Ratchet wrenches

Ratchet wrenches are a 2-sided variety of open-end wrenches equipped with ratchet lugs. These tools are used for tightening or loosening hex drive screw connections with a wide range of dimensions. They are particularly suitable for work in hard-to-reach places.

Ratchet wrench design

Ratchet wrenches, unlike most types of wrenches, are not uniform in material. They consist of 2 working parts, either a ratchet jaw and eyelet or two ratchet eyelets and a handle in between. These tools have either a forged body or a body consisting of two parallel profiles made of hard steel sheet which are connected in the same shape. In the case of ratchet ring wrenches having a forged body, the jaws are set at an angle of 15° to the axis of the wrench and the lugs are angled at the same angle (15°) to the flat of the wrench. On the other hand, in the case of double-ended ratchet ring wrenches with forged bodies, both lugs are not angled towards the surface of the wrench. The situation is slightly different with 2-way ratchet ring wrenches with sheet metal bodies. There are two versions: with offset and non offset lugs. A very important type of ratchet wrenches are ratchet ring wrenches with a tilting ratchet. In such tools, the ring is hinged to the handle of the wrench by means of a pin. It can be tilted from its flat surface to both sides by an angle of ±90° (=180°).

Currently, the internal profile of the ratchet eyelets is either 6-point or 12-point. Both profiles can be modified to increase the life of the wrench and the nut and bolt head. The ratchets used in these wrenches are 1- or 2-way with a minimum working angle of 5°. The direction of rotation of a single-acting ratchet can be changed by rotating the tool through 180° on its axis, while a double-acting ratchet can be operated by means of a switch. Two-way ratchets are used in 2-way combination wrenches, S-handle ring wrenches and 2-way combination 4-handle ring wrenches, among others. The two ratchets of these 4-sided wrenches have a different size on each of the two sides, e.g. 4/5 mm and 6/7 mm.

Forged body ratchet wrenches are manufactured from chrome vanadium (CrV) steel using forging, heat treatment and machining technologies. The manufacturing standards are defined by ISO 3318 and DIN 3113 and the ratchet wrenches are dimensioned according to metric and imperial systems. Forged tools have a satin chrome or chrome-plated and polished finish, and forged tools have a satin chrome-plated finish. This makes them well protected against corrosion and pleasant to the hand.

Ratchet wrench types

Ratchet wrenches are available in two basic 2-way versions: combination ratchet and ring ratchet. Important sub-types are offset ratchet combination wrenches, S-shaped handles and universal 4-size ratchet wrenches.

Main characteristics of ratchet wrenches

The technical parameters that characterise ratchet wrenches are: size (jaw width, inner ring diameter, mm or inches), outer ring diameter (mm), overall length (mm), working head thickness (mm), working head height and overall weight (g).

Applications for ratchet wrenches

Ratchet wrenches are used in industry (e.g. vehicle and machine assembly plants), industrial services (maintenance departments), construction and handicrafts, service and mechanical workshops, including automotive service. They are manufactured by e.g. Bahco, Beta, Facom, Gedore, Hazet, Proxxon, Snap-on, Stanley, Stahlwille etc.
