Structural Rivets
Structural Blind Rivets are designed to fix elements where a high resistance to both tensile and shear strengths are required
The High Strength Blind Rivet is versatile and especially designed for safety. It not only provides secure hold, but also takes on a load-bearing function.
Structural Rivets exceptionally strong once set. The high strength is as a result of the mechanically locked stem. The locking occurs during the riveting process when the mandrel has traveled the full length of the rivet body. The strength comes from the mandrel being locked in place and completely filling the space along the shear plane from the primary through to the secondary side of the head.
When set properly, this results in a flush break, where the mandrel is broken nearly even with the head. Structural Rivets are primarily used in the transportation industries like Truck, Trailer, RV and Locomotive, however it is often used commercially as well.
High Strength Blind Rivets with Conical Closing Head
High Strength Blind Rivets with conical mandrel head provide extra vibration-resistance and a highly strong connection between the elements of varying thicknesses. Solid hole bearing helps to adjust the pre-drilled hole tolerances without any problems. With the proper pre-drilled hole tolerances, these high strength rivets can be watertight. During the setting process, the mandrel head is mechanically locked inside the snap head and the mandrel breaks with the head. The remaining mandrel is retained within the rivet body which allows very high shear and tensile values of these rivets. They are ideal for applications with heavy loads.
Examples of this type are GO-LOCK and M-LOCK
GO-LOCK
The GO-LOCK rivets offer high strength, extensive grip range, and excellent clamp-up force. High Strength Blind Rivets GO-LOCK possess multiple grip range applications.
This system provides a mechanical lock that delivers 100% mandrel retention. The mandrel also fills the body of the rivet to give greater shear strength.
Their outstanding drill hole filling allows adjusting the hole tolerances without any diffi culty. Locking of the remaining mandrel in a GO-LOCK is carried out mechanically with help of a special integrated locking system. Working with these rivets does not require any special riveting equipment.

High Strength Rivets with Toric Closing Head – GO-BULB
In general, High Strength Blind Rivets with toric mandrel heads are renowned for being especially practical when fixing thin walled components. During the setting process, these rivets build a large closing head that ensures high strength and safe connection between elements.
The GO-BULB H-LOCK are examples of this type.
GO-BULB/GO-INOX
High strength steel break-stem fasteners with excellent bulbing tail formation. Ideal for thin sheet materials.
The Go-Bulb also has the advantage of good hole fill compensating for irregular, oversized, or misaligned holes.

H-LOCK Structural Rivet
This rivet also expands under the closing head during setting and creates an extremely powerful grip. Grooved mandrel ensures safe locking between the elements without making the clapping sound. With a properly prepared drill hole, this rivet is also splash-proof.
Characteristics
• suitable for high loads
• expands under the closing head to give more grip
• the mandrel head is held captive within rivet body (mechanical mandrel locking)
• the riveting is splash proof
• high shearing and tensile forces
• extremely suitable for thin sheet material.

Material Usage Guide
Galvanic Corrosion • When dissimilar metals come into contact in the presence of an electrolyte, a galvanic action occurs which corrodes one metal at a faster rate and the other more slowly. This phenomenon can cause major riveted joint failures and care must be taken to avoid the occurrence. The following table is a guide.
| METAL JOINED | |||||
| RIVET MATERIAL↓ | Aluminium | Coated Steel | Stainless Steel | Copper | Brass |
| Aluminium | YES | CARE | NO | NO | NO |
| Coated Steel | NO | YES | NO | NO | NO |

Hence,
1) Select materials that are as close together as possible in the Galvanic Series Chart
2) Provide a barrier between the two metals, such as paint, non-metallic washer or gaskets
3) Design the fastener as the cathode so the cathodic area is small as compared to the anodic area
4) Use a metallic finish on the fastener that is close on the chart to the mating material
