| Small Parts 142408RFA | 1/4″ | 1-1/2″ | 8-32 | Small Parts |
| Small Parts 141608RFA | 1/4″ | 1″ | 8-32 | Small Parts |
| Small Parts 140808RF303 | 1/4″ | 1/2″ | 8-32 | Small Parts |
| Small Parts 141206RFA | 1/4″ | 3/4″ | 6-32 | Small Parts |
| Small Parts 141606RFA | 1/4″ | 1″ | 6-32 | Small Parts |
For quick scanning, the table above highlights key specs. Each section below expands on a specific product, outlining dimensions, compatibility, and notable features. The selections aim to balance ease of use with durability, ensuring stable mounts and clean finishes in electronics assemblies.
Small Parts 142408RFA Aluminum Standoff
Material: Aluminum. OD is 1/4 inch with a length of 1-1/2 inches, and a female 8-32 thread profile. This model emphasizes lightweight strength and precise spacing for compact enclosures, panels, or PCB mounts. The generous length supports multiple mounting options while maintaining a slim profile.
Key considerations: good for laddered or stacked arrangements where extra length improves alignment; suitable for electronics racks, chassis, and instrument housings. The pack typically contains ten standoffs, offering economical bulk usage for projects with multiple mounting points.
Small Parts 141608RFA Aluminum Standoff
Dimensions: 1/4″ OD, 1″ length with 8-32 threads. The package typically includes a quantity suitable for mounting multiple components or interconnect boards within a compact frame. Aluminum construction provides a good balance of strength and lightness for small to medium electronics projects.
Notes: this variant is commonly used when a shorter mounting height is required, helping to reduce overall device depth while preserving rigid alignment across parts. It pairs well with standard panel hardware and mating fasteners.
Small Parts 140808RF303 Stainless Standoff
Material: 18-8 stainless steel with 1/4″ OD and 1/2″ length. This option uses stainless steel for corrosion resistance, making it suitable for environments with higher humidity or where long-term reliability is critical. Thread size remains 8-32, ensuring compatibility with standard fasteners.
Usage guidance: ideal for panels exposed to occasional moisture or outdoor-looking enclosures, but still intended for indoor electronics assemblies. Stainless construction can slightly increase weight, which is a consideration for ultra-light applications.
Small Parts 141206RFA Aluminum Round Standoff
Specifications: 1/4″ OD with 3/4″ length, 6-32 thread size. Aluminum construction provides reliable strength and easy machining compatibility for compact electronics assemblies. Length options like 3/4″ support mid-plane mounting while keeping overall device depth manageable.
Practical considerations: suitable for mounting boards or components that require a short, solid spacer between parts. Ensure thread engagement length is sufficient for the chosen screw or nut in your design budget.
Small Parts 141606RFA Aluminum Round Standoff
Dimensions: 1/4″ OD, 1″ length with 6-32 thread size. Like other aluminum variants, this standoff emphasizes light weight with solid load-bearing capacity. The longer length supports multi-layer mounting where board-to-board spacing is required without increasing the footprint excessively.
Considerations: appropriate for projects with stacked boards, chassis setups, or sensor arrays needing uniform spacing. Pair with compatible bolts or nuts to secure against vibration in dynamic environments.
Buying Guide
Choosing the right female threaded round standoff involves balancing dimensions, material, and thread compatibility. Here are key considerations to guide your decision:
- Thread compatibility: Ensure the thread size matches your fasteners (commonly 6-32 or 8-32 in these products). Mismatched threads can cause cross-threading and instability.
- Length vs. enclosure depth: Longer standoffs provide greater spacing but increase device depth. Measure your enclosure height and board thickness to pick an appropriate length.
- Material choice: Aluminum offers lightweight strength and good corrosion resistance; stainless steel provides enhanced corrosion resistance at the cost of weight. For sensitive electronics, aluminum is usually sufficient; for harsh environments, stainless may be preferable.
- Outer diameter: A 1/4″ OD is standard for compact electronics, but verify compatibility with mounting holes and standoff nuts in your chassis or panel.
- Finish and tolerances: Check for smooth threads and consistent diameters to ensure easy installation and repeatable performance, especially in dense assemblies.
- Bulk availability: Packs of 10–25 standoffs support larger builds and reduce per-unit cost, beneficial for multi-point mounting on projects like instrument panels or control racks.
- Durability under vibration: If the device experiences movement or vibration, consider locking fasteners or a slightly longer standoff to avoid loosening over time.
- Corrosion resistance: For humid or outdoor-rated enclosures, stainless variants offer longer life, while aluminum variants are typically sufficient in dry environments.
Overall, these options provide versatile solutions for mounting PCBs, panels, or components in compact electronics. When selecting, align thread size with your hardware, confirm the enclosure clearance, and verify that the length supports the intended gaps without compromising stability.
