Faithfull 30 Piece Metric and Imperial Hex Key Set | Professional Allen Keys

Faithfull Metric and Imperial Hex Key Set, 30 Piece

A compact, professional‑grade Allen key set combining metric and imperial sizes in one organised kit – ideal for furniture assembly, bike maintenance, machinery servicing and everyday DIY.

The Faithfull Metric/Imperial Hex Key Set, 30 Piece is designed for users who work with a wide range of equipment, from modern metric furniture to older or imported machinery using imperial fasteners. Rather than switching between multiple kits, this single, compact set gives you quick access to almost every common Allen key size you’ll encounter on site, in the workshop or around the home.

Complete Metric & Imperial Coverage

Many tools, bikes and machines in the UK use metric hex fasteners, while older equipment, some US‑origin products and legacy plant often rely on imperial (AF) hex bolts. This 30‑piece Faithfull set combines both systems, helping you:

– Work confidently on mixed‑origin machinery (UK, EU, US).
– Service bicycles and motorbikes using both metric and imperial fittings.
– Assemble flat‑pack and commercial furniture, racking, shelving and brackets.
– Maintain power tools, garden machinery and workshop equipment.

Having each size individually available avoids “making do” with a near match, which can lead to rounded heads, stripped fasteners and expensive replacements.

Construction & Technical Information

– Material: High‑quality, hardened steel hex keys for strength and long life.
– Finish: Typically supplied with a protective finish (e.g. black oxide or similar) to help resist corrosion and surface wear.
– Manufacturing quality: Designed for accurate hex geometry and a snug fit in the fastener head, minimising slip and cam‑out.

Hex keys of this type are often manufactured to meet or align with commonly used industry standards for hex keys, such as:

Detailed Use Cases & Practical Scenarios

1. Furniture Assembly & Shopfitting

Use this Faithfull hex key set when:

– Assembling flat‑pack wardrobes, beds, desks, shelving and TV stands.
– Installing commercial racking and shopfitting systems.
– Fitting brackets and supports to walls and frames that use hex head fixings.

Tip:
Most flat‑pack kits include a single small Allen key. Swapping to the Faithfull keys gives you better leverage, comfort and control, reducing the risk of sore hands and stripped fixings on larger jobs.

2. Bicycle & E‑Bike Maintenance

Essential for:

– Adjusting seat height and angle.
– Setting handlebar rotation and stem alignment.
– Fine‑tuning brakes, derailleur stops and accessories such as lights and racks.

Tip:
Keep the most commonly used sizes (often 4mm, 5mm, 6mm) in a smaller on‑bike tool kit, and use the full Faithfull set at home for more in‑depth servicing.

3. Automotive, Motorbike & Garage Jobs

Ideal for:

– Adjusting fairings, guards and panels on motorbikes and scooters.
– Installing aftermarket accessories, mounts and brackets on vehicles.
– Working on **garage equipment** like stands, benches and storage systems.

Tip:
Some imported accessories use imperial hex fittings. The combined metric/imperial set means you can service and adjust them without damaging the fasteners.

4. Workshop, Engineering & Light Industrial

Use this set for:

– Maintaining machine guards, panels and covers.
– Adjusting tooling head positions, stops and clamps.
– Building or modifying jigs, fixtures and rigs.

Tip:
Store the set close to frequently adjusted equipment. Using the correct hex size every time reduces wear on both fasteners and machines, keeping equipment in better long‑term condition.

How to Use the Faithfull Hex Key Set (Best Practice)

Step‑by‑Step Usage Guide

1. Identify the fastener type and size
– Check whether the fixings are likely to be metric or imperial (e.g. European furniture is usually metric; older US machinery may be imperial).
– Test fit the key by hand – it should slide in fully and snugly with no wobble.

2. Choose the correct arm for leverage
– Use the short arm of the L‑key inside the fastener when you need more turning leverage (turn using the long arm).
– Use the long arm inside the fastener when working in tight spaces or where less torque is required.

3. Insert fully before applying torque
– Push the hex key fully into the socket to maximise contact area.
– Keep the key square to the fastener to avoid rounding.

4. Apply steady pressure
– Turn the key with steady, controlled pressure rather than sudden jerks.
– For stubborn fasteners, a small extension (like sliding a tube over the key) can increase leverage, but be careful not to overtighten or snap smaller keys.

5. Avoid over‑tightening
– Tighten only until secure; over‑torqueing can strip the fastener or damage the material it is fixed into.
– For critical applications (e.g. bike stems, carbon components), always follow the manufacturer’s recommended torque values and use a torque wrench when necessary.

6. Care and maintenance
– Wipe keys clean after use, especially if exposed to oil, moisture or dirt.
– Store the keys back in their marked holders to prevent loss and to keep sizes quickly accessible.

> For a precise, up‑to‑date size list, please refer to the product packaging or the latest Faithfull specification sheet on their website or your supplier’s product page.

2. Is this hex key set suitable for professional and trade use?

Yes. The hardened steel construction, accurate hex profiles and mixed metric/imperial coverage make it well suited to:

– Tradespeople (carpenters, shopfitters, maintenance teams)
– Mechanics and bike technicians
– Workshop and light industrial environments

It’s robust enough to be your primary workshop hex key set.

3. Will these Allen keys work on both UK and US‑made equipment?

Yes. This is exactly where a mixed metric/imperial (AF) hex key set shines:

– UK and EU equipment – often metric.
– US‑origin tools and machinery – often imperial (inch).

Having both in one kit ensures you’re not caught out when working on imported or legacy equipment.

4. Are these hex keys rust‑resistant?

The keys are supplied with a protective finish (such as black oxide) that offers some resistance to corrosion but regular maintenance is required.

For best results:

– Store the keys clean and dry in their holders.
– Wipe off moisture, oils or chemicals after use.
– In damp environments, an occasional light wipe with an oily cloth can further reduce rust risk.

5. Can I use this set for bike and e‑bike maintenance?

Absolutely. This Faithfull hex key set is ideal for:

– Adjusting stems, handlebars, seat posts and saddles.
– Servicing brakes, derailleurs and gear shifters.
– Installing racks, cages, lights and accessories.

For delicate parts (e.g. carbon components), always follow manufacturer torque guidance and consider a torque wrench.

6. What is the difference between this Faithfull set and a basic budget Allen key set?

Key differences often include:

– Mixed metric & imperial coverage vs only metric on basic sets.
– Hardened steel for better durability, rather than softer, easily rounded keys.
– More precise hex tip geometry for a better fit and less slippage.
– Organised, marked holders so you can identify and store keys properly.

This means fewer rounded bolts, less frustration and longer‑lasting tools.

7. How do I avoid rounding or stripping hex bolts?

Follow these guidelines:

– Always use the correct size – the key should be a snug fit.
– Insert the key fully and keep it straight.
– Apply steady pressure, not sudden jerks.
– Avoid using oversized levers on very small keys (e.g. 1.5mm, 2mm).
– If a bolt is corroded or seized, use a penetrating oil and allow some time before attempting removal.

8. Do these hex keys comply with any standards like DIN or ISO?

Many quality hex key sets are manufactured to align with recognised standards such as DIN 911 or ISO 2936, which specify dimensions and tolerances for fit.

> To confirm the exact standard(s) applicable to this specific Faithfull Metric-Imperial Hex Key Set, 30 Piece, please check the current Faithfull technical documentation or contact the supplier, as details may be updated over time.
