Socket set Wera 05003647001 — 1/2" drive, imperial sockets and bits (assorted sizes)

Wera 05003647001 is a 38-piece Zyklop socket set with a 1/2" square drive designed for imperial (inch) fasteners. Supplied in a robust metal case, the set combines a ratchet with 72 fine-pitched teeth and a low 5° return angle, 18 imperial sockets in common inch sizes, extensions, a universal joint and a wobble extension, an adaptor with quick-release, a T-handle, and a selection of Torx bits (T20–T55). The Zyklop ratchet head pivots freely and can be locked in predefined positions for working in confined spaces, and the Kraftform handle is shaped for comfortable torque transfer and reduced hand fatigue.

Advantages

The Zyklop ratchet offers a low return angle and a 72-tooth mechanism for fine, precise operation in tight areas, while the pivoting and lockable head provides controlled access and safety during use. The set includes a range of imperial sockets and common Torx bits to cover many inch-based fastening tasks, and the quick-release adaptor and free-turning sleeve on extensions speed up socket changes and screwdriving. The metal case and colour-coded Tool Finder make storage and size recognition straightforward.

Suitable for

• Automotive repair tasks that require imperial socket sizes
• Mechanical maintenance and assembly with inch fasteners
• Work in confined or hard-to-reach spaces thanks to the pivoting, lockable ratchet head
• Fast screwdriving where Torx bits and rapid bit changes are needed

When it may not be suitable

This set contains imperial sockets and Torx bits; it is not intended for metric fasteners and will not replace a dedicated metric socket set when inch sizes are not used. Also, while comprehensive for inch applications, specialists requiring deep sockets, extremely long extensions, or a broader array of small hex/Phillips bits may need additional individual tools.

Key specifications

• Drive size: 1/2" square drive
• Number of pieces: 38-piece set
• Socket types included: 18 imperial (inch) Zyklop sockets covering a range of common sizes (including larger fractional inches up to 1-1/4")
• Bits included: Torx bits T20–T55 (selection of sizes)
• Ratchet: Zyklop ratchet with 72 fine-pitched teeth, approx. 5° return angle, pivoting head with lockable predefined positions
• Accessories: 2 extensions with free-turning sleeve, universal joint, wobble extension, adaptor with quick-release chuck, T-handle
• Handle design: Kraftform handle with rotation-symmetric core and anti-slip zones for torque transfer
• Case: Robust metal storage case with colour-coded Tool Finder for size identification

How to use

Select the appropriate imperial socket for the fastener and attach it to the 1/2" Zyklop ratchet or extension. Use the quick-release adaptor to secure sockets and bits, and operate the ratchet with short strokes enabled by the 72-tooth mechanism for work in confined spaces. For angled access, pivot the ratchet head and lock it in one of the predefined positions. The T-handle and extensions allow controlled torque application and reach, while the wobble extension and universal joint help access awkward angles.

What to consider before purchase

• Fastener system: set contains imperial (inch) sockets — ensure your fasteners are inch-sized
• Scope of sizes: check included socket sizes (up to approximately 1-1/4") against your needs
• Bit types: primarily Torx bits included — verify if additional bit types are required
• Storage and portability: set supplied in a metal case for workshop use rather than a compact pocket kit

Usage recommendations

Use the Zyklop ratchet for short, precise strokes in tight spaces and lock the head for safe, slip-free operation when working at set angles. Match sockets carefully to inch fasteners to avoid rounding, and use the quick-release adaptor for efficient socket changes during repetitive tasks.
