    CM-30M

    The SEALS CM-30M Magnetic-Type Automatic Screw Feeder is designed to provide high efficiency and precision in handheld screw fastening applications. Utilizing a push-pull jaw mechanism and a magnetically driven bit, the screw is instantly ejected and securely held at the tip, fully exposed for quick and accurate alignment with the screw hole. This design is especially ideal for challenging environments where traditional jaws cannot reach—such as deep holes, wiring areas, curved surfaces, or tight spaces near walls—enabling precise fastening even under constrained conditions. The electric screwdriver set features a lever-activated, brushless torque control design, offering high precision, easy torque adjustment, and long-term durability. Without carbon brushes, the driver remains cool during extended use and provides a more comfortable experience for the operator. The screw feeding unit is built to be rugged and durable, with a simple and compact structure that allows for quick installation and easy adjustment. Most importantly, setup can be completed by a single operator with minimal effort.

    CM-20M

    The CM-20M is a handheld automatic screw fastening solution that integrates vibratory screw alignment, air-blow screw feeding, and trigger-activated fastening operation. This configuration allows operators to maintain a stable cycle time even when working at mobile stations or in multi-angle fastening applications. After alignment, screws are delivered to the fastening point via air-blow feeding and positioned by a magnetic driver bit, ensuring stable alignment and improved positioning accuracy during the initial fastening stage. During operation, the operator simply pulls the trigger, causing the driver bit to advance the screw and complete the fastening process. Since this fastening method does not require the front sleeve or fixture to press against the workpiece surface, it effectively reduces the risk of scratches or surface marks. This makes the CM-20M especially suitable for cosmetic parts, painted components, anodized surfaces, or products with surface protection requirements. It should be noted that the positioning mechanism of the CM-20M relies on the driver bit’s ability to hold the screw magnetically. Therefore, only screws with magnetic properties are applicable. For non-magnetic screw materials—such as most stainless-steel screws—a push-down type fastening model without magnetic dependency is recommended to ensure stable feeding and fastening performance.
