11/21/2023 0 Comments Crossbow boltThe fletching is typically made from soft light materials such as feathers, plastic or silicone rubber. The weight of a shaft is usually in grains, and product descriptions may provide the total weight in grains, or in grains per inch (GPI), for which the total weight of shaft can be calculated by multiplying the GPI value with length of shaft in inches.įletchings, also referred to as vanes, are fins located at the rear end of the shaft just before the nock. The more resistant to bending a bolt is, the more "spine" it is said to have, and a crossbow with higher draw weight ideally needs to be paired with a heavier bolt point and higher spine specifications. Shafts come with varying degrees of stiffness - referred to as the " spine" of the bolt. In modern times it is normally made of carbon fibre or aluminium alloy (or sometimes both aluminum and carbon fibre are used), and is very lightweight for its strength. The shaft is the main body of the bolt to which other parts of the bolt are attached. The point, also called the head or the tip, is the pointed and weighted front end of the bolt, which is sharp and hard so that it can penetrate the target.
