Set of keys 108 items: a complete guide to selection and use in

What is a 108-piece key set and who needs it?

Set of keys for 108 items is a universal set of tools that combines all the necessary types of keys for car repair, household appliances and furniture. This set is suitable for both professional mechanics and car owners who prefer to service the car themselves. Unlike minimalistic 20-40 piece sets, the 108 piece set covers 90% of typical tasks: from replacing spark plugs to repairing suspension or dismantling interior panels.

The main advantage of this set is balance between completeness and compactness. It does not take up much space in the garage (unlike professional stands with 300+ tools), but at the same time it contains all popular sizes of open-end, box, and socket wrenches, as well as accessories. For example, the standard kit usually includes:

• 🔧 Open-end wrenches (from 6 to 24 mm)
• 🔩 Spanners (with 12 point socket for better grip)
• 🔨 Socket heads (including deep ones for working with long bolts)
• 🔗 Extensions and adapters (for accessing hard-to-reach fasteners)
• ⚙️ Auxiliary Tools: ratchet handles, cardan joints, adapters for spark plug wrenches

This set is especially relevant for car owners domestic brands (VAZ, GAZ, UAZ) and middle class foreign cars (Toyota, Hyundai, Kia, Renault), where most fasteners are standardized to metric sizes. However, before purchasing, it is important to check whether the package includes wrenches for working with the brake system (for example, 10 and 11 mm for calipers) - they are often missed in budget sets.

Set contents: what should be included in a 108-piece set?

A quality 108-piece set is not just a collection of random keys, but a well-thought-out system of tools. Ideally it should cover three main categories:

1. Basic keys for everyday tasks (changing oil, filters, wheels).
2. Specialized keys for repair of suspension, brakes, engine.
3. Adapters and Accessories for working in cramped conditions.

Let's look at a typical composition using the example of a set from Jonnesway (one of the market leaders in the price-quality segment):

Tool type	Quantity (pcs.)	Dimensions (mm)	Application
Open-end wrenches	13	6–24	Unscrewing nuts in exposed areas (e.g. battery mount)
Spanners (12-point)	13	8–22	Working with “stuck” nuts (less risk of edges breaking)
Sockets (standard)	19	4–24	Removing wheels and suspension mounts
Sockets (deep)	9	8–19	Working with long bolts (e.g. starter mount)
Extensions and adapters	5	75–150 mm	Access to hidden fastenings (e.g. in the engine compartment)

Please note: in cheap sets (for example, from Neiko or Performance Tool) often save on material — instead of chrome-vanadium steel, carbon steel is used, which wears out faster. Also, such kits may be missing 10 and 11 mm wrenches (critical for braking systems) or 15 and 17 mm heads (needed for attaching shock absorbers).

⚠️ Attention: If the set does not contain socket heads for 12 and 13 mm, it can hardly be called full-fledged - these dimensions are used for mounting most attachments (generator, air conditioning compressor).

Availability of 10, 11, 12, 13 mm keys (critical for cars)

Material - chrome vanadium steel (Cr-V marking)

Availability of deep socket heads (for long bolts)

Convenience of the ratchet handle (should rotate smoothly, without play)

How to use a key set: tips for beginners

Even the most expensive set of keys is useless if you don't know basic rules of work with him. Here are the key recommendations:

1. Choosing the right key

Always use a key that fits tightly onto the nut or bolt. If the key dangles, the risk of edges breaking increases by 3–4 times. For example:

• 🔧 For rounded nuts (for example, on wheels) is better suited spanner wrench.
• 🔩 For "stuck" fasteners use socket head with extension — it distributes the force evenly.
• ⚙️ For hard to reach places (for example, in the engine compartment) will be useful universal joint.

2. Unscrewing technique

Never pull the key towards you - this way you risk breaking the thread. Correct sequence:

1. Place the wrench on the nut all the way.
2. Pull to the side (perpendicular to the axis of the bolt), and not towards itself.
3. If the nut does not budge, use penetrating lubricant (for example, WD-40) and wait 10–15 minutes.

3. Working with ratchet handle

Ratchet handle allows you to unscrew nuts without removing the head — this saves time when working in cramped conditions (for example, when replacing a starter). However, remember:

• ⚠️ Do not apply excessive force - the ratchet mechanism may break.
• ⚠️ Lubricate the ratchet regularly (1-2 drops of machine oil every six months).

What to do if the key breaks the edges of the nut?

If the edges of the nut are “slipped”, try the following methods:

1. Smaller spanner - sometimes you manage to catch on to the remaining protrusions.

2. Grinder or hacksaw for metal - cut a slot for a flat-head screwdriver and unscrew the nut like a screw.

3. Special extractors (for example, Irwin Bolt-Grip) - they “bite” into the metal.

4. Welding - weld a new bolt to the nut and unscrew it.

If all else fails, all that remains is to cut off the nut with a grinder (but this is a last resort!).

Storage and care: how to extend the life of an instrument?

The service life of a set of keys directly depends on storage and care conditions. Here are the basic rules:

1. Corrosion protection

Even chrome keys can rust if stored in a damp area. To avoid corrosion:

• 🌧️ Store the set in dry place (ideally in a heated garage).
• 🧴 Wipe your keys every 3-6 months a rag soaked in machine oil.
• 📦 If the case is not sealed, put it in silica gel bags (they absorb moisture).

2. Storage organization

Chaotic storage leads to the loss of small parts (for example, 4 or 5 mm socket heads). Optimal options:

• 🔧 Case with rubberized cells — prevents tools from falling out during transportation.
• 🏗️ Magnetic panel — convenient if the set is used frequently.
• 📋 Inventory list — print out the contents of the set and check the boxes for the presence of each key.

3. Cleaning after use

After working with dirty parts (for example, when changing the oil), clean the keys from oil and metal shavings:

1. Wipe down your tools dry rag.
2. To remove stubborn stains, use kerosene or white spirit.
3. Do not wash your keys with water - this will accelerate corrosion!

⚠️ Attention: If there are traces of rust on the keys, remove it fine sandpaper (400-600 grit) and coat the metal with a thin layer Litola-24 or WD-40. Do not use aggressive products (for example, rust converter) - they may damage the chrome plating.

Common mistakes when choosing and using a key set

Even experienced car owners sometimes make mistakes that lead to tool failure or damage to car parts. Here are the most common:

1. Buying a set "for growth"

Many beginners buy sets with keys up to 32 mm, although in 90% of cases sizes up to 24 mm. Large keys take up space in the case and increase its cost, but are used extremely rarely (for example, for trucks).

2. Use of keys for other purposes

Some "craftsmen" use open-end wrenches as hammers or levers - this leads to deformation of the metal. Remember:

• 🔧 Open-end wrench - only for unscrewing/twisting.
• 🔨 For strikes use drift or soft-faced hammer.

3. Ignoring the torque wrench

Many 108 piece sets do not include torque wrench, although it is critical for working with:

• 🚗 Wheel bolts (undertightened ones will cause the wheel to fall off, overtightened ones will break the thread).
• ⚙️ Cylinder head (incorrect tightening torque leads to gasket burnout).
• 🔧 Brake calipers (upholstery worsens the braking distance).

If your kit does not include a torque wrench, purchase it separately (cost from RUB 1,500).

4. Storing keys in a heap

Throwing all your wrenches into one drawer is a sure way to lose small sockets or warp your ratchet handle. Use organizers with compartments or at least divide the tools by type (open-end, cap, end).

5. Saving on material

Cheap Carbon Steel Keys bend under heavy loads and lick the edges nuts For example, when unscrewing a stuck exhaust manifold bolt, a budget key may simply break, leaving you with a half-disassembled car.
