FAQS on threaded hex nut

Q: What is a threaded hex nut used for?

A: A threaded hex nut is designed to fasten onto a bolt or screw with matching threads, providing secure mechanical locking. Its hexagonal shape allows easy tightening using wrenches or sockets. Common in construction, automotive, and machinery applications.

Q: What does "5/16-18 hex nut" mean?

A: The term "5/16-18 hex nut" refers to a hexagonal nut with a 5/16-inch diameter and 18 threads per inch (UNC thread standard). This size is commonly used in medium-duty fastening applications. The 18 TPI ensures a finer grip for secure assembly.

Q: How does a 4 hex nut differ from standard hex nuts?

A: A "4 hex nut" typically denotes a metric M4 size nut with a 7mm hexagonal width. It’s smaller than imperial-sized nuts like 5/16 and suits lightweight applications such as electronics or furniture. Always verify thread pitch (e.g., M4x0.7) for compatibility.

Q: Are threaded hex nuts reusable?

A: Yes, threaded hex nuts can be reused if threads remain undamaged and corrosion-free. However, repeated use may wear threads, reducing clamping force. Replace nuts if deformation or thread stripping occurs for safety-critical applications.

Q: Can I mix a 5/16-18 hex nut with a 1/4-20 bolt?

A: No, a 5/16-18 nut (5/16" diameter, 18 TPI) won’t fit a 1/4-20 bolt (1/4" diameter, 20 TPI) due to mismatched size and thread pitch. Always match bolt/nut diameter and threads-per-inch (or pitch) for proper function.
