Stainless steel 304 cross flat head slotted pins/pins (including circlip locating studs/cylinders) are a versatile fastener. The following is a summary of key customization requirements, clearly structured for easy reference.
I. Core Parameters
Stainless steel 304 or 316, material certification required.
Specifications and Tolerances
Diameter Range: M3, M4, M5, M6, M8, M10 (other sizes require mold making).
Length Range: Conventional 10-100mm (longer sizes require structural strength assessment).
Tolerances: Diameter ±0.02mm, Length ±0.1mm.
Head and Groove Type
Cross slot: Conforms to ISO 7045 standards, customizable to PHILLIPS or JIS specifications.
Flat head design: Head height recommended to be ≤1.5 times diameter, chamfer 0.2-0.5mm.
Circlip Groove and Locating Function
Groove width = circlip thickness + 0.1mm, groove depth 0.3-0.5mm.
Locking studs must be marked with thread length.
II. Surface Treatment Options
Process
Features
Applications
Natural Passivation: Basic rust-proof treatment
General industrial
Electrolytic Polishing: Mirror finish, good corrosion resistance
Food/Medical
Nickel Plating: Good wear resistance, poor conductivity
Electronic equipment
III. Customization Process
Requirement Confirmation
Submit drawings or samples.
Specify quantity: Wire EDM is recommended for small batches, and cold heading is used for large batches.
Proofing and Testing: Samples are produced within 3-5 working days, and a salt spray test report is provided.
Production Cycle: 10,000 pieces
Delivery Time: 7-10 days (including logistics).
IV. Quality Control
Testing Items: Hardness HRC 25-30, salt spray testing, and circlip fit slip force (special jig required).
Certification Support: RoHS/REACH (to be specified in advance).
5. Notes
Non-standard designs: Special-shaped grooves or double-start threads require additional mold fees.
Packaging: Default packaging is rust-proof, oiled, and bubble-bathed, vacuum-packed.
Through the above design, this fastener offers a balance of precision, strength, and adaptability, making it an ideal choice for mechanical transmission and structural connections.
