High Precision Step Locating Pin Shaft
,Corrosion Resistant Shoulder Positioning Dowel Pin
,CNC Machined Locating Pin
Situo Hardware specializes in custom stainless steel step locating pin shafts and CNC machined shoulder positioning dowel pins. We supply non-standard precision pin components for industrial automation, tooling jigs, inspection fixtures, precision molds, and mechanical assembly.
Our stainless steel shoulder locating pins are integrally CNC machined from solid 304/316 stainless steel bar stock. The precision-machined shoulder step provides positive axial stop and consistent depth-limiting positioning. Additional features such as guide sections, threads, circlip grooves, and pin holes can be integrated in one piece.
- Corrosion-Resistant Materials: Dense 304 and 316 stainless steel bars free of pores and impurities
- One-Piece Step Shoulder Machining: Ensures high perpendicularity between step face and shaft axis
- CNC High-Precision Machining: Dimensional tolerances controlled within ±0.005mm to ±0.05mm
- Expandable Composite Structures: Integration of guide segments, circlip grooves, cross holes, and threads
- Comprehensive Customization: Custom step height, diameter, length, and composite structures
- Strict Quality Control: Batch qualified rate exceeds 99% with full inspection protocols
- Shoulder-step limit and axial-stop locating pins for automation jigs & fixtures
- Repeat-position shoulder stop dowel pins for inspection fixtures and precision molds
- Stainless steel step locating pins for intelligent modules and mechanical equipment assembly
- Precision assembly stations requiring controlled pressing-depth and anti-over-insertion protection
- Positioning assembly applications in humid and moisture-prone environments

It is a precision shoulder-type dowel pin with machined step face, mainly used for positioning and axial stop to control insertion depth and prevent over-insertion in jigs, fixtures, and mold assembly.
The integrated shoulder step provides physical axial stop, ensuring consistent assembly depth for every installation, which straight pins cannot achieve. This greatly improves repeat positioning accuracy of tooling systems.
Yes, we customize step height, diameter, total length, multi-stage shoulders, cross holes, threads, and grooves per drawings or sample parts.
