Stainless Steel Snap Button Ø13 mm for Boat Covers and Canvas

This stainless steel Ø13 mm button is the cap (top part) of a standard marine snap fastener system for canvas and covers. It is used to secure fabric (such as a boat cover, sprayhood, or bimini top) to a hard surface or frame by mating with a corresponding stud mounted on the boat. Manufactured entirely from 304/316 stainless steel, this snap button is completely corrosion-resistant and will retain its strength and shiny appearance even after years of use in harsh saltwater environments.

Key advantages:

• Reliability & Strength: The metal construction of the snap ensures a firm, positive engagement – when you press the male stud and this female button together, they “snap” tight and won’t pop off due to vibration or wind. The 13 mm cap diameter is a marine industry standard (often used in common canvas snap systems like Tenax, DOT Fasteners, etc.), meaning this button can directly replace worn or corroded snaps on your equipment with no compatibility issues.
• Corrosion-Proof: Unlike ordinary plated steel or even brass snaps, this stainless steel snap will not rust. This is crucial for marine use – even if left damp under a cover all winter, the button stays rust-free, avoiding ugly rust stains on your canvas and ensuring the fastener always opens and closes smoothly.
• Universal Application: Suitable for fastening all kinds of marine canvas – from boat covers and tonneau covers, to bimini tops, sprayhoods, dodgers, and sailcloth attachments. You’ll also find these snaps used on RV awnings, convertible car tops, outdoor furniture covers, and more – anywhere a strong yet removable connection is needed. This particular size and style is ubiquitous in boating, so it’ll likely match the existing snaps on your boat’s canvas.
• Easy Installation: Installing a snap button involves punching a small hole in the fabric, inserting the two parts (cap and socket) of the button, and then clinching them together. This can be done with a simple handheld snap setter tool or a hammer and die set, or professionally with a press. It’s a quick process – once set, the button is permanently affixed to the fabric. On the finished side, you’ll see the smooth 13 mm dome of the button, giving a clean, professional look, while the socket part is crimped on the underside of the fabric.
• Maintains Grip Over Time: The internal spring of the snap (in the socket) is designed for repeated use. You can snap and unsnap your canvas many times, and it will remain snug. Stainless steel’s spring properties ensure it doesn’t deform or lose tension easily – unlike cheaper snaps that might loosen after a season, these will continue to “click” securely.

Usage recommendations: To make a complete snap fastener, you’ll need this button (the top part on the fabric) and a matching bottom part – usually a stud or eyelet that attaches to the boat (via screw, rivet, or other means). Ensure you use compatible sizes – a 13 mm cap usually pairs with the standard size studs. When installing on fabric, consider using a reinforcing washer on the backside of the fabric (often included in snap kits) which sandwiches the fabric between the cap and socket; this prevents the snap from tearing out under high stress.

Once properly installed, you get a quick-release connection – simply press the canvas snap onto the stud and it “clicks” on. To remove, you typically peel the canvas away by lifting the edge of the snap (many covers have a little tab or loop of webbing near the snap for this purpose). This makes covering and uncovering your boat very convenient.

In summary, the stainless steel Ø13 mm snap button is a critical small component for any marine canvas setup – it keeps your cover securely fastened, taut, and protected, yet allows easy removal when needed. Investing in quality stainless snaps means you won’t face issues with rust stains or failure, ensuring your covers and enclosures stand up to the rigors of the marine environment and continue to do their job season after season.
