Elora Metric Socket Set, 3/8" Sq. Dr. (18 Piece)

The Elora 18-Piece Metric Socket Set, 3/8" Square Drive (870-JMU) is a professional-quality mid-drive socket set engineered for the versatile, everyday fastener work that sits at the heart of most workshop, automotive, and engineering tasks. Combining a focused range of 15 metric sockets covering 6mm to 22mm, a high-quality 72-tooth reversible ratchet with Quatrolit® soft-grip handle, a 150mm extension bar, and a sliding T-bar, the 870-JMU is built to handle the bulk of practical fastener work with the precision, durability, and quality Elora has been known for since 1924.

Manufactured from chrome vanadium steel — hardened, tempered, and chrome plated — and supplied in a heavy-gauge steel storage case with custom plastic insert, the 870-JMU is the kind of professional-grade socket set that earns its place in serious toolboxes and stays there for decades.

The 3/8" Drive Sweet Spot

The 3/8" square drive format is widely considered the most useful all-purpose socket drive for general mechanical work — and the 870-JMU is built around this sweet spot. 3/8" drive sockets and accessories are compact enough to work in tight spaces where 1/2" drive can't reach, yet substantial enough to handle the torque levels demanded by typical automotive, motorcycle, agricultural, and industrial fastener work.

For mechanics and engineers who want a single, versatile socket set that handles the majority of everyday tasks without compromise, 3/8" drive is the natural choice — and the 870-JMU delivers it with Elora's signature quality.

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 870-JMU is built to recognised international manufacturing 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 870-JMU 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
• Tempered to deliver the toughness that prevents brittle failure under load
• 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 Better Fastener Engagement

A standout feature of the 870-JMU is its bi-hexagon (12-point) socket range for the larger sizes. Unlike basic 6-point sockets that engage the fastener on six faces, bi-hexagon sockets engage on 12 points — providing significant practical advantages:

• Better access angles — bi-hex sockets engage the fastener at twice the number of positions, meaning the ratchet only needs to turn 30° (rather than 60°) to find a new engagement position, which is invaluable in confined spaces
• 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
• 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

For everyday workshop work, the bi-hexagon design simply makes life easier — and Elora's precise manufacturing ensures the sockets grip fasteners properly without the slip that lesser 12-point sockets are sometimes accused of.

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

The included 72-tooth reversible ratchet is one of the standout components of the set. The 72-tooth mechanism delivers a working arc of just 5° — meaning the ratchet can advance the socket in confined spaces where a coarser ratchet simply cannot operate effectively. For work inside engine bays, around suspension components, or in any restricted-access location, this fine-tooth design transforms productivity.

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. Combined with the smooth, precise feel of the German-engineered ratchet mechanism, it's a tool that's genuinely a pleasure to use over long workshop sessions.

Focused Socket Range: 6–22mm

The 870-JMU offers a well-judged socket range covering 6mm to 22mm, with the sizes chosen to match the fasteners most commonly encountered in everyday workshop work:

4 x Hexagon Sockets (6-point): 6, 7, 8, 9mm — the smaller sizes where 6-point engagement provides maximum strength on smaller fasteners

11 x Bi-Hexagon Sockets (12-point): 10, 11, 13, 14, 15, 16, 17, 18, 19, 21, 22mm — the practical "core" sizes that handle the vast majority of automotive, motorcycle, agricultural, and engineering fasteners

This focused range delivers the sizes that get used regularly, without padding the set with sizes that rarely see daylight. The result is a set that's compact, portable, and genuinely practical — every socket earns its place.

Practical Accessory Pack

The 870-JMU includes the core accessories needed for everyday fastener work:

• 72-tooth reversible ratchet with Quatrolit® soft-grip handle for the bulk of standard work
• 150mm extension bar for reaching recessed fasteners and providing additional working clearance
• Sliding T-bar for balanced two-handed leverage on tight fasteners and for applications where ratchet access isn't possible

This accessory selection keeps the set compact and focused while covering the most common access challenges in everyday work. For users who need more extensive accessory options, Elora's broader range includes additional extensions, universal joints, and specialist drivers compatible with the 870-JMU's 3/8" drive sockets.

Heavy-Gauge Steel Storage Case

The 870-JMU 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 3/8" drive format and 6–22mm socket range make the 870-JMU perfectly suited to a vast range of everyday fastener work:

• Automotive servicing and repair — engine bay work, suspension, brakes, exhaust
• Motorcycle workshop work — engine, frame, and ancillary fasteners
• Agricultural machinery servicing — tractor and equipment maintenance
• Light commercial vehicle work — van and light truck servicing
• Garden machinery repair — ride-on mowers, larger garden equipment
• Marine workshop work — outboard, inboard, and fitting maintenance
• General engineering and fabrication — machine assembly and maintenance
• Cycle workshop work (heavier components)
• DIY and home workshop — comprehensive everyday fastener coverage
• Field servicing and mobile mechanics — versatile portable toolkit

A genuine workshop core set for independent garages, motorcycle workshops, mobile mechanics, agricultural engineers, marine technicians, fabricators, and serious home workshop users alike.
