Types of Spanner
Combination spanner: The combination spanner is a versatile tool that features an open end on one side or both sides. Its design allows for both quick turning with the open-end and higher torque application with the closed-end.
Double ring spanner: As the name suggests, the double-ring spanner has two closed ends (rings) of different sizes. This design allows for a better grip on nuts and bolts, reducing the chances of slipping.
Gas spanner: The gas spanner is specifically designed for use with gas cylinders. Its unique shape and size allow for easy fitting and removal of gas cylinder valves. The gas spanner is lightweight, compact, and provides a secure grip.
Single open end spanner: The single open-end spanner features a single open end, allowing for quick turning of nuts and bolts. It is lightweight, easy to handle, and suitable for tight spaces.

Features of Spanner
Ratcheting mechanism
Based on a gear and pawl assembly, it provides reversible, unidirectional motion. A direction selector switch allows users to switch between tightening mode and loosening mode.
Durability
Strengthened heads and precision-machined parts can resist high torque.
Size range
Offers metric and imperial sizes, fixed jaws or jaws that can be adjusted.
Tools that are used to loosen, put nuts and bolts in place and tighten are called as spanners. Spanners have a shaped opening, opening for turning a nut or bolt or jaws for gripping. These tools are used in a number of places and hence require a high quality raw material for a long lasting life. To match the needs of all, spanners and wrenches come in various shapes and sizes. Wrenches are used to nut small bolts and at the same time big machines. They are made in a way that works for each. These tools should have properties like durability and hardness. They are used in industries, factories, garages and homes.
Production Process of Spanner
Forging: It is made by heating high-grade steel (typically chrome vanadium steel)and forging it through drop forging hammer to form the basic frame.
Machining: Spanner dimensions are made by cnc machines, providing accurate tolerances for both the ends.
Heat treatment: The spanners is strengthened for toughness by being hardened, followed by tempering to counter brittleness.
Surface finishing: Chrome plating or electroplating contributes corrosion resistance as well as a smooth finish. Quality control: Each process is strictly controlled for compliance with standards such as din 3113. They are normally manufactured beyond the din 3113 standard specifications.
