WebbFeatures: Uses a dual screw lock mechanism on one end to secure the cable connection. Compliant with USB 3.2 Gen 1 specifications with up to 5Gbps data speeds. Can carry 3A maximum power to devices from an appropriate power source. Versatile application use. Can be used with non-screw lock devices. Available in 1.5ft., 3ft., and 6ft. variations. A screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside. The screw passes through a hole in another object or medium, with threads on the inside of the hole that m…

WebbA screw is a mechanism that converts rotational motion to linear motion, and a torque (rotational force) to a linear force. [1] It is one of the six classical simple machines. The most common form consists of a cylindrical shaft with helical grooves or ridges called threads around the outside. WebbOne of the more common designs splits the gear into two gears, each half the thickness of the original. One half of the gear is fixed to its shaft while the other half of the gear is allowed to turn on the shaft, but pre-loaded in rotation by small coil springs that rotate the free gear relative to the fixed gear.
