Question 1

What is the main function of a 2 Way Lock Nut?

Accepted Answer

A 2-way locknut is designed so that it will not loosen under vibration or load stress because it has locking mechanisms at both ends of the nut. This double locking increases torque resistance and helps maintain joint stability in high vibration environments. Unlike standard nuts, 2-way locknuts prevent loosening even in dynamic or rotating systems and are therefore essential for the structural integrity of mechanical assemblies and equipment.

Question 2

What materials are used in manufacturing 2 Way Lock Nuts?

Accepted Answer

Common materials include stainless steel (304 and 316), alloy steel, carbon steel and brass. Stainless steel variants provide corrosion resistance in marine or chemical environments, while carbon and alloy steel options offer high tensile strength and durability in structural or mechanical settings. Surface finishes such as zinc plating, hot-dip galvanizing and black oxide further enhance corrosion resistance and product lifespan.

Question 3

What standards do 2 Way Lock Nuts comply with?

Accepted Answer

2-way locknuts generally comply with standards such as ASTM A194 (high pressure/high temperature applications), DIN 980 (mechanical locknuts) and ISO 7042 (all-metal nuts with prevailing torque). These standards ensure dimensional accuracy, thread integrity and mechanical performance. Adherence to these standards is necessary for application within regulated industries like transport, energy and aerospace.
