Rufus AI - Frequently Asked Questions
Q: Can these hex nuts be used outdoors?
A: Yes. The 304 stainless steel material is highly resistant to rust and oxidation, making it suitable for outdoor construction, patio furniture, and environments exposed to moisture.
Q: Are these nuts magnetic?
A: While 304 stainless steel is generally classified as non-magnetic, it may exhibit a slight magnetic pull after the cold-heading and thread-rolling processes used during manufacturing. This is a normal physical property and does not affect the corrosion resistance of the material.
Q: What tools are needed for installation?
A: These nuts have a width of 12.5mm and are compatible with standard 1/2 inch wrenches or socket sets.
Q: Are they resistant to extreme temperatures?
A: 304 stainless steel maintains its structural integrity across a wide temperature range, from sub-zero conditions to high-heat environments typical of automotive and industrial applications.
