Elora Metric Socket Set, 1" Sq. Dr. (14 Piece)

The Elora 14-Piece Metric Socket Set, 1" Square Drive (780-10M) is a professional-grade heavy industrial socket set engineered for the substantial large-scale fastener work encountered in HGV, commercial vehicle, plant, agricultural, marine, and heavy engineering applications. Combining 10 large-format bi-hexagon metric sockets covering 36mm to 80mm, a robust reversible ratchet, two extension bars (200mm and 400mm), and a sliding T-bar, the 780-10M is built for the kind of substantial fastener work that lighter-drive socket sets simply cannot handle.

Manufactured from chrome vanadium steel — hardened, tempered, chrome plated, and polished — and supplied in a heavy-gauge steel storage case, the 780-10M brings genuine Elora professional quality to the heavy industrial end of the socket spectrum.

The 1" Drive Heavy Industrial Standard

The 1" square drive format is the established standard for the heaviest fastener work — the large nuts, bolts, and fasteners found on:

• HGV wheel hubs and axles
• Bus wheel and hub fasteners
• Agricultural tractor wheels and PTOs
• Plant equipment — excavators, loaders, dumpers, scrapers
• Marine drive components — propeller nuts, large shaft fittings
• Wind turbine components
• Heavy industrial machinery
• Rail and infrastructure fasteners
• Large structural bolting

These fasteners demand torque levels that simply cannot be safely or effectively applied through smaller drive sizes — making genuine 1" drive equipment essential for the workshops handling this kind of heavy work.

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 780-10M 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

For tools handling the substantial torque levels of 1" drive work, this kind of manufacturing certification matters significantly — both for performance and for operator safety.

Chrome Vanadium Steel Construction with Premium Finish

The 780-10M 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 extreme torque
• Tempered to deliver the toughness that prevents brittle failure under maximum load
• Chrome plated for outstanding corrosion resistance and a long-lasting professional finish
• Polished for that distinctive Elora professional appearance and easy cleaning

At 1" drive working torque levels, the quality of the steel and the precision of the manufacturing aren't optional — they're what stands between a successful job and a catastrophic tool failure. The 780-10M's chrome vanadium construction is built for the demands of heavy industrial work.

Bi-Hexagon Sockets for Heavy-Duty Performance

All 10 sockets in the 780-10M are bi-hexagon (12-point) design — providing significant advantages for heavy fastener work:

• Better access angles — engagement at 12 positions means just 30° of arc between positions, particularly valuable on the often awkward access locations of heavy fasteners
• Easier fitment on weathered or damaged fasteners — heavy industrial fasteners are frequently corroded, painted over, or partially damaged. The 12-point engagement often allows the socket to grip where a 6-point socket would slip
• Compatibility with both hexagon and 12-point fasteners

Elora's precise manufacturing ensures the bi-hexagon design grips fasteners properly under the high torque levels typical of 1" drive work.

Comprehensive Heavy-Duty Socket Range: 36–80mm

The 780-10M offers a professionally-judged heavy-duty range covering 36mm to 80mm — covering the substantial metric fasteners encountered in HGV, commercial vehicle, plant, agricultural, marine, and industrial work:

10 x Metric Bi-Hexagon Sockets: 36, 41, 46, 50, 55, 60, 65, 70, 75, 80mm

This range covers HGV wheel nuts and hub fasteners (typically 32–41mm range, with specific applications going larger), bus wheel fasteners, large agricultural fasteners, plant equipment fasteners, marine drive fittings, and substantial industrial fasteners. Every socket size addresses a recognised range of professional applications.

Heavy-Duty Accessory Pack

The 780-10M includes the core accessories needed for heavy industrial fastener work:

• Reversible Ratchet — built to handle the substantial torque levels of 1" drive work
• 200mm Extension Bar — for moderate access reach on hub and chassis fasteners
• 400mm Extension Bar — for deep recessed access on wheel, hub, and structural applications
• Sliding T-Bar — for balanced two-handed leverage, essential for the high-torque work that 1" drive sockets handle

Note that for the very highest torque applications (such as final torquing of HGV wheel nuts), a torque wrench is typically used to ensure correct fastener tension — the 780-10M's accessories handle the removal, installation, and primary tightening operations.

Heavy-Gauge Steel Storage Case

The 780-10M is supplied in a heavy-gauge steel storage case — the proper presentation for substantial heavy-duty tools. The case provides genuine protection during transport and storage, important for tools of this size and value, and the steel construction stands up to the realities of heavy workshop and yard environments.

Ideal Applications

The 1" drive format and 36–80mm socket range make the 780-10M perfectly suited to heavy industrial and commercial vehicle fastener work:

• HGV and bus workshops — wheel nuts, hub fasteners, large structural bolts
• Commercial vehicle servicing — heavy trucks, articulated vehicles, large vans
• Agricultural workshops — tractor wheels, PTO fasteners, large equipment bolts
• Plant maintenance — excavator, loader, dumper, scraper fasteners
• Construction equipment maintenance — heavy machinery fastener work
• Marine workshops — large drive components, propeller nuts, shaft fittings
• Industrial maintenance — substantial machinery fasteners
• Wind energy maintenance — turbine component fasteners
• Rail and infrastructure — heavy structural and component fasteners
• Heavy engineering and fabrication — substantial structural bolting

A core piece of equipment for HGV workshops, bus depots, agricultural service operations, plant maintenance facilities, marine workshops handling commercial vessels, industrial maintenance teams, and any operation where the largest fasteners are part of daily work.

Important Notes on Use

The 780-10M is engineered for heavy industrial and commercial vehicle fastener work where the substantial torque capacity of 1" drive is required. For ultimate torque applications (such as final tightening of HGV wheel nuts to manufacturer specifications), use of a calibrated torque wrench compatible with 1" drive is recommended to ensure correct fastener tension.

When working with large fasteners under high torque, always follow proper safety procedures: ensure secure footing and body position, anticipate the direction of fastener movement, use appropriate PPE including eye protection, and never use damaged or worn sockets at high torque levels. The 780-10M's chrome vanadium construction provides exceptional strength, but no socket is designed to handle damage to the engagement surfaces.
