· Product Overview
These 304 stainless steel internal thread spacers are precision-engineered cylindrical components designed to create stable spacing between parts and provide reliable threaded connections in assemblies. Crafted from corrosion-resistant 304 stainless steel, they feature uniform internal threading (across the full length) and a smooth, passivated surface—delivering exceptional dimensional accuracy, long-term rust resistance, and consistent load-bearing performance. Ideal for both industrial and electronic applications, these spacers simplify component alignment while ensuring durable, secure connections.
· Core Specifications
- Material: 304 Stainless SteelOffers excellent corrosion resistance (suitable for indoor/outdoor dry/mild-moisture environments) and balanced tensile strength for thread integrity.
- Manufacturing Standard: ISO 9001-Certified Precision CNC Machining Process
- Key Processes: CNC turning (cylindrical outer profile) → Precision internal tapping (uniform full-length threads) → Surface passivation (enhances corrosion protection).
- Tolerances: Outer diameter ±0.02mm; thread pitch tolerance ±0.01mm (compatible with standard metric/UNC screws).
- Thread Options: Customizable to Metric (M3–M12) or UNC (#4–#10) specifications.
· Application Scenarios
These internal thread spacers are widely utilized in:
- Electronic PCB Assembly: Spacing circuit boards, connecting stacked components, or reinforcing PCB mounting points.
- Industrial Equipment: Joining metal parts in conveyor systems, securing sensor brackets, or aligning mechanical components.
- Precision Instruments: Positioning delicate parts in measurement tools, optical devices, or lab testing equipment.
- Furniture & Hardware: Creating stable threaded connections in custom shelving, cabinetry, or workshop jigs.
- DIY & Prototyping: Building custom mechanical projects, model frameworks, or small-scale device enclosures.
· Production Process Introduction
- Raw Material Sourcing: Procure 304 stainless steel bars with consistent metallurgical properties and dimensional uniformity.
- CNC Turning: Machine the cylindrical outer profile to exact diameter and length specifications.
- Internal Tapping: Use precision tapping tools to cut uniform full-length internal threads (ensures compatibility with standard screws).
- Surface Passivation: Apply a chemical treatment to enhance the stainless steel’s natural corrosion resistance.
- Quality Inspection: Verify thread integrity (via thread gauges), measure dimensional accuracy (CMM scans), and check surface finish.
- Sorting & Packaging Prep: Group spacers by thread size/length for organized inventory.
· Packaging and Shipping Methods
- Packaging: Individual spacers are sealed in anti-scratch plastic bags; bulk orders are packed in foam-lined partitioned boxes (prevents thread damage and deformation during transit).
- Shipping: Flexible logistics options:
- Express Delivery (DHL/FedEx/UPS: 3–5 business days)
- Air Freight (7–10 business days)
- Sea Freight (20–30 business days)All shipments include full tracking and damage insurance.
· Process
· Frequently Asked Questions (FAQ)
- MOQ (Minimum Order Quantity): 500 pieces per thread/size specification; small sample packs (20–50 pieces) are available for fit testing.
- Lead Time: Standard lead time is 7–10 working days after order confirmation; expedited production (5–7 working days) is available for urgent orders (additional fees apply).
- Customization Capability: Full customization is supported—we can adjust spacer length, outer diameter, thread type (Metric/UNC), or add chamfers (for easier screw insertion) based on your technical drawings. Our CNC team will validate design feasibility.
