Hex & Torx Keys

About Hex & Torx Keys

Hex and Torx keys are indispensable precision hand tools used across professional trades and DIY applications throughout the UK. Hex keys (also known as Allen keys) feature a six-sided hexagonal profile designed to drive socket head cap screws and bolts, whilst Torx keys use a six-pointed star pattern that delivers superior torque transfer and significantly reduces cam-out. MyToolShed.co.uk stocks a comprehensive range including L-shaped keys, folding multi-key sets, T-handle designs for enhanced leverage, and ball-end hex keys that allow angled access in confined spaces up to 25 degrees.

Available in both metric and imperial sizes, quality hex and Torx keys are manufactured from hardened chrome vanadium steel or S2 tool steel for maximum durability and resistance to rounding under demanding site conditions. Our selection includes trusted brands such as Draper, Bahco, BlueSpot, Bosch Professional, and DeWalt, featuring innovations like colour-coded sets for quick size identification, magnetic tips, jumbo sizes for heavy-duty industrial applications, and organised storage solutions including wall racks, pouches, and folding cases that keep keys accessible on busy job sites.

Applications

Hex and Torx keys serve essential functions across numerous trades and industries:

• Mechanics and Vehicle Technicians: Automotive repair, motorcycle maintenance, engine servicing, and brake system work
• Engineers and Fitters: Industrial machinery assembly, manufacturing plant maintenance, and equipment repair
• Bicycle Mechanics: Adjusting and servicing modern bikes with hex and Torx fasteners throughout frames and components
• Electricians: Electrical enclosures, consumer units, and modern security fastenings on junction boxes
• Furniture Assemblers: Flat-pack furniture assembly requiring quality hex keys for efficient, professional results
• Electronics Technicians: Precision miniature keys for computer equipment, smartphones, and delicate electronic devices
• Plumbers and Heating Engineers: Modern taps, valves, boiler components, and security Torx fastenings
• General Builders: Window fittings, door furniture, access panels, and countless maintenance applications
• DIY Enthusiasts: Household maintenance, repairs, and general home improvement projects

Choosing The Right Hex & Torx Keys

Size Range and Measurement System: Determine whether you need metric (typically 1.5mm to 10mm), imperial (1/16" to 3/8"), or comprehensive combination sets. Most UK applications use metric sizing, though older British machinery and American imports may require imperial.

Set Configuration: L-shaped keys offer versatility and compact storage, folding sets keep multiple sizes organised in pocket-friendly formats, whilst T-handle versions provide superior leverage and comfort for repetitive professional use. Ball-end hex keys are invaluable for confined spaces requiring angled access.

Material Quality: Choose chrome vanadium or S2 tool steel construction with hardened tips. Quality brands available at MyToolShed.co.uk like Bahco, Bosch Professional, and Draper resist rounding and deformation under torque, preventing fastener damage.

Storage Solutions: Wall-mounted racks, pouches, and folding cases prevent losses and maintain organisation. Colour-coded sets enable instant size identification, significantly speeding up workflow on time-sensitive jobs.

Specialist Features: Consider magnetic tips for holding fasteners in awkward positions, extra-long arms for increased leverage, or security Torx keys with centre holes for tamper-proof applications in public installations.

Frequently Asked Questions

What's the difference between Torx and hex keys?

Hex keys feature a six-sided hexagonal profile, whilst Torx keys use a six-pointed star shape. Torx designs provide superior torque transfer, reduce cam-out (slipping), and allow higher tightening forces without damaging fasteners. They're increasingly popular in automotive and manufacturing, though hex keys remain more common in general engineering and furniture assembly.

Should I buy metric or imperial hex keys?

Most modern UK applications use metric sizes (measured in millimetres), particularly European-manufactured equipment. However, older British machinery, American imports, and some bicycle components use imperial sizes (inches). Professional tradespeople typically invest in both systems, whilst DIY users should assess their most common applications before purchasing.

Are ball-end hex keys as strong as standard ones?

Ball-end hex keys sacrifice approximately 25% of torque capacity compared to standard straight-cut keys because the rounded tip has less material engaging with fasteners. However, they offer invaluable access advantages in confined spaces. Many professional sets include both types—using standard keys for initial loosening and final tightening, and ball-ends for accessibility in tight spots.
