Cherry H781A-456 Compact Offset Pulling Head

The Cherry® brand H781A-456 is a new compact offset pulling head, replacing the popular H781-456 model. Its very compact size, light weight, improved strength and reliability, together with some unique new features, make it ideal for a diverse range of applications, including installing fasteners in restricted spaces. This pulling head will work directly with G746A, G747, G704B, G704B-40SH, G704B-SR, G800 and similar riveters. With appropriate adapters, other riveter models may be used.

Cherry TackMax - bringing applications together

The Cherry TackMax is a blind fastener designed to aid in assembly stack-up and automation. The fastener contains several anti-rotation features that aid in its removal without damaging the structure along, with a high-clamping force during installation to remove any remaining gap between layers. After installation, both ends of the fastener are designed with removal in mind, using built-in drill guides on both ends to reduce drill wobble. The fastener has also been optimized for automation by providing a high contrast red colored sleeve and tight tolerances on concentricity to the installation hole, allowing the head of the fastener to be a coordinate mark for vision systems.

The Cherry TackMax was designed around the Cherry One Tool concept. This means that existing single action installation tools from Cherry are capable of installing this fastener. No change in nose-piece is required for most tooling configurations. Consult the Cherry Product Expert for more information.
