Choose Hemlock Rivets by Size
Hemlock Rivets come in various lengths to accommodate different sheet thickness ranges. Selecting the correct riveting range ensures a more secure connection. This also helps minimize issues such as loosening, rework, and failed riveting. Rivmate can assist you in selecting the appropriate specifications based on your sheet thickness, hole diameter, and application.
4.8mm Hemlock Rivets
The hole diameter ranges from 4.9 to 5.1 mm, and Hemlock Rivets can be used for riveting in the range of 1.5 to 13.5 mm. This minimizes issues such as reduced panel strength and unstable connections caused by excessively large holes, while maintaining a compact product appearance.
6.4mm Hemlock Rivets
Hemlock Rivets have a hole diameter of 6.6–6.8 mm. They accommodate a wider range of sheet thicknesses, with a riveting range of 1.5–26.0 mm. This reduces the complexity of inventory management and inventory pressure caused by significant variations in sheet thickness.
7.8mm Hemlock Rivets
The hole diameter is 8.1–8.3 mm. Suitable for products with larger mounting holes. The riveting range is 4.0–16.0 mm. Hemlock Rivets provide better hole-filling performance. They reduce issues such as hole loosening and uneven stress distribution on the joint surface.
9.8mm Hemlock Rivets
The largest available hole diameter range is 10.0–10.4 mm, as standard sizes cannot provide sufficient joint strength. Hemlock Rivets are designed for a range of 4.0–22.0 mm. They are suitable for heavy machinery, large metal structures, and high-load-bearing applications.
Choose Hemlock Rivets by Head Type
Different Hemlock Rivet head types are suitable for different assembly locations. Choosing the right head type can reduce processing costs, assembly interference, and the risk of rework. As a professional manufacturer, we can help you select the correct Hemlock Rivet head type based on your needs.

Rivmate can then assist you in confirming the most suitable Hemlock rivet specifications. This helps minimize the risk of selection errors, inconsistent riveting results, and subsequent after-sales complaints before you proceed with bulk purchasing.
2.Can Hemlok rivets be used in marine applications?
Yes. However, you need to select the appropriate materials and surface treatments based on the specific marine environment in which your product will be used. It is important not to simply assume that all Hemlock rivets are suitable for marine applications.
If your application involves only humid environments, outdoor equipment, marine hulls, or marine equipment accessories, Hemlock rivets can be considered as a structural fastening solution. Hemlock rivets inherently offer good mandrel locking, vibration resistance, hole-filling capability, and sealing performance. RIVMATE previously supplied an Italian client who required Hemlock rivets installed on a ship to achieve a waterproof rating of IPX7.
3.How to order custom-sized Hemlok rivets?
If you wish to order custom-sized Hemlock rivets, you will need to provide complete application details so that we, as your supplier, can professionally assess whether the size, material, grip range, and installation results are suitable for your needs.
You will need to provide the dimensions, riveting range, hole diameter, material, surface finish, application scenario, and order quantity. If you have drawings or samples, you can send them directly to Rivmate for evaluation. Rivmate can help you confirm the appropriate specifications and structure before mass production, reducing the risk of selection errors and unstable riveting.
4.What industries commonly use Hemlok rivets?
If your product requires high-strength fastening, vibration resistance, anti-loosening properties, hole-filling capability, or a certain level of sealing performance, you may want to consider using Hemlock rivets. Hemlock rivets are suitable for structural fastening applications that demand higher performance than standard open-end blind rivets.
There are many applications for Hemlock rivets across various industries, such as trucks/trailers, HVAC equipment, industrial machinery, heavy-duty sheet metal, outdoor metal enclosures, and photovoltaic mounting systems.
Because Hemlock rivets lock via thread interference with the mandrel, they provide a more stable locking mechanism and vibration-resistant connections.
5.What are common issues with Hemlok rivet installations
The most common issues encountered during the installation of Hemlock rivets are generally not due to the rivets themselves being “unusable.” Rather, they stem from a failure to match the appropriate grip range, hole size, installation tool tension, material selection, and mandrel structure. Hemlock rivets are structural blind rivets and are more sensitive to installation conditions than standard open-end blind rivets.
During installation, you should be mindful of issues such as insufficient tool tension, mismatched grip range, holes that are too large or too small, the mandrel not being properly locked, unstable blind-side forming, loose rivet cores, and damaged surface coatings.

What are Hemlock Rivets?
Hemlock Rivets are structural pop rivets, which can also be considered high-strength blind rivets of the Hem-Firm/Hemlok type. Hemlock Rivets are not ordinary open-end pop rivets. Ordinary pop rivets are generally intended for general fastening applications. Hemlock Rivets are better suited for applications requiring high strength, vibration resistance, and superior structural stability.
If you encounter the following issues during assembly, Hemlock Rivets may be a better fit for you:
- Standard rivets lack sufficient strength
- Prone to loosening after vibration
- Unusual noises occur after riveting
- Slight deviations in product hole positions
- Unstable connections in thin or multi-layer panels
- Core rod detachment affects product quality
- Products require higher structural connection strength
The Core Architecture of Hemlock Rivets
① Body
The body is the primary component that creates the clamping force and the blind-side bulge. During installation, the body forms a large bearing area on the back of the workpiece. Hemlock Rivets help your product distribute clamping forces, preventing thin sheets or low-strength materials from being locally crushed.
②Mandrel
The mandrel of Hemlock Rivets does not simply break off and become ineffective; instead, it forms a mechanical locking mechanism. Hemlock features a retained stem and an interference lock created by a splined stem. This is a key reason why Hemlock Rivets offer superior vibration resistance compared to standard open-end rivets.
③Large Blind Side Bearing Area
Hemlock Rivets create a larger bearing area on the back side of the material. This distributes the tail load and clamping force, reducing the risk of creep, deformation, or tear-through in thin sheets, plastics, brittle materials, or low-strength materials.
Key Structural Features of Hemlock Rivets
① High shear strength and tensile strength
Hemlock Rivets provide more consistent connection strength than standard hollow rivets, making them ideal for structural applications. In our RIVMATE practical tests, for example, the carbon steel B-type round-head 6.4mm rivet achieved a tensile strength of 7,920 N and a shear strength ranging from 7,700 to 12,500 N.
②Suitable for vibrating environments
Ideal for products that are constantly exposed to vibration, helping to reduce loosening and rattling at connection points.
③Superior hole-filling capability
Hemlock Rivets reliably fill holes, even if their size or shape varies slightly from the intended specifications.
④More stable mandrel retention
With Hemlock Rivets, the mandrel remains securely in place within the rivet head after riveting is complete. This reduces problems caused by mandrel dislodgement.
How Hemlock Rivets Work
Hemlock Rivets are typically installed using the following process:
- Insert the rivet into the pre-drilled hole
During installation, you only need to work from the front of the workpiece; there is no need to place a nut on the back or perform welding. When inserting the rivet into the pre-drilled hole, ensure that the hole diameter and plate thickness are within the specified range. - The riveting tool pulls the mandrel
The riveting gun pulls the central mandrel, which causes the rivet body to deform, beginning to form a bulge on the blind side. - A large-area support structure forms on the blind side
The tail end of the rivet body gradually deforms and spreads out on the back of the workpiece, forming a large load-bearing surface. - The rivet body expands within the hole to fill the hole walls
The rivet body expands in all directions toward the hole walls, reducing gaps and improving the fit within the hole as well as vibration resistance. - The mandrel breaks and is locked in place
After breaking, the mandrel is secured inside the rivet body, creating a mechanical lock. This reduces the risk of rattling, mandrel loss, and electrical short circuits caused by a loose mandrel.
