This batch includes 50 M5, M6 and M8 Tslot bolts designed for standard aluminum extrusion profiles used with linear guide systems. The bolts fit profiles in 20, 30 and 40 series and are available in lengths of 20, 30 and 40 mm. An optional set of 50 M6 hex flange nuts (M6x20) can be added. Key benefits Versatile fastening for standard Tslot aluminum extrusion systems, enabling secure, modular mounting. Quick and straightforward installation and removal, supporting easy reconfiguration of assemblies. Sufficient quantity (50 pieces per batch) to support multiple projects or spare parts for ongoing work. Optional hex flange nuts provide convenient, flush mounting for M6 applications. Key attributes Functionality: M5, M6 and M8 Tslot bolts designed to slide into Tslots and accept corresponding nuts for clamping. Compatibility: Suitable for standard aluminum extrusion profiles in 20, 30 and 40 series used with linear guide components. Size options: M5, M6, and M8 thread sizes. Length options: 20 mm, 30 mm, and 40 mm. Material: Not specified in the listing. Packaging: 50 pieces per batch. Optional accessory: 50 pieces M6 hex flange nuts (M6x20) available as an addon. Use cases CNC machine or 3D printer frame construction: use M5/M6/M8 Tslot bolts to attach brackets, plates, or mounting blocks to the extrusion profiles, with fast and repeatable assembly. Mounting a linear guide rail to an aluminum profile: secure the rail with appropriate Tslot bolts and nuts, enabling precise alignment and easy adjustments. Adjustable fixtures and workholding: create modular fixtures on a workbench or jig station by connecting components at multiple points along the profile for flexible positioning. Notes Ensure you select the correct length (20, 30, or 40 mm) to suit the profile depth and mounting requirements. If adding the optional M6 hex flange nuts, consider the M6x20 specification for proper compatibility with the bolts.
