Socket Wera Zyklop 8784 A1 — 1/4" drive, imperial socket, 37 mm length

Wera Zyklop 8784 A1 is a 1/4" drive imperial socket with a 37 mm overall length, engineered for compact fastening and service tasks in confined spaces. The socket is designed to connect square drive tools to 1/4" hex bits and bit holders, complying with DIN ISO 1173-C 6.3 and E 6.3 interfaces as well as Wera connecting series 1 and 4. A quick-release chuck provides secure retention and simple bit changes, making the tool suitable for use with ratchets, adaptors and bit-holding extensions.

Advantages

The short 37 mm length offers improved access in tight assemblies while maintaining full engagement with fasteners. Compatibility with 1/4" hex bits and standardized interfaces ensures interchangeability with common hand tools and accessories. The built-in quick-release mechanism secures bits during operation and enables fast, reliable bit swaps without additional tools. The robust construction typical of Wera Zyklop sockets provides consistent torque transfer and resistance to wear under regular workshop use.

Suitable for

• Low-clearance fastening tasks in automotive and machinery maintenance
• Using ratchets or angle adaptors where imperial socket sizes are required
• Service work with bit holders, quick-change adaptors and portable tool kits
• DIY projects and technical repairs employing 1/4" hex bits

Key specifications

• Drive type: 1/4" square drive to 1/4" hex interface
• Length: 37 mm overall
• Socket type: imperial size (inch-based)
• Compatibility: DIN ISO 1173-C 6.3, DIN ISO 1173-E 6.3, Wera connecting series 1 and 4
• Retention: quick-release chuck for secure bit holding

How to use

Select the correct imperial socket size for the fastener and attach the socket to a compatible 1/4" drive ratchet, adaptor or bit holder. Insert a 1/4" hex bit into the socket until the quick-release mechanism engages. Operate the ratchet or drive tool with steady force appropriate for the fastener and application. To remove or change the bit, depress the quick-release collar and withdraw the bit, then insert the new bit until it locks.

Usage recommendations

Use the socket with tools and bits that match the specified 1/4" interfaces to avoid premature wear. Apply torque within the limits of your ratchet and fasteners, and keep the quick-release chuck clean of debris to maintain reliable bit retention. For repetitive or high-torque applications consider inspection for wear and replacement when signs of rounding or reduced retention appear.
