❓ Frequently Asked Questions (FAQ) About Hex Nuts
Q: What does "A2-70" mean for stainless steel nuts?
A: A2 refers to the material type (304 stainless steel), and 70 indicates the strength class. A2-70 stainless steel nuts have a minimum tensile strength of 700 MPa, making them strong and corrosion-resistant for most general-purpose applications.
Q: What is the difference between "full nuts" and other nut types?
A: Hexagon full nuts (also called finished hex nuts) are standard height nuts that provide full thread engagement. They're different from thin nuts (jam nuts) which are shorter, or flange nuts which have an integrated washer-like base.
Q: Are these metric nuts compatible with SAE/Imperial bolts?
A: No, these are metric thread nuts designed specifically for metric bolts (M3, M4, M5, M6, M8, M10, M12). They will not properly fit SAE/Imperial bolts (like 1/4", 5/16", etc.). Always match nut and bolt thread types.
Q: Can I use these stainless steel nuts with galvanized or regular steel bolts?
A: While possible, mixing dissimilar metals can lead to galvanic corrosion, especially in wet environments. For best results, pair A2 stainless steel nuts with A2 or A4 stainless steel bolts. If using with regular steel bolts, consider using anti-seize compound.
Q: What does DIN934 standard mean?
A: DIN934 is a German industrial standard that specifies dimensions, tolerances, and technical requirements for hexagon nuts. Nuts manufactured to this standard ensure consistent quality and compatibility with tools and fasteners worldwide.
Q: Are these nuts sold individually or in packs?
A: Typically, these metric hex nuts are sold in quantity packs (e.g., 50, 100 pieces). When ordering, you select both the size (M3-M12) and quantity option. Please check the product options carefully before purchasing.
