Nuts & Lock Nuts
Hex, flange, nylon-insert and all-metal lock nuts, quoted on thread, property class and across-flats. A lock nut is picked by how it resists loosening, not by whether it has a nylon ring: nylon-insert nuts are reusable a few times at moderate temperature, all-metal nuts take heat and vibration but are not meant to be reused.

What decides the price
In order of impactNylon insert, all-metal deformed thread or a serrated flange. Each one solves a different problem and each one has a temperature limit.
A class 8 nut on a 12.9 screw is the weak link. Nut class is matched to the screw, not chosen by price.
Standard, thin and heavy patterns share a thread and differ in what they fit. Thin nuts go where a standard height does not clear.
Worth checking before you order
The insert takes a set. After a few cycles it holds like a plain nut, and nobody notices until it does not.
The assembly fails at the nut. Matching the class costs very little and is the whole point of specifying one.

Questions
Which lock nut works at high temperature?+
All-metal. The nylon insert has a working temperature limit and above it the nut stops locking.
Can you match nut class to my screw class?+
Yes. Tell us the screw class and we quote the matching nut class rather than the cheapest one on the list.
Send the specification, not the product name.
Grade, size, thread standard and coating are what a quote is built from. A product name alone produces a price that changes twice before the order.
