FKD Precision Lock Nuts

FKN/FKNA

Manufactured domestically since 1985 under a license agreement between Gewinde Ziegler AG (Switzerland) and Fukuda Trading Co., Ltd., FKD precision lock nuts are a proprietary brand product.

All FKD brand nuts are produced under management systems based on ISO9001/ISO14001. With advancements in machining technology, components such as bearings, shafts, and housings require high-precision nuts to ensure accurate assembly and function.

Simultaneously machining the thread and end face of high-precision nuts minimizes assembly adjustment time and maintains high rotational accuracy of the shaft.

Comparison of the end faces of ground nuts and turned nuts

Polished nuts have a small surface roughness, which improves the contact (degree of adhesion) between the end face and thread surface. They are highly effective in precision applications.

Details of the ZM series

Features
We simultaneously polish the nut thread surface and end surface, controlling the precision lock nut for squareness.
We control the effective diameter of the ZMN nut even more strictly than ISO 4H standards. We also polish the outer diameter and machine-tapped holes to ensure parallelism control and dynamic balancing after installation.		 ZM type 180° x 2 set screws are fixed from the circumferential direction.
60° x 2 high retention type is also available. (ZM-S)
ZMV type 180° x 2 set screws are fixed from the axial direction.
60° x 2 high retention type is also available. (ZMV-S)
Main Applications ZMT type 120° x 3 set screws are fixed from the circumferential direction.
● Bearings for machine tool spindles
● Nuts for fixing ball screw support bearings
● Nuts that require precision
● Areas where you want to reduce adjustment time		 ZMN type 120° x 3 set screws for axial fixing.
30° x 12 balance tap holes.
60° x 6 axial and circumferential clamping pin holes.
Screw precision detail
● ISO standard 4H grade
● Shaft thread 4h recommended
Material: SCM435
Hardness: M85 x 2.0 or less HRC30-37
