Situo Hardware specializes in custom 304 stainless steel hexagon socket shoulder screws, shoulder stop bolts, mold locating shoulder screws, and CNC non-standard shoulder positioning fasteners. We supply precision hardware for molds, tooling fixtures, testing jigs, automation modules, intelligent equipment, and mechanical positioning assembly.

This series of shoulder screws are integrally CNC machined from 304 stainless steel, featuring precision smooth shoulder sections and hexagon socket heads. Strict tolerances are controlled on shoulder diameter and length to achieve accurate positioning, limiting, and guiding functions. The threaded section provides clamping force, while 304 material delivers excellent rust and corrosion resistance.

• 304 Stainless Steel: Industrial grade material with uniform texture, free of pores and cracks. Excellent oxidation resistance, rust protection, and salt spray resistance.
• Integrated CNC Machining: One-piece turning processing with precision grinding on smooth shoulders. Tight tolerances ensure accurate positioning and maintain coaxiality.
• Hexagon Socket Head: Standard socket cap head distributes force evenly for high tightening torque and easy assembly/disassembly.
• Flexible Customization: Custom shoulder diameter, shoulder length, overall shank length, and thread size. Modified structures available with metric sizes as standard.
• Surface Treatment Options: Standard finishes include vibratory finishing and passivation. Polishing available for high-end precision instruments.
• Comprehensive Quality Control: Raw material inspection, dimension sampling, full inspection of shoulder diameter, thread testing, and burr removal.

• Positioning, guiding and limiting fasteners for plastic molds and stamping molds
• Stroke limit and positioning structure for tooling fixtures and testing jigs
• Guide & limit connectors for automation conveying modules and precision sliding tables
• Coaxial positioning assemblies for intelligent equipment and compact precision machinery
• Positioning fasteners requiring rust protection under humid working conditions
• Mechanical structures demanding precise clearance control and repeat positioning

Advanced equipment from Japan and Germany including CNC 5-axis and 6-axis machines. Maximum processing outer diameter: 60mm. Minimum control tolerance: 0.001mm.
