About this item
- A2-304 STAINLESS STEEL BODY & MANDREL – RUST-FREE PERFORMANCE INDOORS & OUT Both the rivet body and mandrel are manufactured from A2-304 stainless steel — delivering full corrosion resistance throughout the entire fastening, not just the visible head. Unlike aluminium-body rivets with steel mandrels that can rust and stain over time, these all-stainless rivets maintain a clean, rust-free finish in wet, coastal, marine, and outdoor environments, making them the professional choice wherever long-term appearance and integrity matter.
- DIN 7337 TYPE A DOME HEAD – THE INDUSTRY STANDARD FOR BLIND RIVETING Conforming to the internationally recognised DIN 7337 Type A standard, these open-end dome head blind rivets provide a proven, reliable and consistent fastening every time. The dome head profile distributes clamping load evenly across the material surface without deforming, cracking, or marking painted, glazed, or coated finishes — ideal for visible or aesthetic applications where a neat, professional result is required.
- 5mm x 20mm – COMPATIBLE WITH ALL STANDARD 5mm POP RIVET GUNS Sized at 5mm diameter x 20mm length, these rivets fit directly into all standard pop rivet guns and pneumatic rivet tools. No adapters required. The 20mm length suits a typical grip range of 2–6mm, making them ideal for fastening light to medium gauge sheet metal, steel plate, aluminium panels, plastics, and composite materials.
- BLIND INSTALLATION – SINGLE-SIDED ACCESS, FAST & PERMANENT As a blind pop rivet, installation requires access from one side only — making these the go-to fastener wherever the rear of the joint is inaccessible. Simply drill a 5mm hole, insert the rivet, and pull the mandrel with your rivet gun. The body expands to clamp both materials together permanently in under five seconds, with no secondary fasteners, adhesives, or rear access needed.
- PACK OF 50 – WIDE APPLICATION ACROSS TRADE, AUTOMOTIVE, MARINE & DIY Each pack contains 50 off 5mm x 20mm stainless blind rivets — sufficient for a wide range of professional and DIY projects including automotive bodywork, boat and marine deck fittings, caravan and motorhome panels, guttering and roofline, HVAC ductwork, signage, sheet metal fabrication, and general construction. Available across a full range of diameters and lengths for complete rivet size coverage.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
