Spacer FAQs
What spacer types can you manufacture?
We manufacture all standard spacer types: round spacers (tube or disc with through-holes), square spacers (standoffs for PCB mounting), hex spacers, shoulder spacers (integral shoulders for precision location), stepped spacers (multiple diameters), threaded spacers (male or female threads), insulating spacers (plastic for electrical isolation), and custom profile spacers. Specify the profile and dimensional requirements on your drawing.
What materials are best for insulating spacers?
PEEK (polyetheretherketone) is the premium choice for high-temperature insulating spacers due to superior thermal and mechanical properties. Delrin (acetal copolymer) is cost-effective for general insulating applications. Nylon (polyamide) is the lowest-cost insulating option. PTFE (Teflon) is used for RF-shielding applications where electrical properties matter. Choose based on operating temperature, electrical requirements, and cost.
What tolerances can you hold on spacer lengths?
Standard CNC machining holds ±0.05mm on spacer length. For precision applications (stacked spacers or assemblies), we hold ±0.02mm. Cumulative stack tolerances are managed through careful sequential measurement. Specify your tolerance requirement and we will achieve it cost-effectively.
What is the typical lead time for custom spacers?
Lead time for custom spacers is 3–7 business days for small volumes. Simple spacers: 3–5 days. Complex profiles with threaded holes: 5–7 days. High-volume orders (100+) benefit from optimized tooling and faster turnarounds. Request a quote with your required delivery date.
Can you manufacture spacers with threaded holes?
Yes. Threaded holes are a standard feature. We machine tapped holes (metric or NPT), helicoil inserts (for soft materials), or threaded bosses. Specify thread size, pitch, and depth on your drawing. We offer M3–M12 standard sizes; custom threads are available.
Do you offer prototype spacer production?
Yes. Prototype spacers are manufactured to the same quality as production runs. Design review is included to optimize geometry for cost. We can modify designs, test materials, or recommend changes based on your application. Fast turnaround on prototypes: 3–5 days.
