Blind nut "RIVKLE" easy and stable assembly

Blind nut "RIVKLE" easy and stable assembly

Unable to assemble welding nuts... Ideal for such work! Blind nuts that enable the production of nuts and bolts. *Performance data available.

The product we handle, "Ribclay," is a load management type blind nut. It can be assembled onto thin iron plates, aluminum, magnesium, CFRP, PP, and foam molded products. Unlike welding nuts, it does not generate heat during assembly, preventing damage to surface treatments and minimizing harm to the workpiece. Additionally, the absence of heat generation prevents the release of harmful gases due to combustion. If you consult with us, we can recommend suitable part numbers from over 3,200 options based on your workpiece! Of course, we can also develop products tailored to your needs. **Features of Ribclay** - Can be assembled onto thin plates and materials other than iron, where welding nuts are unsuitable - Allows assembly from one direction - Can be assembled at any stage, whether before or after painting the workpiece - No thermal stress on the workpiece *For more details, please refer to our catalog and performance materials in PDF format, or feel free to contact us.*

Blind nuts for CFRP, Ribbed Clere SFC, crack prevention & easy assembly

Blind nuts for CFRP, Ribbed Clere SFC, crack prevention & easy assembly

RIVKLE SFC was developed to assemble resistant threads without damaging plastics or composite materials.

SFC was developed to create resistant threads without damaging plastics or composite materials. It is designed to prevent resin from cracking when installed on resins that are most susceptible to cracking. 【Features】 The resin does not crack because it does not put stress on the edges of the product hole. Since it does not apply stress to the edges of the product hole, it does not cause delamination in CFRP. It can accommodate hole tolerances from +0.1 to +0.6, so it does not require strict hole machining precision. It can be adapted to machining locations closer to the ends. (PA66: 4.5 mm) It can also accommodate materials other than CFRP, such as EPOXY CARBON, PP6.6, SMC, and PP.

Sealing blind nut for battery tray, compliant with IPX7.

Sealing blind nut for battery tray, compliant with IPX7.

The O-ring is pre-assembled to the part, so a sealing washer and bag nut are not required, ensuring water tightness.

In general, standard blind nuts do not ensure water tightness. The ribbed sealing ring complies with IPX7, making it ideal for use in battery trays where water tightness is required. Even with an O-ring, it supports: - Automatic feeders - Resistance from -35 to 220 degrees - Resistance to aging and liquids - High rust prevention performance - Compliance with ATEQ, IPX7, and ISO20653 Amid the global shift towards electric vehicles, we have received many inquiries regarding battery trays.
