Description
The Open End Blind Rivet is a high-performance, single-sided mechanical fastener engineered for efficient assembly in applications where access to the rear of the material is restricted. Conforming to the GB/T 12618 national standard, this core-pulling model ensures exceptional dimensional consistency and manufacturing quality.
This specific rivet features a "semi-steel" construction, pairing a corrosion-resistant 304 stainless steel body (sleeve) with a high-strength steel mandrel (core). The open-end design allows the mandrel to be pulled through to form the joint, making it the ideal solution for non-sealing structural joints that require superior shear and tensile strength. Equipped with an oval head, this stainless steel blind rivet provides a wide bearing surface to ensure a secure, stable fit across a variety of industrial materials. Because of its durability, installation efficiency, and strong holding power, this stainless steel blind rivet is commonly used in automotive manufacturing, marine equipment, metal fabrication, electrical enclosures, construction panels, and machinery assembly.
Features & Benefits
- Dual Material Construction: The body is manufactured from 304 stainless steel to provide high corrosion resistance and a clean aesthetic, while the core consists of a high-strength steel alloy to withstand the extreme pulling forces required for joint formation.
- Oval Head Design: The dome-shaped oval head distributes clamping force over a larger surface area. This protects softer materials from damage and enhances the overall stability of the joint against high shear forces.
- Consistent Quality and Compliance: Every rivet is manufactured to the GB12618 standard, guaranteeing dimensional accuracy, reliable workmanship, and performance consistency across high-volume batches.
- Rapid Ease of Installation: The core-pulling mechanism allows for permanent, high-strength fastening using a standard riveting tool. This process significantly reduces assembly time compared to traditional threaded fasteners.

FAQ
Q1: What does "Open End" mean for this rivet?
A: The "Open End" refers to the fact that the rivet tail remains open after the mandrel is pulled through. Unlike closed-end rivets, these are designed for general structural joints where a liquid-tight or airtight seal is not a primary requirement.
Q2: What is the difference between an open-end and closed-end blind rivet?
A: Open-end blind rivets allow the mandrel movement for expansion and are suitable for general fastening. Closed-end rivets seal the hole to prevent moisture and contamination entry.
Q3: Why use a steel core with a 304 stainless steel body?
A: This "semi-steel" combination provides the best of both worlds: the 304 stainless steel body offers excellent rust prevention, while the steel mandrel provides the high tensile strength needed to properly "set" the rivet without the mandrel snapping prematurely.
Q4. Is this rivet suitable for marine environments?
A:Yes. Because the external body is made from 304 stainless steel, it provides the necessary corrosion resistance for marine, automotive, and outdoor construction applications.
Q5: Can I install these without specialized heavy machinery?
A: Yes. These rivets are designed for ease of installation using a simple manual or pneumatic riveting tool, making them perfect for both field repairs and assembly line manufacturing.
