Key Features
1. Full Stainless Steel Construction
Body and Mandrel Both the rivet shell and the pull mandrel are made of 304 stainless steel. That means no rust bleed onto your workpiece and no corroded stem left inside the joint. For outdoor, marine and high-humidity environments, stainless steel blind rivets keep panels clean and corrosion-free long after ordinary rivets start to streak.
2. Countersunk (CSK) Head
Sets Flush With the Surface The 120° countersunk head sits flush with the workpiece, leaving a smooth, snag-free finish. Nothing protrudes to catch hands, tools or cargo, and two surfaces can sit flat against each other with no gap — which is why countersunk head blind rivets are the standard for panels, frames, signage and vehicle bodies.
3. Blind Installation From One Side Only
As a blind rivet, it installs from the front side with no access to the back of the material. No bucking bar, no second person, no disassembly. That makes it a fast, reliable fastening solution for closed sections, channels, tubes and pre-assembled frames — anywhere the rear side is simply unreachable.
4. Strong, Vibration-Resistant, Permanent Joint
the rivet forms a mechanical lock that holds tight under vibration — the same vibration that slowly works screws loose. Stainless steel gives it solid shear and tensile strength, so the joint stays secure for the service life of the product. It never backs out and never needs retightening.
5. Versatile Across Sheet Metal and Thin
Wall Applications From ductwork and gutters to machine guards, marine hardware, food-processing equipment and automotive panels, one fastener covers most thin-gauge metal jobs. Available in a range of diameters and grip ranges, so you can match the rivet to your material thickness instead of forcing a one-size-fits-all fix.
Production Process
Production runs under a strictly controlled ISO 9001 quality system from the first step to the last.Stainless steel wire is inspected against the material spec when it arrives, then cold-formed into rivet bodies and mandrels, polished and surface-treated. After assembly, every batch goes through dimensional and function testing before packing, and records are kept at each stage so any batch can be traced back to its raw material. The point of all that paperwork is simple: you receive the same rivet — same dimensions, same finish, same strength .
Our Service
1. Custom sizes, made to your spec This rivet is available in standard diameters and grip ranges from stock — or we'll produce non-standard lengths to your drawing. Tell us your material thickness and we'll match the rivet to it.
2. Your choice of 304 or 316 stainless Both the body and the mandrel are stainless, and you decide which grade you need. 304 covers most indoor and general outdoor use; 316 adds extra corrosion resistance for marine, coastal and chemical environments.
3. Samples before you commit Test the actual rivet in your own assembly before ordering in volume. We'll send samples sized to your hole and your sheet thickness, so what you approve is exactly what you get in bulk.
4. Brand label and custom packaging Your logo, your label, your spec sheet — we pack this rivet the way your customers expect to receive it, from retail blister packs to bulk boxes and container loads.
5. Consistent quality, order after order Every batch goes through our own forming, treatment and testing line before it's packed. The rivets in your fifth order should behave exactly like the ones in your first.
6. Technical support, before and after the sale Not sure about hole size, grip range or whether 304 or 316 fits your job? Ask us. We'll recommend the right spec based on your material and environment
