kvohlum #10 x 3/4″ Metal Roofing Screws with Rubber Washer
Best for outdoor metal roofing and thin-sheet metal, these self drilling screws pair carbon steel with a zinc-plated surface for corrosion resistance. The EPDM washer forms a tight seal to prevent leaks and loosening. Hex bit socket included for quick installation. Not ideal for heavy structural wood use where longer screws are required.

Best for metal-to-metal connections in roofing and outdoor projects, these 410 stainless steel screws with 304 stainless steel washers and EPDM seals resist rust and wear. The 1″ length provides extra bite for thicker sheets. Choose this if you need higher corrosion resistance and longer engagement, but be mindful of magnetic property of 410 stainless steel.
mxuteuk 230PCS #8 Self Tapping Screws with Rubber Washers
Best for versatile DIY projects involving metal, plastic, and wood, this 230-piece set includes five screw sizes with rubber washers and a clear storage box. Made from 410 stainless steel for good corrosion resistance and magnetic properties. It’s a solid all-around kit, though the presence of magnetic 410 stainless steel is something to note for sensitive tools.
VGBUY 150Pcs Self Drilling Screws Assortment Kit
Best for general metal projects requiring a mix of sizes (#8 to #10, 1/2″ to 1-1/2″), this kit uses 410 stainless steel for corrosion protection with an accessible hex washer head. The assortment is ideal for wardrobe or small fabrication tasks. Avoid this if you need longer screws for thicker materials beyond 1-1/2″.
Buying Guide
Key considerations help ensure you pick the right self tapping screw with a washer for your project.
Material and corrosion resistance
Look for stainless steel or zinc-plated carbon steel to withstand outdoor exposure. Stainless options offer better corrosion resilience but may be magnetically affected. Zinc-plated carbon steel is adequate for many indoor or covered applications.
Washer type and sealing
EPDM washers provide a watertight seal and resist wear. Ensure the washer size matches the screw head and the metal surface to distribute pressure evenly and prevent leaks.
Head style and drive
Hex washer heads offer better torque transfer and grip with standard wrenches or bit drivers. Self drilling tips reduce the need for pilot holes, saving time for metal-to-metal projects.
Size and length
Choose a length that provides enough thread engagement in the base material. Too short a screw may slip; too long can damage the back side of thin materials.
Environment and application
For roofing and exterior metal, prioritize rust-resistant finishes. For indoor furniture or fixtures in dry environments, standard zinc-plated screws may suffice.
Storage and organization
Sets that come in labeled cases help you quickly grab the correct size during work, reducing downtime and the risk of cross-sizes.
Compatibility and safety
Verify the screw’s drive type matches your tool and that the washer won’t interfere with the fixture’s surface or concealment needs.

FAQ
- Q: Do self tapping screws require pilot holes? A: Self tapping screws are designed to drill their own hole in metal, though very thick materials may still benefit from a pilot.
- Q: Are EPDM washers universal for all screws? A: EPDM is common and suitable for many screws, but verify washer size and compatibility with the screw head.
- Q: Can these screws be used with wood? A: They can, but intended use is metal-to-metal or metal-to-wood in some kits; check the product description for wood suitability.
- Q: Is magnetic stainless steel a concern? A: Some 410 stainless steel screws are magnetic; consider when working with sensitive magnetic equipment.
- Q: What thickness can these screws handle? A: Wall thickness varies; refer to the thread length and plate thickness ranges listed in each product’s specifications.
- Q: Do these include a driver bit? A: Some kits include a hex bit socket; others may require a corresponding bit tool you already own.
