Stainless steel 304 cross flat head slotted pin is a multi-purpose fastener, usually used for mechanical positioning, axial fixation, or with a retaining ring to achieve anti-drop function. Stainless steel 304 cross flat head slotted pin is a precision mechanical connector. The following is the customizable range.
1. Material requirements
Material: Stainless steel 304 (ASTM A276/A479 standard), and material certification is required.
Corrosion resistance: Need to pass salt spray test, the common one is 48 48-hour neutral salt spray test, no red rust.
Hardness: HRB 70-90, can be adjusted according to the purpose, needs to be noted.
2. Dimensions and tolerances
Diameter: customized according to demand, tolerance ±0.01mm.
Length: Customization range 5mm~100mm, tolerance ±0.05mm.
Cross slot specifications: slot width 0.5mm~2mm, depth 0.3mm~1.5mm (drawing or standard number needs to be provided).
Flat head chamfer: The Default is 0.2mm×45°, which can also be adjusted according to the situation.
3. Process requirements
Surface treatment: The Default is bright polishing, optional sandblasting, or passivation treatment.
Notch processing: Laser cutting or precision milling to ensure no burrs and symmetry ≤0.02mm.
Heat treatment: Solution treatment or low temperature annealing is selected according to needs.
4. Performance verification
Torque test: Cross slots must withstand a tightening torque of ≥1.5N·m (adjustable according to size).
Straightness: ≤0.03mm/100mm.
5. Marking and packaging
Marking: Laser marking (the material, batch number, and position used must be negotiated).
Packaging: Anti-rust paper + foam box, 100~500 pieces per box (customizable quantity).
6. Additional services
Test report: Provide third-party size, material, and hardness test reports.
Samples: 3~5 samples will be provided after a 30% deposit is paid in advance, and mass production will be carried out after confirmation.
7. Notes: Detailed drawings or 3D models (STEP/IGS format) are required. If parameters are not specified, they will be implemented according to the general industry standards.
This type of pin achieves a balance between high-precision positioning, convenient maintenance, and environmental adaptability through the combination of structural design and material properties. It is an efficient solution for mechanical transmission and connection.
