Elora Metric and Imperial Socket Set, 1/2" Sq. Dr. (27 Piece)

The Elora 27-Piece Metric and Imperial Socket Set, 1/2" Square Drive (770-OKLAMU) is a professional-quality dual-system socket set that brings together comprehensive metric AND imperial coverage in a single, high-quality kit. Combining 11 metric bi-hexagon sockets covering 10mm to 32mm with 11 imperial bi-hexagon sockets covering 7/16" to 1" AF, a high-quality 32-tooth reversible ratchet with Quatrolit® soft-grip handle, two extension bars, a sliding T-bar, and a universal joint, the 770-OKLAMU is the answer for workshops that need to handle both fastener systems with equal confidence and quality.

Manufactured from chrome vanadium steel — hardened, tempered, and chrome plated — and supplied in a heavy-gauge steel storage case with custom plastic insert, the 770-OKLAMU is the kind of professional-grade tooling that earns its place in mixed-environment workshops and stays there for decades.

The Dual-System Advantage

Most workshops eventually face the reality that both metric and imperial fasteners appear regularly across their workload:

• Independent garages servicing both modern (metric) and classic or American (imperial) vehicles
• Agricultural workshops handling modern machinery (metric) alongside vintage and American equipment (imperial)
• Marine workshops with both European (metric) and American (imperial) vessels
• Plant maintenance teams working on equipment of varying age and origin
• Restoration specialists dealing with originally-imperial vehicles fitted with modern (metric) replacement components
• Mobile mechanics who can't predict what they'll face on the next call

Trying to handle both systems with a single fastener set means rounded fasteners, damaged tools, and frustration. The 770-OKLAMU eliminates the compromise — providing proper coverage of both systems in a single, well-organised, professionally-built kit.

Built to the Elora Standard

Elora has been manufacturing professional-quality hand tools in Germany since 1924, and the brand is synonymous with the build quality and precision that serious trade users demand. The 770-OKLAMU is manufactured to recognised international standards:

• DIN 3120 / ISO 1174 — socket drive square specification
• DIN 3122 / ISO 3315 — hand-operated socket wrench specification
• DIN 3123 / ISO 3316 — extension bar specification
• DIN 3124 / ISO 2725 — universal joint specification

This isn't a set of tools that "looks" professional — it's a set built and certified to the same standards used by professional mechanical industries worldwide.

Chrome Vanadium Steel Construction

The 770-OKLAMU is built around chrome vanadium steel — the standard alloy for high-quality hand tools because of its excellent combination of strength, toughness, and durability. Every socket and accessory is:

• Hardened to provide the wear resistance needed for repeated heavy use under high torque
• Tempered to deliver the toughness that prevents brittle failure when the going gets tough
• Chrome plated for outstanding corrosion resistance and a long-lasting professional finish

The result is sockets and accessories that hold their precision over years of professional use, resist the rust and corrosion that quickly degrade lesser tools, and continue to perform like quality kit long after cheaper alternatives have been replaced.

Bi-Hexagon Sockets for Real-World Performance

All 22 sockets in the 770-OKLAMU are bi-hexagon (12-point) design — providing significant practical advantages:

• Better access angles — bi-hex sockets engage the fastener at 12 positions, meaning the ratchet only needs to turn 30° (rather than 60°) to find a new engagement position. In confined spaces, this is genuinely transformative
• Easier fitment on damaged fasteners — the 12-point engagement geometry often allows the socket to grip slightly rounded or damaged fastener heads that a 6-point socket would slip on. This is particularly valuable on aged classic vehicle fasteners
• Faster work — the ability to start a fastener at any of 12 positions speeds up engagement when working blind or in awkward locations
• Compatibility with both hexagon and 12-point fasteners — bi-hex sockets work equally well on conventional hex fasteners and the 12-point fasteners found on some automotive and engineering applications

Elora's precise manufacturing ensures the bi-hexagon design grips fasteners properly without the slip that lesser 12-point sockets are sometimes accused of.

32-Tooth Reversible Ratchet with Quatrolit® Soft-Grip Handle

The included 32-tooth reversible ratchet delivers the smooth, robust action that's a hallmark of Elora's German engineering. The 32-tooth mechanism provides a strong, reliable engagement particularly suited to the higher torque levels that 1/2" drive heavy-duty work demands. The reversible function allows quick changes between tightening and loosening without removing the socket from the fastener — essential for productive workshop work.

The Quatrolit® soft-grip handle is an Elora signature — providing exceptional grip even with oily, greasy, or wet hands, while remaining comfortable for extended use. For heavy-duty 1/2" drive work, where significant force is regularly applied through the handle, the comfort and grip of the Quatrolit® design are particularly valuable.

Comprehensive Metric Coverage: 10–32mm

The metric side of the 770-OKLAMU offers 11 bi-hexagon sockets covering the most useful sizes for everyday heavy-duty work:

11 x Metric Bi-Hexagon Sockets: 10, 11, 13, 14, 17, 19, 22, 24, 27, 30, 32mm

This focused range covers the practical core of metric fastener work — the 10–17mm sizes that dominate engine bay and chassis work, 19mm and 22mm for suspension and driveline, and the larger 24–32mm sizes for wheel nuts, crankshaft pulleys, and substantial structural fasteners.

Comprehensive Imperial Coverage: 7/16" to 1" AF

The imperial side of the 770-OKLAMU offers 11 bi-hexagon sockets covering the most useful imperial sizes:

11 x Imperial Bi-Hexagon Sockets: 7/16, 1/2, 9/16, 19/32, 5/8, 11/16, 3/4, 25/32, 7/8, 15/16, 1" AF

Note the inclusion of the less-common but specifically useful 19/32" and 25/32" sizes — these are sizes that appear on classic vehicles and certain specialist applications, and their inclusion shows the depth of Elora's understanding of real imperial fastener work. Many dual-system sets skip these sizes; the 770-OKLAMU includes them precisely because professionals need them.

Comprehensive Accessory Pack

The 770-OKLAMU includes a well-judged accessory selection for the access challenges encountered in heavy-duty work across both fastener systems:

• 32-Tooth Reversible Ratchet with Quatrolit® soft-grip handle for primary driving work
• 125mm Extension Bar for moderate access reach and additional working clearance
• 250mm Extension Bar for deep recessed access — particularly valuable on commercial vehicle, agricultural, and structural work
• Sliding T-Bar for balanced two-handed leverage on tight fasteners and for applications where ratchet access isn't possible
• Universal Joint for accessing fasteners at angles where straight drive can't reach

The combination of two extension bars at different lengths, plus the universal joint, transforms what's accessible across both metric and imperial work.

Heavy-Gauge Steel Storage Case

The 770-OKLAMU is supplied in a heavy-gauge steel storage case with a custom plastic insert — a significant step up from the plastic blow-moulded cases used for lesser tool sets. The steel case provides genuine protection during transport and storage, the custom plastic insert keeps every socket and accessory in its dedicated location for easy identification and quick selection, and the overall presentation reflects the quality of the tools inside.

Ideal Applications

The 1/2" drive format combined with comprehensive metric AND imperial coverage makes the 770-OKLAMU perfectly suited to a uniquely wide range of professional workshop tasks:

• Mixed-fleet independent garages — modern metric vehicles plus classic and American imports
• Classic vehicle restoration with modern components — original imperial fasteners alongside metric replacements
• Agricultural workshops — modern metric machinery plus vintage and American equipment
• Plant maintenance — equipment of varying age, origin, and fastener system
• Marine workshops — both European (metric) and American (imperial) vessels
• Commercial vehicle workshops — handling vehicles from multiple eras
• Mobile mechanics — comprehensive coverage for whatever the next call brings
• Vehicle dealerships — mixed inventory including imports
• Restoration project work — eclectic combinations of fastener systems
• Heavy fabrication and engineering — projects involving both fastener standards

A genuinely versatile set for any operation where you can't predict in advance whether the next fastener will be metric or imperial — and where having the right socket at hand matters more than maintaining doctrinal purity about fastener systems.
