[Technical Information] Basic Knowledge of Screws: "Textbook on Screws Learning from the Basics"
Textbook Series on Screws Learned from the Basics
The textbook on screws created by a group of screw specialists, 'Learning About Screws from the Basics.' You can understand fundamental knowledge from types of screws to fastening design. Available for free!
Daiichi Kogyo is a specialized group that develops and manufactures both bolts and nuts. Although they are both "fasteners," bolts and nuts differ in materials, processing methods, manufacturing equipment, and required performance. 【What a specialized group can do】 ● Consideration of optimal materials and shapes: The "development/design capability" of a specialized group → Utilization of FEM analysis and knowledge of materials ● Evaluation and analysis of fasteners with data backup: The "evaluation capability" of a specialized group → Performance evaluation from individual parts to actual machines ● Reduction of prototype lead time and mass production: The "production technology/manufacturing technology capability" of a specialized group → In-house mold production and utilization of FEM analysis For more details, please visit the 【Daiichi Kogyo Co., Ltd. Fastener Division Fastening Parts Site】 below. "Useful information about fasteners" is also available. Please take a look. There is a "Textbook on Fasteners: Learning from the Basics" created by a specialized group in fasteners. - What are fasteners - The mechanism of how fasteners tighten - Fastener loosening - Fastener design You can understand the basic knowledge of fasteners.
