The NEMA14 captive stepper motor you mentioned is designed with a lead screw and has a holding torque of 0.2kg. The lead screw has a TR5*4(p1) specification. Here are the details:

Motor Type: 2-phase stepper motor
Holding Torque: 0.2kg (kilograms)
Lead Screw: TR5*4(p1)

The holding torque of 0.2kg indicates the maximum torque the motor can generate to prevent rotation or hold a load in place. Holding torque is typically measured in N.m (Newton-meters) or kg.cm (kilogram-centimeters).

The lead screw specification TR5*4(p1) refers to the thread type, pitch, and additional characteristics of the lead screw. TR5 indicates a trapezoidal thread profile with a 5mm major diameter. The "*4" indicates a pitch of 4mm, meaning the lead screw advances by 4mm for each complete revolution. The "(p1)" suggests that the lead screw may have specific properties or modifications, which can vary depending on the manufacturer or specific application requirements.

This type of stepper motor with a captive lead screw is commonly used in automation machines, such as automated assembly systems, precision positioning systems, or other applications that require controlled linear motion.
