These rubber end stops are perfect for placing on the end of a linear rail to stop the carriage from running too far.

Use them in conjunction with the limit switches as a backup.

This metric fastener features a reduced head height of 1.5mm or less, allowing it to sit nearly flush against surfaces to prevent interference with moving parts in tight clearances. Its primary function is to secure mechanical components together without obstructing adjacent motion paths. It is designed for precise mechanical builds and structural assemblies with limited overhead space, such as securing brackets, plates, and V-slot wheels in 3D printers and CNC machines to avoid gantry or belt collisions. Additionally, it integrates into aluminium extrusion T-slot profiles and compact electronic devices to maintain space efficiency.

This post-insertion drop-in nut secures structural elements and auxiliary hardware anywhere along the channel of V-Slot or compatible aluminium extrusion profiles. It is placed directly into the open track at any assembly stage without requiring insertion from the rail ends, rotating to engage the underside of the channel when the mating screw is tightened. Typical applications include mounting brackets, sensors, and secondary plates to existing frames within 3D printers, CNC machines, and custom robotics structures. The nut locks into position and penetrates the anodised coating to establish a slip-resistant connection without requiring frame disassembly.
