Premium Blind Rivets: Reliable Fastening Solutions from Handan Bolt

At Handan Bolt, we specialize in the manufacturing and export of high-performance Blind Rivets (also known as Pop Rivets). Situated in Yongnian, China’s “Capital of Fasteners,” our factory produces millions of rivets monthly, supplying construction, automotive, and industrial sectors worldwide. Whether you need standard open-end aluminum rivets or heavy-duty structural rivets, we offer consistent quality at factory-direct prices.

What is a Blind Rivet?

A Blind Rivet (Read more on Wikipedia) is a tubular fastener with a mandrel through the center. It is designed to join two pieces of material together where there is no access to the back side (hence the name “blind”). They are installed using a riveting tool that pulls the mandrel, expanding the rivet body to clamp the materials securely.

Our Product Range and Classifications

We manufacture a diverse range of blind rivets to suit various applications. Our production capabilities include:

1. Head Styles

• Dome Head (Standard): The most common head style, providing enough bearing surface for most applications.
• Countersunk Head (CSK): Used where a flush surface is required after installation.
• Large Flange Head: Features a larger head diameter to spread the load over a wider area, ideal for fastening soft or brittle materials like plastic and wood.

2. Body Types

• Open End Type: The most widely used type for general industrial applications.
• Closed End (Sealed) Type: The mandrel head is retained inside the sealed body, making it waterproof and gas-tight.
• Peel Type: The body splits into four “petals” upon setting, perfect for joining soft materials like rubber or insulation.
• Grooved Type: Designed for fibrous materials like wood or plastic where the grooves bite into the material.

Material Combinations (Body / Mandrel)

Selecting the right material combination is crucial for preventing galvanic corrosion and ensuring structural integrity. We offer:

• Alu / Steel (AS): Aluminum Body with Carbon Steel Mandrel. The most popular choice for general use due to its lightweight and cost-effectiveness.
• Steel / Steel (SS): Carbon Steel Body and Mandrel. Offers higher shear and tensile strength for heavy-duty fastening.
• Stainless / Stainless: 304 or 316 Stainless Steel for both parts. Provides superior corrosion resistance for marine and food industry applications.
• Alu / Alu: Full Aluminum rivets for lightweight applications requiring corrosion resistance.

Technical Standards and Quality Control

Our blind rivets are manufactured strictly according to international standards:

• DIN 7337 (German Standard)
• ISO 15977 / 15979 (International Standard)
• IFI 114 (American Standard)

Every batch undergoes rigorous testing for shear strength, tensile strength, and mandrel break load to ensure smooth installation and lasting hold.
