Explore performance details, construction highlights, applications, and technical information in one clear overview.
The E12584 is a set of non-removable one-way screws intended for suitable industrial mechanical fastening applications. The M4 × 20 designation identifies the nominal screw size and length. The one-way configuration is designed to allow installation while making conventional removal more difficult. Ten pieces are supplied for multiple fastening points or replacement requirements. Application suitability should be verified before installation.
The screw features a one-way fastening arrangement intended to discourage routine removal. Its M4 × 20 specification provides a defined mechanical size for compatible mounting applications. The screws can be installed using an appropriate tool and suitable fastening method. Correct engagement with the mating component is important for secure assembly. The fastener should only be used where its specific fastening characteristics are appropriate.
The E12584 can help provide secure fastening in industrial equipment. Its one-way design can reduce the likelihood of casual or unauthorized removal. The ten-piece set provides multiple fastening components for an installation. The standardized M4 × 20 dimensions simplify selection for compatible mounting points. Mechanical performance depends on correct installation and the material of the mating assembly.
Select a compatible mounting hole and verify thread requirements before installation. Use the appropriate installation tool to avoid damaging the screw or mating component. Tighten according to the applicable mechanical requirements. It can be used in industrial equipment, machine assemblies and automation installations. Removal procedures should be considered before final installation.
