Hexalobular (6-lobe) cap screws, have a sixlobe recess and are driven using a 6-lobe wrench or insert bit, making them more efficient than slotted screws and hex drives screws. ZAGO’s machine screws are ready-to-use, as they do not require any preparation or clean-up. Our machine screws will continue to exceed your expectations for years on end, as they are reusable and vibration-resistant. In the case of extreme vibration, ZAGO offers self-locking strips, pellets and patches which absorb vibration and protect the integrity of the screw. Build your equipment with our screws, and enjoy superb machine performance for decades.
