Wera is a German company that produces sockets with a holding function. The holding function is designed to keep the socket and the fastener together during installation or removal, preventing the fastener from falling out of the socket.
The holding function is achieved through the use of a spring-loaded ball detent mechanism located inside the socket.

The ball detent engages with the fastener helping to retain it within the socket during positioning for insertion or extraction once undone. To release the fastener, the user simply pulls the socket off the head of the fastener or in the case of removed nuts, uses the Wera rubber nut extractor tool.
This holding function is particularly useful in situations where the fastener is difficult to access or if the user is working in an awkward position. It also helps to prevent damage to the fastener, as dropping it can cause dents, scratches, or other deformities that may compromise its performance.
Examples of applications where Wera sockets with a holding function would be useful include:
Automotive repair: These sockets are ideal for removing bolts or nuts from engines, transmissions, and other hard-to-reach areas.
Construction: When working on a construction site, it's important to ensure that all bolts and screws are securely fastened. Wera sockets with a holding function make it easier to do so, especially when working at heights or in tight spaces.
Machinery repair: When repairing machinery, it's often necessary to remove or replace fasteners in tight spaces. The holding function of Wera sockets makes it easier to do so without dropping the fastener or damaging the surrounding components.
Overall, the holding function of Wera sockets provides a reliable and efficient solution for working with fasteners, making it an indispensable tool for professionals and DIY enthusiasts alike.
