A2-304 refers to a grade of stainless steel, often called 18/8 stainless steel. It's known for its good corrosion resistance, particularly in general purpose applications, and contains approximately 18% chromium and 8% nickel.
DIN 934 is a German standard that specifies the dimensions and mechanical properties for metric hexagon nuts. Using DIN 934 compliant nuts ensures they will fit correctly with bolts manufactured to corresponding standards.
A2-304 stainless steel offers good corrosion resistance, but prolonged exposure to saltwater can still lead to pitting or staining. For constant marine submersion or highly aggressive saltwater environments, a higher grade stainless steel like A4 (316) might be more suitable.
These nuts have a thread pitch of 1.75mm, which is the standard fine thread for M12 bolts.
Each bag contains 8 full nuts.
Yes, when properly tightened onto a compatible bolt, these nuts provide secure fastening suitable for many load-bearing applications. For extremely critical structural integrity, always consult engineering specifications.
Verify that the bolt is indeed M12 with a 1.75mm thread pitch. Check both the nut and bolt threads for any debris or damage. Clean threads before attempting to thread again.
The bolt's thread may be stripped, or the wrong thread pitch is being used. Ensure the bolt is M12 x 1.75 and that the bolt itself is undamaged and of sufficient length.
While A2-304 stainless steel is highly resistant, prolonged exposure to aggressive chemicals or certain marine environments can cause surface staining. Clean the affected area gently with a soft cloth and mild soap. For severe issues, consider a more specialized stainless steel grade if recurring.
Setup: These nuts are designed for immediate use. Simply thread them onto a compatible M12 x 1.75 bolt until the desired tightness is achieved. Use an appropriate wrench or socket set to tighten securely.
Compatibility: Ensure that the bolts you are using are also M12 size with a 1.75mm thread pitch to guarantee a proper fit and maximum holding power. These nuts conform to the DIN 934 standard, which is widely recognized for metric fasteners.
Care: While A2-304 stainless steel offers excellent corrosion resistance, regular inspection is recommended, especially in harsh environments. To clean, use a damp cloth. Avoid abrasive cleaners that could scratch the surface. For long-term storage, keep them in a dry place.
