定义
Locking nuts are precision-engineered fasteners that incorporate features such as nylon inserts, deformed threads, or prevailing torque designs to maintain clamping force and resist self-loosening in mechanical assemblies. They are critical components in locking devices where secure fastening is essential for safety and operational reliability.
工作原理
Locking nuts work by creating a mechanical interference or friction that resists rotational forces. Common mechanisms include: nylon inserts that deform against threads, all-metal designs with distorted threads that increase thread engagement friction, and two-piece nuts with integrated locking elements that apply counter-torque.
材料
Typically manufactured from carbon steel (grade 58)alloy steelstainless steel (304316)or brass. Nylon inserts are made from polyamide (PA66). Surface treatments include zinc platinghot-dip galvanizingor dichromate coating for corrosion resistance.

常见问题

What is the difference between nylon insert and all-metal locking nuts?

Nylon insert nuts use a polymer ring that deforms against threads for locking, suitable for moderate temperatures. All-metal nuts have distorted threads or integrated locking features, offering higher temperature resistance and reusability.

How many times can locking nuts be reused?

Nylon insert nuts are typically limited to 5-10 reuses before the insert wears out. All-metal locking nuts can often be reused more times if torque values are maintained, but manufacturer specifications should always be followed.
