, and downspouts.
Yes. Pancake screws are commonly used for standing seam clip work as the head sits low, allowing the panel system to lay cleanly over the fastened clip. Supply Maverick offers zinc-plated, self-drilling, and stainless steel pancake screw options for standing seam applications.
Zinc-plated pancake screws are a practical choice for many standard clip-fastening jobs. Stainless steel pancake screws are used when the project calls for stainless steel material or stronger corrosion resistance. Always match the fastener material to the panel manufacturer’s requirements.
Standing seam roof fasteners can be used with wood or steel when the fastener is made for that substrate. The zinc-plated and stainless steel pancake screws in this category are designed for wood substrate applications. The self-drilling zinc-plated pancake screw is made for steel-to-steel fastening.
These screws are for low-profile standing seam clip applications. Exposed fastener panels usually use washered metal roofing screws.
Clip spacing should come from the panel manufacturer’s instructions, the project plans, or a qualified local installer. Wind load, panel style, roof slope, and substrate all affect the fastening schedule.
Supply Maverick’s standing seam pancake screws are sold in 250-piece bags. The zinc-plated metal-to-wood option is available in 1-inch, 1-1/2-inch, 2-inch, 2-1/2-inch, and 3-inch special order sizes. The stainless steel and self-drilling options are available in 1-inch and 1-1/2-inch sizes.
Rivets can be used to fasten thin metal accessories on a standing seam roof, including ridge caps, gutters, and downspouts. Supply Maverick’s #43 full stainless steel rivets are open-end blind rivets designed to attach two thin pieces of metal with a low-profile finish.
