Best Screws With Built-in Washers for Roofing, Repairs, and Projects
The best match for a screw with a built-in washer is a roofing screw with a bonded EPDM sealing washer. It combines the screw and sealing surface in one fastener. For furniture feet, the Eoppen kit pairs rubber bumpers with screws and built-in stainless steel washers. The other kits below include separate washers or assorted fasteners, so they are better for general repairs than for applications requiring an integrated sealing washer.
| Product | Best For | Washer Type |
|---|---|---|
| kvohlum roofing screws | Metal roofing and sealing | Bonded EPDM washer |
| Eoppen rubber feet kit | Furniture and appliance feet | Built into rubber feet |
| Bonost assortment | Broad repair projects | Separate washers included |
| ALLWIN assortment | Basic home repairs | Separate washers included |
| Fasvicna cup washers | Flush decorative fastening | Separate countersunk washers |
kvohlum Metal Roofing Screws With EPDM Washers
These #10 x 3/4-inch self-tapping roofing screws are the closest match for someone searching for a screw with a built-in washer. Each screw has a metal washer bonded to an EPDM rubber washer. The product description says the rubber washer forms a seal when the screw is tightened and can help prevent leaks, loosening, and damage to the contact surface.
Best for: Metal roofing or sheet-metal fastening where a washer that seals around the screw is needed. The package includes 50 carbon-steel, zinc-plated screws and a hex bit socket.
Limitation: These are a specific #10 size and 3/4-inch length, so check the required fastener dimensions and material before choosing them. The listed features do not specify a drill-point capacity or compatibility with a particular roofing system.
Eoppen Rubber Feet With Built-In Washers
This kit is not a general-purpose screw assortment, but it has a built-in washer feature for a defined job: attaching rubber feet to furniture or appliances. The rubber feet contain stainless steel washers, and the kit includes stainless steel screws. The rubber is described as wear-resistant and non-slip.
Best for: Buyers replacing or adding feet to furniture, appliances, or cutting boards. It includes three foot sizes—0.6, 0.8, and 1 inch—and 62 screws, with pieces packed in reusable boxes.
Limitation: The screws are intended for installing the included feet, rather than serving as standalone washer-head fasteners for roofing or sheet metal. The instructions call for pilot holes and a Phillips screwdriver.
Bonost Nuts, Bolts, Screws, and Washers Kit
Bonost’s 2,300-piece assortment covers a wider range of fastening needs than a dedicated washer-head screw pack. It includes SAE and metric bolts, nuts, and washers, plus Phillips-head sheet-metal screws, Torx-drive wood screws, and matching anchors. The carbon-steel hardware has zinc coatings, and the pieces are individually packaged in a stackable case.
Best for: DIYers who need multiple fastener types on hand and can use separate washers where appropriate. Choose this if general repair coverage matters more than having a washer integrated with each screw.
Limitation: The listed features do not identify the screws as having built-in washers. This assortment should not be treated as a substitute for a bonded sealing washer when a leak-resistant roofing connection is required.
ALLWIN Bolts, Nuts, and Washers Assortment
This 120-piece kit includes 40 bolts in six sizes, 40 nuts in three sizes, and 40 washers in three sizes. The hardware is described as galvanized iron with rust resistance, and a clear organizer box keeps the components sorted.
Best for: Basic home repairs that call for a bolt-and-nut connection with a separate washer. The included organizer can help keep the sizes together between projects.
Limitation: This is a metric bolt, nut, and washer kit, not a selection of screws with integrated washers. The product details do not give the dimensions for each size, so verify fit before starting a repair.
Fasvicna #8 Countersunk Cup Washers
These 304 stainless-steel cup washers are separate components, not screws with built-in washers. Their countersunk profile is designed to work with oval- or flat-head screws for a flush finish. The listed dimensions are a #8 inner diameter of 0.19 inch and an outer diameter of 0.52 inch. The product description also notes smooth, burr-free surfaces and corrosion resistance.
Best for: Visible assemblies, decorative fixtures, or panels where a countersunk washer can protect the surface and provide a neat finish.
Limitation: The washer must be paired with a compatible screw, so it does not provide the one-piece convenience or bonded seal of a roofing screw.
Buying Guide: How to Choose a Screw With a Built-In Washer
Do you need an integrated washer or a separate one?
An integrated washer stays attached to the fastener, reducing the number of loose parts to handle. A bonded rubber washer, such as the EPDM washer on the kvohlum roofing screws, is more relevant when sealing is important. A separate flat or cup washer offers flexibility, but you must choose a washer and screw that fit each other.
What should you check before buying?
- Application: Match roofing screws to metal-roofing or sheet-metal tasks; choose dedicated rubber feet for furniture or appliance bases.
- Dimensions: Confirm screw diameter and length, washer dimensions, and the receiving material before purchase.
- Washer function: EPDM is described as a sealing material in the roofing screw listing. Flat washers spread load across a wider area, while countersunk washers support a flush-style finish.
- Material and exposure: Compare the listed materials and coatings with the project environment. Stainless steel, zinc-plated steel, and galvanized iron are not interchangeable descriptions.
- Quantity and assortment: A focused pack can suit a defined job; a kit with multiple sizes can be useful for varied repairs but may not contain integrated washers.
Frequently Asked Questions
What does a screw with a built-in washer mean?
It is a screw supplied with a washer attached or integrated into the fastener assembly, rather than requiring a separate loose washer. Some designs also use a rubber layer for sealing.
Are roofing screws with rubber washers waterproof?
The kvohlum listing says its bonded EPDM washer forms a tight seal when tightened and can help prevent leaks. Correct installation and suitability for the specific roofing system still matter.
Can I use a flat washer instead of a built-in washer screw?
A separate flat washer can distribute load and protect a surface, but it is not automatically a sealing washer. Use a washer designed for the function the project requires.
Are Eoppen’s screws general-purpose washer-head screws?
No. The kit pairs screws with rubber feet that have built-in stainless steel washers and is described for installing those feet on furniture and appliances.
How do I choose the right screw length?
Check the material thickness, required engagement, and product specifications for the project. The listed roofing screw is 3/4 inch long, but that dimension may not suit every installation.
