The Wera Zyklop 35 Piece 8100 SB All-in Speed 38 Sq. Ratchet Socket Set is an impressively compact set of sockets and accessories that will cover a huge range of jobs. The 8100 SB All-in Zyklop Speed 38 ratchet set fulfils every mechanics and DIYer wish. Thanks to the Twist-to-unlock system, the ratchet can be easily removed. The ratchet head pivots freely and can be locked into any defined position by using the slide switch that is positioned on either side. It is even possible to work in very confined and difficult-to-access areas with enhanced hand clearance. The predefined locking at 0, 15 and 90, both to the right and left, ensure safe working without any slipping of the ratchet head. The Zyklop Speed ratchets are really fast movers. The gyrating mass design means that screwdriving is accelerated. The rotation-symmetric structure of the Kraftform handle and the freeturning sleeve reinforce this rapid twisting process, particularly when the ratchet does not engage due to too little resistance in the thread. The clamping of the screw is achieved by a twin spring loaded ball retention system. The tubing is effectively protected against mechanical wear and tear by a steel ring. The holding function is especially helpful in confined, hard-to-reach spaces, where there is no room for a second hand to secure the screw. The HF tools developed by Wera are ideal because they feature an optimised geometry of the original TORX profile. The wedging forces resulting from the surface pressure between the drive tip and the screw profile mean that TORX screws made according to Acument Intellectual Properties specifications are securely held on the tool The clamping of the screw is achieved by a flexible locking ball. The holding function is especially helpful in confined, hard-to-reach spaces, where there is no room for a second hand to secure the screw.
