What is Hemlock Rivet?
Hemlok rivets are high strength structural rivets. It is mainly used to improve high strength, reliable connections. Compared with traditional rivets, hemlok rivets have greater resistance to shear and corrosion.
Hemlok rivets have an enhanced load bearing area and stability in the riveted area due to the unique extension of the tail. hemlok rivets can join a wide range of dissimilar materials. This includes riveting metal to metal, metal to plastic, and sheet to thick metal. Common applications include automobiles, warehouse shelving and ladders.
Pros and Cons of Hemlok Rivets
Hemlok blind rivets are widely used in critical joints. Let’s find out why hemlok blind rivets are so widely used and what their disadvantages are.
Pros of Hemlok Rivets
- High Strength Performance: hemlok rivets have excellent tensile and shear strength, much higher than standard blind rivets.
- Outstanding vibration resistance: hemlok rivets’ extended tail design and high clamping force ensure that connecting parts will not loosen in high vibration environments.
- Uniform tail extension: hemlok blind rivets have a uniform tail extension that creates a large contact area.
Cons of Hemlok Rivets
- Higher cost: hemlok blind rivets are more complicated to design and require higher materials. Therefore the manufacturing cost and price are relatively high.
- Specialized installation tools are required: there is no way to install hemlok rivets with ordinary pneumatic rivet guns. Specialized structural rivet guns are needed for installation.

Types of Hemlok Blind Rivets
Hemlok blind rivets provide reliable connections primarily to critical areas and can be customized to suit different scenarios. This is why blind rivet manufacturer can offer many types of hemlok rivets.
Rivmate’s hemlok blind rivets offer specialized riveting solutions depending on the actual application.
To help you win the trust of your customers, here are some of the hemlok blind rivets to choose from:
A. Based on Materials
- Carbon Steel Hemlok Blind Rivets：Carbon steel hemlok blind rivets are strong and relatively inexpensive. It has good tensile and shear strength and is suitable for high load and strong connection scenarios.The main advantage of Carbon steel hemlok blind rivets is high strength and low cost, which is suitable for projects with limited budget.
- Stainless Steel Hemlok Blind Rivets：Stainless steel hemlok blind rivets provide excellent corrosion resistance in addition to high strength. It is ideal for use in harsh environments. Commonly used grades include 304 and 316 stainless steel, with 316 stainless steel being more resistant to corrosion.
- Aluminum Hemlok Blind Rivets：Aluminum hemlok blind rivets are very lightweight, making it an excellent choice for lightweight applications. It has good corrosion resistance and medium strength. The durability of hemlok blind rivets can be further enhanced if anodized.
B. Based on Rivet Head Types
- Dome Head Hemlok Blind Rivets：Dome head hemlok blind rivets will have the head of the rivet protruding slightly from the surface of the parent material after installation. Primarily used for general structural joints, they are suitable for a wide range of materials including metals, plastics and composites.
- Countersunk Head Hemlok Blind Rivets：Countersunk head henlok blind rivets are rivets with a flat head design. The rivet head can be inserted into a countersunk hole in the base material and is flush with the surface of the base material during installation. Common countersunk head angles are 90° and 120°.
Applications of Hemlok Blind Rivets
Hemlok blind rivets are characterized by high strength, reliability and resistance to loosening. Therefore, they are widely used in applications that require high shear resistance, tensile strength, corrosion resistance, and stable connections under vibration or harsh environments. Below are the main applications for hemlok rivets.
Automobile Industry
Hemlok Rivets are widely used in automobile manufacturing, especially in parts that require high structural stability and vibration resistance.
- Body frames: Used for the connection of load-bearing parts such as automobile frames, reinforcing beams, chassis structures, etc., providing high shear and tensile strength.
- Door and window frames: connecting the door skeleton with the exterior metal panels to ensure that they do not loosen during high-frequency switching.
- Engine guards and chassis protection plates: Provide a strong connection that adapts to the high temperature and high vibration conditions of engine operation.
- Seat fixing assembly: connects the seat bracket with the interior skeleton to ensure passenger safety and comfort.
Building & Infrastructure
Hemlok Rivets are used in a wide range of applications in building structures and infrastructure, especially where resistance to wind pressure, vibration and long-term stability is required.
- Curtain wall systems: connecting metal panels and supporting frames on the exterior of buildings to ensure curtain wall stability.
- Structural steel connections: for high strength fixing of thin steel or aluminum alloy plates.
- Bridge Maintenance and Repair: For the connection of lightweight bridge components to provide shear strength.
- Rail & Sign Support Structures: to connect traffic signs, light poles or other support structures.
Appliances and Home Appliances
Hemlok Rivets are commonly used in the appliance and home appliance industry to join metal housings, brackets and decorative panels.
- Washing machines and dryers: fixing of the housing and internal support frames for high frequency vibration.
- Air conditioning systems: connecting metal panels to cooling supports, providing stable mechanical support.
- Refrigerator and appliance panels: installing external decorative panels to ensure the stability of the appearance and solid connection.
Industrial Equipment and Machinery Manufacturing
In industrial manufacturing, Hemlok Rivets are commonly used to secure machine parts, equipment housings and vibration-prone assembly areas.
- Machine Enclosures and Shrouds: Attachment of external equipment shields to protect internal components from external damage.
- Pipe supports: Provide a fixed connection for pipe supports to accommodate dynamic loads in industrial environments.
- Electrical equipment cabinets: connects the frame and panels of electrical cabinets to provide stabilizing support.
- High vibration equipment components: such as pumps, compressors components fixed to prevent loosening caused by vibration.
