The KSRTB4-50J40 is a metric ratchet with a pitch of 12.56 mm and features 50 teeth. It is constructed from S45C mild steel and has undergone induction hardening, resulting in a tooth hardness of 50 to 60 HRC. The ratchet has a finished bore diameter of 40 mm and is designed to prevent reverse rotation, making it suitable for applications where back-driving is not desired. The product's specifications indicate that it is not intended for use as a driving ratchet. Additionally, due to the heat treatment process, some deformation of the bore may occur, necessitating reaming to achieve the specified dimensions. The allowable torque ratings and shear strength of keyways are also provided, which can assist engineers in determining its suitability for specific applications.

Industrial fasteners are hardware devices that join two or more items together, creating a semi-permanent or permanent connection. The fasteners most frequently used by machinery designers are screws, nuts, retaining rings, and various types of pins because of the basic role that they play in the assembly of mechanisms. Various industrial hardware components are used in the assembly process including knobs, washers, spacers, shims, handles, springs, spring-powered reels, and ball plunger screws.
Fasteners play a vital role in a wide range of applications, from everyday household items to medical devices, robotics, and even outer space. Careful consideration must be given before selecting the most appropriate fastener for an application.
