Lap screws from SFS: Top choices & FAQs
When it comes to securing overlapping panels, the stakes are high. Constant movement at these points can easily compromise weaker fasteners, leading to costly damage and repairs. That's where lap screws prove invaluable. Engineered with a larger diameter, lap screws offer superior shear strength, making them the go-to solution for reliable, long-lasting engineering.
Consider the critical role of lap screws in keeping your roof panels tightly secured through wind, rain, and the test of time. These small but mighty fasteners are designed specifically for areas where panels overlap, ensuring reliable connections with minimal movement. While they're most commonly found on roofs, their versatility extends to sidewalls and any other overlapping panel applications, providing peace of mind wherever they're used.
How do the types of lap screws differ?
SFS offers a few different types of lap screws, that differ based on their intended application, including:Â
Metal to metal — for installation in metal panels.
Metal to wood — for installation in wood panels.Â
Different head styles — depending on torque needs. Head styles include HWH (Hex Washer Head), Cupped HWH, MAC, and ZAC.
Washer types — depending on your weather protection needs. Washers include control seal (CS) and bonded.
Carbon steel, 410 stainless, 304 stainless — depending on corrosion resistance needs.
We engineer a range of lap screw options to accommodate diverse project needs influenced by the materials being attached and the environmental conditions. For example, for better corrosion resistance, we offer bi-mets and full stainless fasteners for dissimilar metal connections to prevent galvanic corrosion.

Lap screw FAQs
What’s the difference between lap screws and stitch screws?
Sometimes these fasteners are called “lap screws” because they’re used for overlapping panels. Other times they’re called “stitch screws” because they stitch panels together.
Ultimately, lap screws and stitch screws are two names for the same thing, though different engineers may default to one or the other. However, these terms can be used interchangeably.
How do lap screws differ from other types of fasteners?
Typically, lap screws have a thicker diameter but are shorter. The larger diameter of these fasteners provides enhanced shear performance.Â
Their unique design and enhanced strength sets these fasteners apart from standard screws and makes them the best option for securing overlapping panels on roofs or sidewalls.
When should you use a lap screw instead of a traditional fastener?
Due to their short length and wide diameter, lap screws are best used for installing overlapping panels, such as for roofs or sidewalls. Lap screw dimensions provide increased shear strength, ensuring the fastener stays in place, even when panels move around due to wind or other forces.
What should you consider when selecting a lap screw for their project?
When choosing a stitch screw, consider your:
Corrosion needs
Substrates installed into
Budget
Required strength properties for codes and approvals
Your application will determine which material and head style you select. If you aren’t sure which fastener is best for your project, reach out to our team of experts at (610) 376-5751.Â
When should you choose bi-met or stainless vs. carbon steel lap screws?
Carbon steel fasteners provide a standard level of corrosion resistance. Meanwhile, bi-met provides the drill performance of carbon steel with the corrosion resistance of a stainless steel part.
How are SFS’s lap screws superior to screws from competitors?
SFS fasteners feature washer sealing capabilities. Additionally, our drill points and heads offer quick and easy installation. Aesthetics is just as important as fastener strength and installation ease. We offer color matching, ensuring lap screws blend in with the panels they’re installed in.
Finally, SFS offers a long-life fastener limited-warranty on parts. You can install with confidence, knowing that your parts are protected.
