Classification by working head structure

Double open-end spanners serve quick operations with nuts in easily accessible positions. This type has two different sizes on the same tool, helping reduce the number of tools to carry. Code 100 complies with DIN 3110 and ISO 3118 standards, considered the most classic and common type. Code 3- also follows DIN 3110 standard, Chrome Vanadium material hot-forged at high pressure, satin-finish surface with chrome coating. Inch system is available through code 100A, meeting DIN 3110 and ISO 3318.

Combination spanners combine ring end and open end on the same size. Ring end cuts 12 points, effective rotation angle, suitable for limited space. Code 3- follows DIN 3113 Form A standard, satin-finish surface, embossed jaw size. Code 203- also complies with DIN 3113 Form A, ring end angled 15 degrees to the body, creating convenience when working at inclined angles. High-offset types like code 205- following DIN 3113 Form B have deeply offset ring end, serving bolt positions located in recesses.

Double ring spanners are suitable for operations requiring firm grip and minimal slip. Code 5- follows DIN 838 and ISO 3318 standards, both ends same size, high or deep offset. Code 110M- complies with DIN 838, ISO 3318, ISO 1085 and ISO 10104, commonly called Z-spanner due to its distinctive shape. Short types like code 112- are compactly crafted, thick and short, chrome-nickel polished plating, suitable for tight spaces. Code 113- is ultra-short, thick body, robust, ensuring durability and wear resistance.

Specialized variants by application

Single ring-end spanners serve large sizes from 13mm to 95mm. Code 88- complies with DIN 3111 standard, only one size per tool, flat on two sides and the remaining side recessed toward the ring end. Surface treated by plating method, increasing corrosion resistance. This type is suitable for large nuts in heavy industry or equipment maintenance.

Black double open-end spanners like code 895- have two sizes on one tool, meeting DIN 895 and ISO 3318 standards. Made from high-grade Chrome Vanadium tool steel, black surface without plating, reducing light reflection. Slim-body types like code 156- are compactly designed, thin-ground heads, specialized for situations with limited operating space. Code 146- has one transverse jaw, belonging to obstruction wrenches group, serving hard-to-reach positions.

Open ring spanners like code 121- are used for opening pipes, spark plugs and hydraulic lines. Ring end curved 15 degrees and open at one section, creating conditions to fit onto fuel lines or hydraulic systems without complete removal. Ratcheting spanner code 123- has flexible socket head, easily accessing tight spaces and difficult positions in automotive and mechanical applications.

Material and manufacturing standards

Most spanners in this product group are manufactured from Chrome Vanadium 31 CrV 3, material code 1.2208. This material ensures hardness, load-bearing capacity and high wear resistance. High-pressure forging process helps increase metal structure density, extending tool life. Surface treated with satin-finish or chrome-nickel plating, providing corrosion resistance and easy jaw size observation.

Products comply with multiple international standards such as DIN 3110, DIN 3113, DIN 838, DIN 894, ISO 3318, ISO 1085, ISO 10102 and ISO 10104. DIN 3113 Form A standard specifies ring end angled 15 degrees to the body, while Form B has more deeply offset ring end. DIN 838 standard applies to high-offset double ring spanners, while DIN 3110 is for double open-end spanners. Compliance with these standards ensures compatibility and accuracy when working with internationally standardized nuts.

Sizes and measurement systems

The product group provides both metric and inch systems. Metric system includes sizes from 4mm to 110mm, suitable for European and Asian standard nuts. Inch system serves North American markets and some specialized industrial applications. Code 203A- following DIN 3113 Form A standard provides inch system sizes, while code 205A is the high-offset inch system variant following DIN 3113 Form B.

Spanner length ranges from ultra-short to extra-long types. Code 202- is ultra-short type with sizes from 4mm to 10mm, designed for limited space. Code 203XL is extra-long type following DIN 3113A standard, long body creating large leverage, suitable for operations requiring high torque. Length varies by jaw size, ensuring reasonable ratio between applied force and tool durability.

Special products and accessories

Both ends same size, jaws angled 15 degrees, suitable for humid environments or chemical contact. Straight double ring spanner code 120- follows DIN 837 Form B standard, 12-point ring, suitable for tightening and loosening nuts in positions not requiring angle.

Single thin open-end spanner code 894- has thin mouth and jaw angled 15 degrees, from 6mm to 110mm, complying with DIN 894. Creates convenience for working in narrow positions or requiring high thinness. Double square-end spanner code 227 size 8x10mm, length 285mm, works with square-head bolts in repair and maintenance applications.

Applications in industry and maintenance

Spanners of various types serve multiple fields from production, assembly to equipment maintenance. In automotive industry, combination spanners and ratcheting spanners help quick operations with engine nuts, suspension systems and brakes. Open ring spanners serve removal and installation of spark plugs and fuel lines. In mechanical production, double open-end and double ring spanners meet steel structure assembly, machinery and heavy equipment needs.

Industrial maintenance sector uses various spanners for inspection, tightening and component replacement. Slim-body and short spanners serve limited spaces such as inside electrical cabinets, piping systems or engine compartments. Extra-long spanners create large leverage, helping open rusted or over-tightened nuts without additional support tools.

Threaded rod spanners like code ABW are used for removing or installing threaded rods in construction and structural installation. Size 41 open-end spanner code 079003 is specialized for removing REMS UDKB diamond drill bits, serving concrete core drilling work. Lever arm code 855- is used with hand spanners, providing support for tasks requiring large force in assembly or disassembly.

Selecting appropriate spanners

Spanner selection depends on nut size, working space and torque requirements. For nuts in easily accessible positions, double open-end or combination spanners respond well. If space is tight, slim-body, short or ultra-short spanners are reasonable choices. When large torque is needed, extra-long spanners or types with lever arm support are more effective.

Measurement system is also important. Metric nuts require metric spanners, inch nuts require inch spanners. Using wrong system causes jaw slip, rounds nut corners and reduces tool life. Working environment affects material selection. Humid environments or chemical contact should use stainless steel spanners. Dry environments, plated Chrome Vanadium spanners sufficiently meet requirements.

Frequency of use and accuracy requirements also need consideration. Frequent work requires high-quality spanners, complying with DIN and ISO standards. Occasional or less demanding work can use common types. Check jaw size before purchase, ensuring precise fit with nuts to be operated.

Storage and safe use

Store spanners in dry places, avoiding moisture to prevent rust. After use, wipe clean oil and dirt with dry cloth. If exposed to chemicals or water, rinse clean and apply a thin oil layer to protect surface. Store in tool box or hanging rack, avoiding impacts causing jaw deformation.

When using, select correct spanner size for the nut. Jaw must fit tightly, not loosely. Place spanner perpendicular to nut axis, avoiding tilt causing slip. Pull spanner toward yourself instead of pushing away, reducing risk of hand slip. Do not use extension pipes or hammer blows on spanner to increase force, causing breakage or tool deformation.

Periodically inspect spanner condition. If jaw is worn, deformed or cracked, stop using and replace. Do not use spanner as hammer, lever or chisel tool. Follow manufacturer guidelines on torque limits and usage conditions. Proper storage and safe use help extend tool life and ensure work performance.

The spanner product group provides complete tools for all nut tightening and loosening needs. From double open-end spanners, combination spanners, double ring spanners to specialized variants, each type meets a specific application. Chrome Vanadium material, DIN and ISO standards, along with diverse design ensure durability and high performance. Selecting the right spanner type, proper storage and safe use help optimize work and extend tool life.
