The KSRTB4-30J22 is a metric ratchet with a pitch of 12.56 mm and 30 teeth, designed for applications requiring reliable one-way rotation. It is constructed from S45C mild steel and features induction-hardened teeth with a hardness rating of 50 to 60 HRC, ensuring durability and wear resistance. The ratchet has a finished bore diameter of 22 mm and an outside diameter of 90 mm, with a face width of 25 mm. The product is suitable for applications where reverse rotation is not desired, as the pawls are designed to prevent it. It is important to note that due to the heat treatment process, some deformation of the bore may occur, necessitating potential reaming to achieve specified dimensions.

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.
