Spanner sets

Spanner sets are used for tightening and loosening nuts and bolts across a wide range of mechanical, repair and industrial maintenance applications. This product group covers many different constructions such as double open end, combination, double ring, reversible ratcheting, tube (flare nut) spanners and specialised lines. The sets meet technical standards DIN 3110, DIN 3113 Form A and Form B, ISO 3318, ISO 7738, with sizes ranging from 6mm to 55mm. Several models such as 100S-SB, 205S-MSB, 204-R S8M come in roll-up plastic pouches or fabric pouches, convenient for transport. Other sets such as MS-2, OMS-9, OMS-50 use ABS plastic trays or die-cut foam inlays, suited to modular tool trolleys. All items are genuine, imported from Germany, with Chrome Vanadium quality assurance and warranty according to the distributor's policy.

A spanner set is a group of mechanical hand tools designed to tighten or loosen nuts and screws in many different applications. On today's market, spanner sets come in many types, constructions and piece counts, serving needs from basic to professional in mechanical engineering, repair, equipment maintenance and industry.

Classification of spanner sets by construction

Within the spanner set range, the variety of constructions is clear, including double open end, combination, double ring, ratcheting spanners, flare nut spanners and sets dedicated to specific purposes.

Double open end spanner sets are a common group, usually comprising many different sizes and meeting standards such as DIN 3110. For example, the ELORA 100S-SB double open end spanner set comes in a roll-up plastic pouch, convenient to carry and store. Other sets such as ELOFORT 2S10M or 2S12M also cover sizes from 6mm to 32mm, suitable for many common nuts and bolts.

The combination spanner set combines a ring end and an open end on the same spanner. Sets such as ELORA 203S, 205S, ELOFORT 3S12M, 3S10M all meet technical standards such as DIN 3113 Form A or B. Some sets are designed specifically for tool trolleys, with plastic trays or foam inlays for tidy arrangement, convenient in use and storage.

Double ring spanner sets are typically used for applications requiring firm grip and high tightening force. For example, the 5S 12M ELOFORT double ring spanner set includes 12 pieces and meets DIN 838/ISO.

In addition, there are ratcheting spanner sets with a ratchet mechanism, allowing fast operation without lifting the spanner off the nut. Sets such as ELORA 204-S8M OMS, 204-JS8M, MS-10, OMS-32 feature a ratcheting ring end with a 72-tooth mechanism and a small effective swing angle, suitable for positions with limited working space.

Flare nut spanner sets and specialised spanner sets

Alongside the general-purpose types, the range also includes flare nut spanner sets such as ELORA 117S, 121S8M, used for pipes, elbow fittings, or positions requiring work on flare nuts of fuel and hydraulic lines. Some non-sparking spanner sets such as ELORA 01300S AlBr, 0130001S are made from aluminium-bronze alloy for use in environments sensitive to flammable substances.

Construction and materials

The spanner sets in this range are mainly made from Chrome Vanadium steel, hot forged or high-pressure forged, with surfaces usually matt chrome plated or polished to increase durability and corrosion resistance. Some sets feature jaws inclined 15 degrees to the body, rounded heads, or deep offset ring ends for easier operation in obstructed positions. Mini spanner sets such as ELORA 156S are small in size, suited to work requiring high precision and narrow working space.

Packaging and storage

Depending on the intended use, spanner sets may be packed in plastic pouches, fabric pouches, metal boxes or rigid plastic trays. Some sets dedicated to tool trolleys are arranged in foam inlays, keeping tools tidy and making it easy to check the piece count during use. Some special versions such as ELORA 100-S8 or 205-S12 are packaged separately, serving anniversary occasions or collectors' needs.

Technical standards

Many spanner sets in this range meet international technical standards such as DIN 3110, DIN 3113, DIN 896, DIN 7444, ISO 3318, ISO 7738. Compliance with these standards ensures consistency of dimensions, accuracy and compatibility with common nuts and bolts on the market.

Size ranges and piece counts

Spanner sets generally offer diverse size ranges, from small sets of only 5-6 pieces up to large sets of as many as 37 pieces, serving many different usage needs. Some specialised sets focus only on large sizes, from 36mm to 55mm, suited to heavy industrial applications. Conversely, mini sets or sets for tool trolleys usually have smaller size ranges, serving routine repair and maintenance work.

Practical applications

Spanner sets are widely used in mechanical engineering, maintenance, equipment repair, machinery assembly, the automotive, motorcycle and electrical appliance industries, and many other trades. Some sets are designed specifically for special environments such as explosion-protected areas or work with hydraulic and pneumatic systems.

Spanner sets form a group of mechanical hand tools that is diverse in type, construction, piece count and technical standard. Choosing a suitable spanner set helps meet work requirements effectively, from basic to advanced.
