Generally, the bolts are 15 to 22 inches long but the standard length is 20 inches. Experts recommend longer bolts [4] but they have certain disadvantages as well. The weight of the bolt can have a serious effect on the range of the bolt. The bolt's total weight includes the bolt's weight, nock, insert, vanes, and broadhead or field point.
21st-century hunting compound crossbow. A crossbow is a ranged weapon using an elastic launching device consisting of a bow-like assembly called a prod, mounted horizontally on a main frame called a tiller, which is hand-held in a similar fashion to the stock of a long gun. Crossbows shoot arrow-like projectiles called bolts or quarrels.
The Thury thread form had the crests rounded at 1 / 6 p and the roots rounded at 1 / 5 p so the thread angle was close to 47.5° but not exactly. This was simplified in the BA thread definition by defining the thread angle to be 47.5° exactly and the thread form to be symmetrical with a depth of 3 / 5 p .
The thread form is slightly modified to increase the minor diameter, and thus the strength of screws and taps. The major diameter still extends to within 1 / 8 H of the theoretical sharp V , but the total depth of the thread is reduced 4% from 5 / 8 H = 5 / 8 cos(30°) P ≈ 0.541 P to 0.52 P . [ 5 ]
The sharp bolts of the crossbow did more damage than the slow-moving, blunt bullets of the bullet-shooting crossbow. [6] Because the standard bolt does more damage, the bullet-shooting crossbow was reserved for hunting smaller animals. There was no reason to use a bolt-shooting crossbow to hunt squirrels when a smaller, less-powerful weapon ...

The arbalest (also arblast), a variation of the crossbow, came into use in Europe around the 12th century. [1] The arbalest was a large weapon with a steel prod, or bow assembly. Since the arbalest was much larger than earlier crossbows, and because of the greater tensile strength of steel, it had a greater force.
