FAQS on 7 8 hex nut
Q: What is the difference between a 7/8 hex nut and a 10mm hex nut?
A: The main difference is the measurement system. A 7/8 hex nut uses imperial units (≈22.23mm), while a 10mm hex nut follows the metric system. Always verify the required unit system for your project to ensure compatibility.
Q: Can a 7/16 hex nut be used interchangeably with a 7/8 hex nut?
A: No, their sizes are vastly different. A 7/16 hex nut has a 11.11mm width, whereas a 7/8 hex nut is ≈22.23mm. Using the wrong size can compromise structural integrity.
Q: What does "1/2-20" mean in a 1/2-20 hex nut specification?
A: "1/2-20" refers to the thread size: 1/2-inch diameter with 20 threads per inch. This standardized notation ensures compatibility with matching bolts. Always confirm thread pitch before purchasing.
Q: Are 10mm hex nuts suitable for automotive applications?
A: Yes, 10mm hex nuts are commonly used in automotive assemblies due to their metric sizing. Ensure they meet the required strength grade (e.g., Grade 8) for high-stress environments.
Q: How do I choose between a 7/8 hex nut and a 7/16 hex nut for plumbing?
A: Check the bolt or pipe thread size. A 7/8 hex nut fits larger-diameter bolts (≈22mm), while a 7/16 suits smaller ones (≈11mm). Material (e.g., stainless steel) also impacts corrosion resistance.
