Product Description
Product Overview
This product is a stainless steel floating nut, manufactured from 303 stainless steel material with a performance grade of 8 and passivated surface treatment. Its design consists of a nut body and a floating bushing (or elastic component), allowing the nut to make micro-displacements within a limited radial or axial range. This floating amount can compensate for deviations caused by machining errors, thermal expansion or misalignment during assembly, thereby achieving stress-free precise alignment and reliable fastening. It is especially suitable for rigid connection structures that require high-precision assembly.
Core Advantages
-
Automatic Deviation Compensation: The unique floating structure can absorb alignment errors during assembly and eliminate assembly stress caused by forced alignment.
-
Improve Assembly Yield: Effectively solve the problem of difficult bolt penetration or tightening caused by hole position deviation, and improve production efficiency.
-
Reliable and Durable Connection: High-strength 303 stainless steel and Grade 8 performance ensure long-term reliability of the fastening point, and passivation treatment enhances corrosion resistance.
-
Protect Connected Components: Avoid thread wear, base material deformation or preload inaccuracy caused by forced alignment.

Warm Tips
-
During installation, ensure that the floating nut is correctly pressed or installed into the base plate hole, and check whether its floating range matches the design.
-
Before completing the final tightening, it is recommended to pre-tighten the bolt first, use the floating amount for natural centering, and then tighten it to the specified torque in sequence.
-
Do not weld or reprocess the floating nut, so as not to damage its floating structure and performance.
