Iwaki, Japan – July, 2025 – Tungaloy Corporation (President: Satoshi Kinoshita, Head Office: Iwaki City, Fukushima Prefecture) announces the launch of its SolidFixWrench, a high-precision hand tool for screw fastening operations. Designed with high durability for Torx Plus screw applications, the tool will be available nationwide.
Challenges and Trends
The tightening of screws during insert replacement is a critical process that directly affects machining stability. However, due to differences in operator skill levels and the accuracy of the tools used, the proper torque may not always be applied.
In particular, when the contact precision between the wrench and the screw is low, it can lead to issues such as “stripping”—damage to the screw socket—or insufficient tightening torque, which may cause insert dislodgment or breakage.
These problems can result in reduced productivity and unexpected line stoppages, posing serious challenges. Ensuring secure screw tightening is essential for stabilizing production.
Product Overview
SolidFixWrench is a high-precision wrench series designed to improve screw fastening operations.
Its high-precision and high-quality construction enables easy and reliable tightening, significantly enhancing both the efficiency and repeatability of insert change operations.
Benefits and Features
Feature 1: Stable Tightening Accuracy with High-Precision Tip Design
– Utilizes a high-precision tip profile that minimizes clearance with the screw socket
– Ensures a secure fit to the screw head, preventing cam-out (stripping) and reducing operational errors
Feature 2: Reliable Torque Transmission and Improved Workability
– High-rigidity shaft design enables efficient and loss-free torque transmission
– Ergonomically designed grip prevents excessive force and ensures stable handling
Feature 3: High Durability That Resists Deformation Even with Repeated Use
– High-strength tip prevents deformation even after repeated use, maintaining precision over time
– Offers more than twice the durability of conventional products
