Pull methods

The "pull method" comprises Spin on, 1. Insert, 2—upset, 3. and Spinoff, 4. cycles.

Selection criteria for blind rivet nut Selecting the body.

Hexagonal body A hexagonal body in a hexagonal hole ensures the blind rivet nut has the best resistance to over-torque turning.
Round body, knurled or plain For use where a hexagonal hole is not possible. The knurled version is preferred to the smooth, particularly for plastic or soft materials (aluminum, PA, SMC, etc.).
Open-end This is the most common option due to its compact form and the free choice of screw length.
Closed-end For all uses where no liquid is to be allowed to pass between the screw and the blind rivet nut. To form a pressure-tight seal between the blind rivet nut and the workpiece, we manufacture blind rivet nuts with a seal on the bodyside (see example on page 112).
Hexagonal body, flat head "Advantages: 1. Very high turning resistance 2. Suitable for soft components (aluminum, plastic,...) 3. High crimping force 4. screw length can be varied (open end) 5. Splash-proof closed-ended)"

Selecting blind rivet nuts and studs to suit your component

Measure the thickness of the parent material. Check that this thickness is within the grip range (minimum–maximum).

If you have a choice between 2 blind rivet nuts in the allowable tolerance range, Select the shorter if the workpiece is complex. A relatively wide upset area is required for plastic workpieces and soft parent materials (aluminum) to achieve high mechanical strength. Please get in touch with us about this.

Selecting the material

Standard are supplied in steel, aluminum, and stainless steel. The choice of material depends on the strength of the blind rivet nut and stud (see table page 89 and the required corrosion resistance of the completed end product. Our standard products manufactured from stainless steel are suitable for use in some catering and food processing industries. We would be pleased to provide further information on stainless steel or brass blind rivet nuts or corrosion resistance.

Blind rivet nuts with slotted shank for ultimate pull-out force values

Blind rivet nuts with slotted shanks for ultimate pull-out force values have been specially designed for integrating into plastic parts, hollow sections, or thin-walled sheet steel requiring high pull-out forces. The slotted shank splays into four "petals" on the blind side of the base material, thus offering a large bearing surface and ensuring maximum pull-out force. Ultimate pull-out force。Advantages: Large clamping area for higher pull-out resistance (soft and thin materials)， Large bearing surface to reinforce the workpiece， Minimal radial stresses during installation to reduce the risk of breakage in weak materials， Available in steel (aluminum and stainless steel on request) in thread sizes M4 to M10

Waterproof， Coating and heating 150°C

"Advantages:

1. Integrated sealing function

2. Pre-applied seal

3. Stable tensile strength in the mating screw."

The Seal Ring technology features a captive sealing ring for simple and reliable installation, even during automatic blow-feed installation. The robust assembly creates a sealed fastening point that meets the requirements of ISO 20653 and automotive quality—tightness in all circumstances. Preserve your assemblies from external influences. This insert leaves no room for compromise and ensures sealing against fluids while retaining overtime performance (metal-to-metal contact). All our products are proof-tested with air pressure by a stringent process and comply with the highest demands from the automotive industry. Electronic power battery is a vital part of Electric Vehicles. The battery pack and the battery cell leakage test influence the battery systems' and electric vehicles' safety. The battery pack and cell leakage test affect the safety of the battery systems and electric cars. According to the leakage test, IP67 requires a leak test, Electric Vehicles, battery pack or battery cell, and seal.
