Q: What are the dimensions of a 1/4 hex nut?

A: A 1/4 hex nut refers to a 1/4-inch nominal size with a 7/16-inch width across the flats. It is commonly used with 1/4-inch bolts or threaded rods. This size adheres to SAE or ANSI standards.

Q: How does a 5/16-18 hex nut differ from an M14 hex nut?

A: A 5/16-18 hex nut is an SAE thread with a 5/16-inch diameter and 18 threads per inch, while an M14 hex nut is metric with a 14mm diameter and a 2mm pitch. The two are not interchangeable due to differing sizing systems.

Q: What applications are M14 hex nuts typically used for?

A: M14 hex nuts are widely used in automotive, machinery, and construction for heavy-duty fastening. Their metric sizing suits international engineering standards. They often pair with M14 bolts for high-strength connections.

Q: Is a 4 hex nut the same as a 1/4 hex nut?

A: No, a "4 hex nut" might refer to a 4 size (approx. 0.112-inch diameter) in machine screw sizes, whereas a 1/4 hex nut is larger (0.25-inch). Always confirm the measurement system (SAE, metric, or screw gauge) to avoid errors.

Q: What wrench size fits a 5/16-18 hex nut?

A: A 5/16-18 hex nut requires a 1/2-inch wrench for the flats. The thread pitch (18 TPI) ensures compatibility with matching bolts. Always use calibrated tools to prevent rounding the edges.
