· Product Overview

· Core Specifications

Material Performance

• 304 Stainless Steel
  • Tensile Strength: ≥515 MPa (rigid for high-load mounting and connection)
  • Corrosion Resistance: Passed 72-hour salt spray test (suitable for humid/industrial environments)
  • Food-Safe: Compliant with FDA 21 CFR 175.300 (ideal for food-processing equipment)
  • Hardness: 150–180 HV (balanced rigidity and ductility for repeated assembly)

Manufacturing Standards

• Certification: ISO 9001-Certified
• Key Processes: CNC Milling (oval base + mounting holes) → CNC Turning (cylindrical body) → Precision Tapping (internal threads) → Deburring → Surface Passivation → CMM Inspection
• Standard Parameters:
  • Oval Base Dimensions: 40×25mm (customizable 30×20mm to 60×35mm)
  • Cylindrical Body Diameter: 12–18mm (optimized for component fit)
  • Internal Thread: M8 (customizable to Metric/Imperial specs like M6/M10)
  • Mounting Hole Diameter: 4–6mm (compatible with M3/M4 fasteners)
  • Dimensional Tolerance: ±0.01mm (ensures precise alignment with mating components)
  • Surface Finish: Passivated polished (scratch-resistant, rust-proof, and smooth for low-wear operation)

· Application Scenarios

• Industrial Automation: Conveyor system component mounts, sensor installation bases, and robotic fixture connection points.
• Medical & Laboratory Equipment: Diagnostic instrument mounting studs, sample handling system supports, and surgical device fixture points.
• Food & Beverage Processing: Sanitary equipment mounting bases, packaging machine component studs, and brewing system connection points.
• Furniture & Hardware: Cabinet door hinge mounts, display fixture supports, and industrial shelf connection studs.
• DIY & Hobby Projects: RC vehicle chassis mounts, custom robotics fixture points, and workshop jig installation bases.

· Production Process Introduction

1. Raw Material Preparation: Cut certified 304 stainless steel round bars into blanks matching the stud’s overall dimensions.
2. CNC Milling: Use high-precision CNC mills to machine the oval mounting base and precision-drilled mounting holes in a single setup for maximum accuracy.
3. CNC Turning: Machine the cylindrical body to ensure concentricity with the base and thread alignment.
4. Precision Tapping: Create internal female threads with high accuracy to ensure secure mating with male fasteners.
5. Deburring & Finishing: Remove sharp edges from the base, body, and threads to prevent component wear and ensure safe handling.
6. Surface Passivation: Apply a chemical passivation treatment to enhance 304 stainless steel’s natural corrosion resistance.
7. Quality Inspection: Perform CMM dimensional scanning, thread fit testing, and load capacity validation to verify compliance with design specifications.

· Packaging and Shipping Methods

• Packaging:
  • Individual Pairs: Protected with anti-scratch foam padding, sealed in moisture-proof plastic bags, and labeled with thread specifications for traceability.
  • Bulk Orders: Packed in foam-lined partitioned boxes (prevents stud deformation, thread damage, and mixing of sizes).
• Shipping Options:
  • Express Delivery (DHL/FedEx): 3–5 business days for prototype or small-quantity orders.
  • Air Freight: 7–10 business days for medium-batch production runs.
  • Sea Freight: 20–25 business days for large-volume bulk orders.All shipments include full tracking and damage insurance.

· Frequently Asked Questions (FAQ)

• Lead Time: Standard lead time is 7–30 working days (includes CNC machining, passivation, and inspection); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—adjust base dimensions, body diameter, thread size/pitch, or switch to 316 stainless steel for extreme corrosion environments. Our engineering team validates designs for load capacity and component fit.
