Discussion Overview
The discussion revolves around the compatibility of stainless steel bolts with anodised aluminium clamps, particularly in a marine environment. Participants explore concerns regarding corrosion, torque specifications for fastening, and the appropriate materials to use in such applications.
Discussion Character
- Technical explanation
- Debate/contested
- Experimental/applied
Main Points Raised
- One participant questions the suitability of using stainless steel bolts in anodised aluminium due to potential corrosion issues, particularly in marine environments.
- Another participant asks for clarification on the type of anodised aluminium clamp and its threading configuration to provide more tailored advice.
- It is suggested to use silicon grease and anti-galling compounds at dissimilar metal contacts to mitigate corrosion risks.
- Participants inquire about the specific grade of stainless steel used for the M10 bolts, noting that different grades may have varying corrosion resistance.
- There is a discussion about the necessity of using stainless steel thread inserts when steel bolts are threaded into aluminium to protect the aluminium from damage.
- Participants express uncertainty regarding the appropriate torque specifications for the bolts and screws, indicating a need for further information on this topic.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the best practices for using stainless steel bolts with anodised aluminium. Multiple viewpoints regarding materials and torque specifications remain unresolved.
Contextual Notes
The discussion highlights the importance of identifying the specific stainless steel grade and the environmental conditions (marine vs. fresh water) that may affect corrosion. There are also unresolved questions regarding torque values and the implications of using different materials in contact.
