Situo Hardware is a professional OEM factory specializing in custom tool pins and fitting screw shafts, CNC machined precision tooling pin shaft mechanical hardware accessories. We focus on custom CNC machining tooling parts for industrial automation jigs, precision fixtures, mechanical molds, intelligent equipment and testing instruments.
All tool pins and screw shafts are integrally machined from solid industrial-grade stainless steel and carbon steel with pure CNC processing technology—no stamping, no die-casting and no welding splicing. The precision tool pins provide accurate positioning, guiding and limiting functions, while the matching screw shafts realize stable fastening and connection.
Our products effectively solve common defects of standard parts such as low precision, large assembly gap, positioning deviation and easy wear. They serve as core precision tooling accessories for mechanical and automation equipment assembly with full non-standard customization support.
- Pure CNC Machining for Higher Tooling Precision: All outer diameters, end faces, steps and thread structures are one-time CNC integrally cut, ensuring uniform size, excellent concentricity and strong interchangeability.
- High-Precision Tool Pin for Stable Positioning: Micron-level turning and grinding technology with key dimensional tolerances strictly controlled within ±0.005mm~±0.05mm for ultra-high repeated positioning accuracy.
- Solid Screw Shaft with Excellent Fastening Performance: Integrally cut from solid bar stock with full and neat thread teeth for tight occlusion and anti-slipping performance under high-load conditions.
- Multiple Industrial-Grade Material Options: 304/316 stainless steel for rust resistance; heat-treated high-strength carbon steel for heavy-load scenarios.
- Full Non-Standard Customization Service: Customize all kinds of non-standard tooling accessories including long/short tool locating pins, stepped pins, holed pins, and special-shaped pins.
- Strict Precision QC System: Full-dimensional inspection, coaxiality calibration, thread gauge testing, and simulated assembly testing with batch qualified rate over 99%.
- Precision positioning and limiting tool pins for automation jigs and fixtures
- Fastening and connecting screw shaft components for mechanical equipment assembly
- Anti-offset locating pin parts for precision molds and inspection tooling assembly
- Matching precision machined hardware accessories for intelligent equipment and instrument modules
- Durable tooling pins and screws for high-frequency disassembly, vibration and humid working environments
Situo Hardware has complete CNC machining capacity for custom tool pins and fitting screw shafts. Our workflow covers raw material selection, integrated CNC precision cutting, structural optimization, surface treatment and strict quality inspection.
