Total length: ≈ 332 mm (about 13 inches)

High-quality construction with a safety mechanism to prevent accidental release.

NUMBER H2584-13

NUMBER H2584-13

Hazet 2584-13 is a special wrench (also called a suction pipe wrench or intake manifold tool) made by Hazet designed specifically for VAG group vehicles (Volkswagen, Audi, SEAT, Škoda) with common rail diesel engines to access and tighten/loosen the hard-to-reach fastening screw(s) on the intake manifold / suction pipe / intake bridge, which is located behind the high-pressure fuel pump. In many of these engines, the screw is extremely awkward to reach with standard tools due to tight engine bay space and obstructions — this tool solves that problem cleanly.It's particularly useful on 3-cylinder common rail diesel engines, such as the 1.4 TDI / 1.6 TDI variants (e.g., Audi A1 from ~2014 onward, VW Polo, Golf, SEAT Ibiza, Škoda Fabia/Citigo, etc.), but it appears in service procedures for various other VAG TDI models as well.Key SpecificationsDrive: 3/8" square (10 mm) – you attach a ratchet, torque wrench, or extension here

Output / head: External 12-point (double hexagon / bi-hex) profile, size 13 mm

Design: "Suitcase handle" style – offset / angled / cranked shape that provides better access and allows proper torque application without the handle hitting surrounding components

Length: ≈ 166 mm (about 6.5 inches)

Finish: Chrome-plated

Made in Germany

NUMBER H4803

NUMBER H4803

Hazet 4803 refers to a family of specialized releasing tools (also called cap removal tools or lid wrenches) made by Hazet for the coolant expansion tank (reservoir / surge tank) on VAG group vehicles (Volkswagen, Audi, SEAT, Škoda, and increasingly their electric/hybrid models on MQB platform and similar).These tools are designed to safely and easily loosen very tight or stuck caps on the coolant expansion tank without damaging the plastic lid, tabs, or sealing surfaces — something that happens frequently because the caps are often over-tightened or seized from age/heat cycles.There are two main variants people refer to when searching for "Hazet 4803":Hazet 4803-1Drive: 1/2" square (12.5 mm)

Purpose: Releases stuck lids on VAG coolant expansion tanks (older / various models)

Design: Precise fit that engages the cap's tabs or hex features perfectly

Key benefit: Allows high torque application via ratchet or breaker bar without rounding off or cracking the cap

NUMBER H2567-16

Made in Germany

Main Purpose & ApplicationThis tool is used during manual gearbox oil changes (drain and refill) on many VAG group vehicles (Volkswagen, Audi, SEAT, Škoda) from the late 1990s through the mid-2000s, and sometimes on related models or Porsche equivalents.Common vehicles that require it include:Audi: A2, A3 (8L), A4 (B5/B6), A6 (C5), TT (8N)

Volkswagen: Passat B5, Golf 4 (Mk4), LT, Transporter T4, T5 (early models)

Škoda: Fabia, Octavia (1U/1Z)

Seat: Various models with matching gearboxes (e.g., Ibiza, Leon, Toledo)

These transmissions (often 02J, 02A, 01M, or similar manual gearboxes) use an M16 XZN plug with a center guide pin for the drain/fill points. Standard XZN sockets without the pin won't fit properly or can damage the plug.

NUMBER H2901-G7

NUMBER H2901-G7

The Hazet 2901G-7 (often written as 2901-G7 or 2901 G-7) is a specialized brake caliper joint socket (also called a universal joint / hinged / swivel hex bit socket) made by Hazet, the renowned German premium tool manufacturer.It's designed specifically for accessing and turning the internal hex (Allen) screws that secure rear brake calipers in tight, obstructed spaces — a common challenge on many modern vehicles where the screws are recessed or angled awkwardly.Key SpecificationsDrive: 3/8" square (10 mm), hollow

Output: Internal hexagon (Allen / hex) profile, 7 mm

Special feature: Built-in universal joint / hinge (swivel head) — allows the socket to pivot and work around obstructions or at awkward angles without needing a separate universal joint adapter

Length: ≈ 50 mm (about 2 inches)

Weight: ≈ 60 g (0.13 lb)

Finish: Chrome-plated

Made in Germany

Main Purpose & ApplicationsUsed to loosen and tighten the rear brake caliper mounting/guide pin screws (usually the ones that hold the caliper to the bracket or carrier) on vehicles that use 7 mm internal hex fasteners in hard-to-reach rear brake setups.Common vehicles include:BMW: 3 Series, 5 Series, 8 Series (various generations, especially models from mid-2000s onward)

Volkswagen: Golf 7 (Mk7, model year 2013 →), and related MQB-platform cars

NUMBER H2540-1

NUMBER H2540-1

The Hazet 2540-1 is a premium timing belt pulley counterholder (also called a timing pulley locking tool, retainer, or Arretierwerkzeug) manufactured by Hazet, the high-end German tool maker.It's a specialized engine timing tool used to hold the timing belt pulleys steady (preventing rotation) while loosening or tightening the large central bolt on the pulley. This is critical during timing belt replacement, camshaft work, or related engine repairs to avoid damaging components or shifting timing.Key SpecificationsType: Counterholder with two replaceable pins / pegs

Pin spacing / distances: 100 mm and 46 mm (two different hole patterns to fit various pulley designs)

Opening width: 33 mm

Overall length: ≈ 722 mm (about 28.4 inches) — long handle for excellent leverage

Handle: Ergonomic with dip-coating (rubberized grip for comfort and better control)

Material: High-quality tool steel

Finish: Chrome-plated

Made in Germany

Main Purpose & ApplicationsPrimary use: Holding camshaft pulleys, crankshaft pulleys (harmonic balancer / damper), or injection pump pulleys stationary while torquing or untorquing the center bolt (which often requires very high torque — 100–300+ Nm depending on the engine).

Without a proper counterholder, the pulley can spin freely when you apply force, making the job impossible or risking stripped bolts/damage.

Commonly used on older diesel engines (especially with belt-driven injection pumps) and many petrol engines with timing belts.

NUMBER H2593-4

NUMBER H2593-4

The Hazet 2593-4 is a specialized shock absorber crown wrench (also called a shock absorber pin spanner, drive nut tool, or slotted crown socket wrench) made by Hazet, the premium German tool manufacturer.It's a compact, high-quality tool designed specifically for removing and installing the piston rod nut (or top mount nut) on the front strut/shock absorber assemblies in many VAG group vehicles (Volkswagen, Audi, SEAT).Key SpecificationsOuter diameter / crown size: 14.5 mm

Pin / slot width: 5 mm (the two pins engage into the slots or holes on the nut)

Drive: 22 mm hexagon (external hex) – you attach a 22 mm wrench, socket, or ratchet here

Material: High-quality steel

Finish: Chrome-plated

Made in Germany

Main Purpose & ApplicationsUsed to hold or turn the slotted crown nut at the top of the front strut piston rod while you loosen/tighten the central nut (usually with a socket on the piston rod itself).

This prevents the piston rod from spinning during shock absorber replacement, strut service, or top mount bearing changes — a common issue on MacPherson strut setups.

Primary vehicles: Volkswagen: Golf II (from ~1988), Golf III, Jetta, Vento, Passat (B3/B4 era and some later), and various other models with similar front suspension

Audi: Many 80/90, A3 (early), A4 (B5 era), etc.

SEAT: Ibiza, Toledo, León (corresponding generations)

It's especially useful on older VAG front-wheel-drive cars (late 1980s–early 2000s) where the top nut has two narrow slots/holes spaced for a 5 mm pin tool.

Why Mechanics Prefer ItThe exact 14.5 mm diameter with 5 mm pins fits perfectly into the nut's slots without slipping or rounding edges — cheap universal pin spanners often fail here.

Allows safe, high-torque application (the piston rod nut is often very tight due to thread locker or corrosion).

Compact design works in tight engine bays/wheel wells.

NUMBER H1779-1

NUMBER H1779-1

Hazet 1779-1 is a premium universal ball joint puller (also called a ball joint separator or Kugelgelenk-Abzieher) manufactured by Hazet, the renowned German high-end tool brand.It's a manual, screw-type puller designed for safe and damage-free removal of ball joint pivots / ball pins in steering and suspension systems.Key SpecificationsJaw opening / mouth width: 23 mm (fits most standard automotive ball joint tapers)

Clamping range / span: Up to 65 mm (wide enough for many tie rod ends, stabilizer links, control arms, etc.)

Special features:Stepless / continuous height adjustment (allows precise positioning)

Tilting / swiveling lower part (adapts to angled or offset ball joints)

Forged steel construction with a strong central forcing screw

Finish: Chrome-plated or similar corrosion-resistant coating

Made in Germany

Main Purpose & ApplicationsPrimary use: Pressing / pushing out seized or rusted ball joint pins (tapered studs) from their seats in steering knuckles, steering arms, tie rod ends, stabilizer links (sway bar links), control arms, and similar suspension components.

It applies even, controlled pressure directly to the ball joint stud, avoiding the damage often caused by hammering, pickle forks, or improper leverage tools.

Universal fit: Works on a very wide range of passenger cars, light trucks, and SUVs — especially popular for European makes (VW, Audi, BMW, Mercedes, Porsche, Volvo, etc.) but also effective on many Asian and American vehicles with standard ball joint sizes.

Why Mechanics Prefer ItGentle & precise: Minimizes risk of damaging the ball joint boot, steering knuckle, or threads — crucial when reusing components or during alignments.

High leverage: The large forcing screw and long handle provide substantial force without needing excessive effort.

Adjustable design: The stepless height and tilting lower jaw make it versatile in tight wheel wells or awkward angles.

Extremely durable Hazet quality — built to withstand years of professional use without deforming or rounding.
