Situo Hardware is a professional OEM factory specializing in custom stainless steel square non-standard parts and CNC machined special-shaped irregular mechanical hardware components. We provide one-stop custom precision machining for automation tooling, inspection jigs, intelligent equipment, medical devices, communication equipment and mold accessories.
All square and irregular shaped parts are integrally CNC milled from solid 304/316/316L stainless steel. We produce square blocks, rectangular bases, stepped square parts, slotted fittings, multi-hole mounting blocks and complex irregular structural components. Our products feature high flatness, accurate perpendicularity, tight tolerance and stable anti-rust performance, solving common defects of stamping parts such as low precision, deformation, burrs and poor assembly compatibility.
We select dense and pure industrial-grade stainless steel with uniform texture and stable mechanical properties. 304 stainless steel is widely used for general automation and tooling equipment with excellent rust resistance; 316/316L stainless steel provides superior acid, alkali and salt spray resistance for outdoor, medical, chemical and humid working environments.
All square and irregular components are one-piece CNC machined in a single clamping setup, eliminating secondary processing errors, tool marks and uneven surfaces. Strict flatness, parallelism and perpendicularity control ensures precise right angles and smooth burr-free surfaces. Key dimensional tolerances are controlled within ±0.005mm.
Free from standard part limitations, we customize all kinds of complex structures: solid square blocks, hollow square bases, stepped square parts, slotted components, multi-hole mounting blocks, eccentric irregular parts, polygon structures and arc composite shapes.
Multiple surface treatments are available, including wire drawing, mirror polishing, sandblasting, passivation and degaussing. Finished parts are smooth, scratch-free and burr-free with neat edges, meeting strict cleanliness standards for dust-free workshops and medical equipment.
One-piece solid cutting process without welding, splicing or bending stress effectively avoids deformation and rebound problems common in stamped or sheet metal parts. Low internal stress ensures stable structural accuracy under long-term vibration and temperature changes.
All finished stainless steel non-standard parts undergo full-dimensional inspection, flatness & verticality calibration, hole & slot position verification and simulated assembly testing before delivery, with a batch qualified rate over 99%.
They are precision custom mechanical components widely used for fixing, supporting, limiting and positioning in automation tooling, inspection equipment, intelligent modules and medical devices, especially for non-standard assembly positions where standard parts cannot fit.
One-piece CNC milling ensures high flatness, accurate verticality and zero deformation. Compared with stamping parts, they feature higher precision, better stability and smoother surface, suitable for high-precision repeated assembly scenarios.
Yes, we fully customize square, rectangular, stepped, slotted, porous, eccentric and arbitrary special-shaped structures according to customer drawings and samples.
We provide 304 stainless steel for general anti-rust needs and 316/316L stainless steel for enhanced salt spray, acid and alkali corrosion resistance for harsh environments.
We have introduced advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines). Our maximum processing outer diameter is 60mm, and the minimum control tolerance is 0.001mm.
