FAQs: Fasteners for Automation Applications

Automation fasteners are precision-machined threaded components that join parts in robotic systems, conveyor assemblies, automated machinery, and industrial equipment. Types include socket head cap screws, button head screws, flat head screws, shoulder bolts for precise alignment, set screws with various drive types, threaded rods and studs, custom bolts with specialized heads or threads, and captive fasteners preventing loss during assembly.

Alloy steel provides maximum strength with tensile strength exceeding 1000 MPa after heat treatment, enabling high clamping loads in structural connections. Stainless steel offers corrosion resistance for washdown environments and cleanrooms while maintaining adequate strength. Aluminum delivers lightweight fasteners reducing overall assembly mass by 60 percent, ideal for moving parts in robotic systems. Brass provides non-magnetic and non-sparking properties for electronics assembly and sensitive equipment.

Swiss-type CNC turning produces complete fasteners from bar stock in single setups with high efficiency. Thread rolling cold-forms threads increasing strength by 30 percent over cut threads while creating smooth flanks. Precision turning machines critical dimensions including head geometry, shoulder diameters, and shank lengths. Drive recess machining creates hex sockets, TORX drives, or custom features. Heat treatment provides specified hardness and strength through quenching and tempering.

We provide tolerances of ±0.001 inches on body diameters, ±0.010 millimeters on thread pitch per ISO specifications, ±0.003 inches on head dimensions for proper tool engagement, and ±0.0005 inches on shoulders for applications requiring precise alignment and reliable clamping assembly integrity.

Yes, we provide rapid prototyping to verify fit and test assembly, with same-day CAD-to-part capability available for critical projects. For custom automation cells and research platforms, we perform low-volume production of 20 to 500 brackets. For standardized robot models, we perform high-volume production of thousands to tens of thousands of brackets annually, incorporating complete dimensional inspection, flatness verification, and material certifications.
