· Product Overview
These 304 stainless steel threaded standoffs (paired with matching hex nuts) are high-precision components engineered to space, align, and secure parts in assemblies—ideal for electronic, industrial, and precision equipment builds. Featuring a stepped cylindrical design, internal full-length threads, and a hex nut (for tool-free tightening), they combine corrosion-resistant 304 stainless steel construction with micron-level dimensional accuracy. The integrated nut ensures stable, adjustable fastening, making them a reliable solution for stacking PCBs, securing internal components, or reinforcing framework connections.
· Core Specifications
- Material: 304 Stainless SteelOffers excellent corrosion resistance (suitable for indoor/outdoor dry/mild-moisture environments), high tensile strength, and compatibility with standard assembly tools.
- Manufacturing Standard: ISO 9001-Certified Precision CNC Machining Process
- Key Processes: CNC turning (stepped outer profile + internal threads) → Precision thread tapping → Hex nut matching → Surface passivation (enhances rust protection).
- Key Parameters:
- Thread Specifications: Metric (M3–M6; customizable to UNC standards)
- Length Options: 10–50mm (standard: 20mm)
- Dimensional Tolerance: ±0.02mm (ensures alignment with mating components)
- Load Capacity: Up to 20kg per standoff
- Performance Rating: Torque resistance ≥15N·m (varies by thread size).
· Application Scenarios
These threaded standoffs are widely used in precision assembly:
- Electronic PCB Assembly: Stacking circuit boards, securing PCBs to chassis, or spacing internal modules in servers/communication devices.
- Industrial Automation: Reinforcing conveyor system components, mounting sensor brackets, or aligning robotic arm internal parts.
- Precision Instruments: Positioning delicate components in optical tools, lab testing equipment, or measurement devices.
- DIY & Prototyping: Building custom electronic enclosures, hobbyist robotics frames, or workshop jigs.
- Equipment Enclosures: Securing control panel modules or reinforcing internal framework in industrial cabinets.
· Production Process Introduction
- Raw Material Sourcing: Procure 304 stainless steel bars (metallurgically tested for thread integrity and mechanical strength).
- CNC Turning: Machine the stepped outer profile and drill/tap full-length internal threads to exact specifications.
- Nut Matching: Pair each standoff with a compatible hex nut (ensures tight, adjustable fastening).
- Surface Passivation: Apply a chemical treatment to boost the stainless steel’s natural corrosion resistance.
- Quality Inspection: Verify thread accuracy (via thread gauges), conduct CMM scans for dimensional tolerance, and test torque resistance.
- Sorting & Packaging Prep: Group standoffs by thread size/length for organized inventory.
· Packaging and Shipping Methods
- Packaging: Each standoff + nut set is sealed in anti-scratch, anti-static plastic bags; bulk orders are packed in foam-lined partitioned boxes (prevents thread damage and deformation).
- 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 sets per thread/size specification; small sample packs (20–50 sets) 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 standoff length, thread type (Metric/UNC), outer diameter, or material grade (e.g., 316 stainless steel) based on your technical drawings. Our CNC team will validate design feasibility for assembly compatibility.
