EnglishWhat Is ZAGO Self Sealing Fasteners?
Updated
selfsealingfasteners.com is the product website for ZAGO, a brand of self-sealing fasteners built around 360° O-ring technology. The site is aimed at buyers and engineers who need leak-proof sealing protection in fastened joints, and it lets visitors browse top fastener categories and shop them directly. It is a product and shopping site rather than a general reference resource, so the most useful way to read it is by product category and by industry application.
What the site offers
The core claim on the site is sealing protection: ZAGO sealing fasteners use 360° O-ring technology to keep a joint leak-proof while still functioning as a fastener. The homepage frames this as "Small Components. Big Impact." — the value is in the seal, not the size of the part.
The site organizes products into shoppable categories, including:
- Phillips Pan Head
- Phillips Flat Head
- Phillips Flat Head 100°
- Slotted Pan Head
The category descriptions give a sense of the range. Phillips flat head screws are described as having a cone shape to fit a countersunk hole, and slotted pan head machine screws are described as made from corrosion-resistant materials for durability. These are the kind of details that matter when you are matching a fastener to an existing hole pattern or to an environment where corrosion is a concern.
Who it is for
The site lists industries that point to demanding sealing environments rather than general hardware use:
| Sector | Why sealing fasteners matter there |
|---|---|
| Military & Defense | Equipment exposed to moisture, dust, and field conditions |
| Aerospace | Pressure and fluid containment in critical assemblies |
| Electronics & Enclosures | Keeping water and contaminants out of housings |
| Offshore Wind | Salt, spray, and weather exposure |
| Medical Devices | Fluid handling and cleanability |
| Robotics & Drones | Compact assemblies that still need ingress protection |
| Marine | Continuous water exposure |
| Energy Generation & Recovery | Fluid and pressure systems |
| Automotive | Fluid lines and underhood environments |
| LiDAR | Sealed sensor housings |
| Industrial Manufacturing | Washdown and process fluid exposure |
| Commercial Lighting | Outdoor and wet-location fixtures |
If your application involves a fastened joint that must also hold a seal — an enclosure lid, a fluid port, a sensor housing — this is the relevant product family. If you only need mechanical fastening with no sealing requirement, a standard fastener will usually do the job at lower cost.
How to use the site to make a decision
- Start from the category list. Match the head style to your tooling and hole: pan head for a flat surface, flat head (including 100°) for countersunk holes.
- Check the material note. The site calls out corrosion-resistant materials on slotted pan head screws; confirm the material suits your environment before ordering.
- Cross-check your industry. Find your sector in the industries list and use the products shown there as a starting point, since sealing requirements differ between, say, marine and electronics enclosure use.
- Verify the seal spec against your requirement. The 360° O-ring is the central mechanism; confirm the O-ring material and the pressure/fluid it will see with the supplier before committing to a production order.
A practical example: if you are sealing an outdoor lighting enclosure, the commercial lighting entry and a pan head or flat head sealing screw are the natural starting points — but the O-ring compound still needs to match the weather and temperature range, which is a question for ZAGO rather than something the category page answers.
Limits to keep in mind
The site presents product categories and industry fit, not a full engineering datasheet on the homepage. Pricing is not shown in the material reviewed here, so do not assume the site is free to order from or that listed products carry published prices — check the shop pages or contact the company for quotes and minimums. For anything safety-critical (aerospace, medical, defense), treat the site as a starting point and get written specifications and test data from ZAGO before design freeze.
