The KSRTB1-90 is a 3.14 mm pitch, 90-tooth ratchet with an induction-hardened tooth surface (50-60 HRC) made from S45C steel, designed to prevent reverse rotation. It has a 50 mm bore, 90 mm outside diameter, a 50 mm hub width, and a total length of 90 mm. The allowable torque is 34.5 N·m (3.52 kgf·m), and the weight is 0.73 kg. The pawl assembly is not suitable for driving torque. Due to heat treatment, bore deformation may occur, requiring reaming. Secondary operations on tooth areas are not permitted.

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.
