An implement bolt is a strong and durable bolt used to attach implements and accessories to a tractor's 3-point hitch. It helps secure the implement in place during operation and ensures a stable connection between the tractor and the implement.

Implement bolts for 3-point hitches come in different sizes and grades depending on the weight and pulling capacity of the implement. The most common types are Category I, II, and III, which vary in diameter and length. There are also quick-release bolts designed to facilitate fast attachment and detachment of implements without the need for tools.

The choice of an implement bolt depends on the category of your tractor's 3-point hitch and the weight and load of the implement being attached. Make sure to select the correct size and strength grade to prevent the bolt from bending or breaking under stress. Also, check that the implement bolt is compatible with your tractor’s hitch category (such as Category I, II, or III).
