Product Description
1. Strong and Reliable Hydraulic Cylinder Nut
This is our hydraulic cylinder nut, designed for high-pressure hydraulic systems. Regular nuts can loosen under high pressure. The threads may become damaged, causing oil leaks and equipment downtime. These problems can interrupt your operations and result in costly repairs.
Our hydraulic cylinder nut is designed to prevent these issues. It provides a secure and reliable connection, even in demanding working conditions. You can depend on it for tough applications.

2. Built with a Strong Metal Flow Structure for High Strength
We use a specialized cold-heading machine to manufacture this nut. During the forming process, the metal flow lines remain continuous, which enhances the strength of the finished product.
The nut has a tensile strength of ≥800 MPa and a hardness range of HRC 25–35. This hardness range provides an ideal balance between strength and durability. It is not so hard that it damages the mating screw rod, and it is not so soft that it loses its locking performance. As a result, the nut remains securely fastened while helping protect your equipment.

3. OEM Support and 100% Quality Inspection
We support OEM orders. Simply send us your drawing, and we will manufacture the nut according to your specifications.
Thread sizes are available from M6 to M36, and thread accuracy can be customized to either 6H or 6g standards. Surface treatment options include phosphating, zinc plating, and blackening.
We perform a 100% inspection on every nut before shipment to ensure consistent quality. The minimum order quantity (MOQ) is 100,000 pieces, and the production lead time is approximately one month. Discounts are available for large-volume orders.
