Automobile engineering is a highly practical branch of applied science where theoretical knowledge alone is not sufficient — hands-on skill is equally vital. For a beginner mechanic or trainee engineer, the very first necessity is a toolbox, which serves as their primary weapon of work.
Each tool in this box is not merely a piece of metal; it is a means through which the learner begins to understand vehicle mechanics, engineering fundamentals, and practical problem-solving.

Spark Plug Wrench (with Handle) – 1 piece.
Essential for removing and fitting spark plugs in engines.
Torque Wrench – 1 piece.
Used to apply a precise amount of torque to a fastener to prevent overtightening or damage.
Socket Wrench Set – 1 complete set.
Includes ratchet, extension bars, breaker bar, and ‘U’ joint. Useful for working in confined spaces.
Box Spanner Set – 1 set.
Ideal for loosening nuts located in deep or recessed positions.
Double-Ended Open-End Spanner Set – 1 set.
A standard tool for most mechanical tasks.
Combination Wrench Set – 1 set.
Combines an open-end wrench on one side and a ring-end on the other for versatile use.

Screwdrivers and Electrical Testers

Screwdriver – 18″, 12″, and 8″ sizes.
Used for tightening or loosening screws of various sizes.
Phillips (Star) Screwdriver – 8″ and 6″ sizes.

Scriber – 1 piece.
For marking lines or points on metal surfaces.

Raw Materials Used in Automobile Workshops

In addition to tools, various raw materials and consumables are required in automobile workshops and factories. These substances are essential for maintenance, lubrication, cleaning, and electrical work.

⚗️ Main Materials and Fluids

Petrol
Diesel
Lubricating Oil (Mobil Oil) – SAE-30, SAE-80
Gear Oil – SAE-90, SAE-110
Grease – SAE-150, 220, 250 (for lubrication)
Kerosene Oil – For cleaning metal parts
Distilled Water – Used in batteries
Sulphuric Acid – For battery electrolyte
Hydraulic and Brake Oil – Used in braking and steering systems
Grinding Paste, Sticks, Sandpaper, Emery Paper – For polishing and finishing
Solder and Flux – For electrical soldering
Various Types of Wires – L.T., H.T., fuse, and enamel wires
Bulbs, Switches, Condensers, C.B. Points – For electrical components
Rubber Hose, Cord, Cork Sheet, Packing Paper – For sealing and insulation
Cleaning Solution, Soap and Soda – For part cleaning and degreasing
Antifreeze Solution – To prevent radiator freezing in cold climates.

‍♂️ Workshop Dress and Safety Regulations

Proper workshop attire is mandatory for anyone working in an automobile workshop. Wearing the correct protective gear not only ensures safety but also enhances efficiency.

✅ Recommended Clothing

Full-sleeved cotton overalls or coveralls
Safety shoes with rubber soles and steel toe caps
Protective goggles
Insulated gloves
Safety helmet or cap

❌ Avoid Wearing

Loose or synthetic clothing
Scarves or dangling jewellery
Open shoes or sandals

Such clothing can easily get caught in machinery and cause serious injury.

The first step to becoming a skilled automobile engineer or mechanic is to know your tools. Every wrench, plier, and screwdriver should feel familiar in your hands. Proper tools not only increase efficiency but also ensure safety and reduce mechanical damage. Therefore, from the very beginning, every trainee should learn the names, functions, and maintenance of all tools thoroughly.

A well-organised, complete, and neatly maintained toolbox is the true identity of a future automobile engineer.
